Linear motion parts are parts for a linear motion mechanism. Linear motion parts are widely used in various industries such as machine tools, semiconductor manufacturing equipment, etc. The linear bushing is a linear motion mechanism that uses a cylindrical shaft, and the steel balls of the cage roll while making point contact with the shaft, enabling highly accurate linear motion with minimal frictional resistance. Ball screws are devices that convert the rotation of a screw shaft into linear motion. Using a motor, etc., it is also possible to change rotary motion into linear motion and linear motion into rotary motion. Linear guides are bearings that provide smooth movement in the direction of rails, and feature low friction due to the rolling motion of steel balls. The linear guide has no propulsion, so it is used in combination with a cylinder or motor, ball screw, etc. There are also single-axis actuators and single-axis robots that integrate a ball screw, a linear guide, and a motor to reduce the number of assembly steps.

Linear guides
Linear guides provide a precise guiding function for positioning loads in combination with linear motion driving elements, such as actuators or ball screws. Our linear range includes precision rail guides, various profile rail guides and linear ball bearings, as well as units with precision shafts. From a few microns of stroke up to several meters of movement, almost any precise motion application in industrial or office environments is possible. The high product standardisation provides high-quality components even for applications with the lowest friction or noise emission request.
Linear bearings, units and shafts
Features:
· Wide range of bearings sizes from 3 to 80 mm
· Optional in stainless steel design
· Linear ball bearings (also called ball bushings or shaft guides) are cost-effective and widely used linear guide systems used in a variety of applications. The guiding principle consists of three elements: linear ball bearings, bearing housings and precision shafts. The wide range of diameters combined with the different types of bearings, housings and shafts make it easy to use and flexible to design in. Shaft guides provide low-friction guidance at unlimited travels and high tolerance to misalignments.
Miniature profile rail guides
Miniature profile rail guides are made for applications requiring compact, high running accuracy, long service life and low noise. Ewellix LLS systems offer extremely smooth running behaviour. The robust ball retention system avoids surprises during mounting.The products are ready to install while pre-lubricated with a lubrication reservoir for long service life. Rails and carriages (blocks) both have two reference sides for easy mounting.
Ball profile rail guides
The ball profiled rail guides are widely spread in many industries and are nearly used for any linear guide application. They are equipped with 4 rows of ball-bearings at right angles. Thanks to the X arrangement with rails and carriages (block), larger differences in height can also be made up. This superior design ensures reliable and friction-free operation of a linear motion system. The carriages can be replaced with the same rail size, simplifying maintenance and installation.
Precision rail guides
Ewellix precision rail guides provide the highest precision in motion and are used in high end industrial, medical and electronic applications. They are available in a wide range of sizes and rolling element options. The non-circulating rolling elements provide outstanding smoothness in motion. Ewellix Anti-Creeping-System (ACS) ensure position accuracy as it avoids cage creeping.
Roller profile rail guides
Roller profile rail guides are the high-end guide solutions for applications like machine tools, automation industry or plastic injection moulding machines. Ewellix LLU guide systems offer high precision and rigidity at the highest load ratings with the most compact design. The LLU carriages (blocks) are interchangeable within the standard precision classes for standard rails.

Egis Precision Flat Cage Guidance Systems, a medium-sized Swiss company, has specialized in making precision linear guidance systems for 50 years. Egis systems are essential in fields such as machine tool construction, printing machines, measurement technology, automation, robotics, optics, productronics, and medical technology.
In addition to standard high-precision guideways, EGIS also produces them in made-to-measure lengths, the associated flat and angled flat cage assemblies, and offers manufacturing possibilities for special parts to suit customer requirements.
Egis M and V Guideways with Needle or Cylindrical Roller Flat Cage AssemblyM and V guideways are combined with angled flat cage assemblies and are particularly suitable for high load carrying capacities, rigidity, minimal friction and a high level of accuracy. They are used as linear locating bearings. They are manufactured in standard lengths up to a maximum of 1,000 mm which allows for rapid delivery.
In order to respond to specific customer requirements, the guideways in this range can also be supplied in made-to-measure lengths, i.e. in any required length up to the maximum length specified in the dimension table.
The guidance systems can be set to be free of clearance or can be preloaded to enhance rigidity using pressure screws.
Egis ML Guideways with Adjusting GIB for Needle Roller Flat Cage Assemblies
This series combines an M guideway with an adjusting gib which distributes the preload equally over the entire length of the guidance system.
The pitch of the gib surface is 1.5%. ML guideways fulfill optimum requirements in terms of rigidity and precision.
Egis MVZ (M/V/ML) Guideways with Integrated Toothed Rack for Positive Control of the Needle Roller Flat Cage Assembly
In this series, the angled flat cage assembly is subjected to positive control by an integrated toothed wheel/toothed rack unit. This guarantees perfect movement for the flat cage assembly even under difficult operating conditions.
The guideways in this series consist of an unhardened guideway with a layer fixed by adhesive. They are combined with V guideways and possess the same mounting dimensions as the M/ML and V guideways with flat cage assemblies. They are used in particular when an increased level of friction is required to provide damping or when static or pulsating loads are involved.
These guideways are used in combination with needle roller flat cage assemblies as linear non-locating bearings. They are supplied in two versions, one of which possesses a flat structure and is therefore space-saving whilst the other has the same dimensions as the corresponding M and V guideways.
Egis LUE Counterstay Systems with Needle Roller and Cylindrical Roller Flat Cage AssembliesThese units consist of a locating guidance system, a non-locating guidance system and an L counterstay which preloads the two guidance systems. This arrangement prevents the system from becoming distorted by thermal expansion.
Egis Flat Cage AssembliesFlat cage assemblies consist of a basic cage made from plastic or metal and a large number of precisely guided rolling elements. Needle rollers provide a minimal construction height and optimum load carrying capacity and rigidity whilst cylindrical rollers are less demanding with regard to the connecting structure and have a slightly less rigidity. Balls create the lowest level of friction of all rolling bearings.
Flat cage assemblies are designed for use with precision guideways but can also be used directly with customer-specific elements with appropriate raceways.

Mar Motion bearings have even been used on the Hubble telescope.
Originally developed by Mahr in order to increase the measuring accuracy and certainty of its dimensional metrology products, Mar Motion high-precision rotary stroke bearings are used in measurement transducers, positioning units, centering and tilting tables, and in other modules that have an influence on the measuring result. Mar Motion high-precision rotary stroke bearings exhibit virtually no backlash, stick slip or wear, and their motion is exceptionally smooth and reproducible.
Other popular applications for Mar Motion Rotary Stroke Bearings include uses such as components in packaging machines in a wide range of industries, in automatic assembly units, textile machines, and high-quality special-purpose machines.
Mar Motion bearings are used in optical engineering to enable stick-slip-free movement of lenses, mirrors and diaphragms, and are suited for both large and heavy optical elements as well as for miniature design in small objectives.
In precision engineering applications where miniaturization requires compact instruments, Mar Motion MINI series rotary stroke bearings provide stick-slip freedom, easy movement and maintenance-free operation. Small ball diameters reduce installation space, and ‘Minis’ come paired without play for components including small control elements for placer heads and laser welding technology, as well as blade holders, jigs or fixtures.
Mar Motion high-precision rotary stroke bearings assure high guiding accuracy for both linear and rotary movements. The size and form accuracy (roundness and cylindricity) of the micro-finished running faces of shafts and bushings is less than 1/3 ISO standards; and only grade 5, sorting class P0 steel balls (DIN 5401 or ISO 3290) are used. Factory– preloaded balls and a low coefficient of friction virtually eliminate backlash and ensure smooth operation.
The extensive range of Mar Motion high-precision rotary stroke bearings offers appropriate solutions for many different applications. Options include various thread combinations of guide shafts; closed or open guide bushes with or without stop rings; sealing rings or wipers; and plastic or brass ball cages with ceramic or stainless steel balls. Mahr can also manufacture special designs for particular applications and requirements, or use alternative materials.
Mar Motion high precision Rotary Stroke Bearings are the bearings of choice for backlash-free linear, rotary or combined movements where precision is essential, like:

Principles of operation
Linear guides – the key part of precision instruments – are used in conjunction with compact ball screws which are locked onto a platform and linked to a servo motor, to produce linear motion. The main function of the guide is to allow the platform to maintain high precision, high rigidity and high load motion.
STAF linear guides have a common rail, interchangeable alloy steel slide, designed for reliability and flexibility. The dust sealing twin lip structure ensures effective sealing and the large internal lubricant storage facility reduces maintenance requirements and extends the service life of the system.
Cage and non-cage types, which are fitted on the same profile rail, have new patented features which include a ball re-circulation design, with no gap, for smooth running. The newly designed chain lubrication system reduces friction during operation and extends service life of the system.
The BGC cage-type linear guides, which are suitable for high-speed applications, contain lubricant between the steel balls. The friction produced during operation is reduced by the oil film. Advantages over conventional systems include reduced contact pressure, lower noise levels, less vibration and lower heat generation.
In traditional guides, the steel balls collide, producing a sharp, screeching noise and are easily worn out. BGC linear guide cages are manufactured from macro-molecule polymer, with lubricant space designed within the chain belt. With the flexibility of the chain belt and the cushioning effect of the lubricating oil, most of the noise produced from the chasing effect of the steel balls is eliminated.
The BGC steel ball retainer has a fixed distance retaining function so that each steel ball receives a balanced force for stable operation and extended service life. The issue of irregular gaps is far smaller than with traditional linear guides.
The BGX non-cage series, with a four-groove design, ensures even load capacity in all directions, irrespective of how the rails are mounted. An auto adjust capability prevents assembly errors and allows quick, accurate linear motion by eliminating the deviation of the mounting planes. Advantages of this four-groove series over the conventional two-groove design, include quick, light movements, reduced friction, high load ratings and improved stability.

The accuracy of linear guides depends on the efficiency of circulation of steel balls between the slide and the rail. The incursion of the smallest objects can cause skipping and bumping of the slide and lead to permanent damage.
The advanced seal design of the BGX series is divided into top and bottom seals systems to prevent the incursion of foreign objects. The top seal system prevents particles caught at the rail holes from entering the circulation groove and the bottom seal system prevents objects from entering through the gap in between the slide and rail.
STAF has also developed micro linear guides – the MBX and MBC series, with an integrated dust-proof design and an efficient lubrication system. These miniaturised cage and non-cage types, have application advantages that include high precision, low noise levels and extended service life.
