Turntable & Crossed Roller Bearings

Product Details:

Cross roller bearings between wheel and ocean shipping, interval cross each other to the square arrangement way they can also inherit from each direction load (such as axial thrust or momentum load, etc.) for roller and track surface into linear contact, robot special cross roller bearing.

Cross roller bearing characteristics of use:

• Have excellent rotation accuracy
• Operation installation simplified
• Bear the larger axial and radial load
• Greatly save installation space
• Speed ability high
• Reduce the axial length and processing cost, thermal expansion leads to the change of geometry size limited
• Using nylon dividers, moment of inertia is low, starting torque low, easy to control the Angle index
• Optimization of prestressing force, stiffness, guide roller running high precision
• Carburizing steel provides excellent resistance to impact and surface anti-wear ability
• Simple but lubrication fully

IKO CRBF Crossed Roller Bearing

Thin-section crossed roller bearing of series CRBF (inner ring division) .The inner ring of bearings are designed for two parts, but their outer ring as a whole .This kind of design is most suitable to apply in the highest rotating precision of outer ring.

Both the inner ring and the outer ring have integrated structure (Inseparable), and attachment holes are made to the inner ring and outer ring so attachment can be made easily. Furthermore, it is not easily affected by surrounding structures such as housing and presser plate, therefore, a high rigidity and high accuracy rotation are realized.

DV-B Drehverbindungen Bautzen GmbH designs and produces slewing bearings and gear rims that are used in many different and distinct sectors of industry.  DV-B Drehverbindungen Bautzen GmbH  Started in 2007  & extensive expertise and competence in the bearings industry due in large part to there sister company MBT Maschinenbauteile Scholze, which was founded in 1992.

Products:

• L1 series (Single-row ball slewing bearings with flange)

Single-row ball slewing bearings with flange are often referred to as the “light series”.

• K1 series (Single-row ball slewing bearings)

Single-row ball slewing bearings are the most commonly used slewing bearings.

• K2 series (Double-row ball slewing bearings)

DV-B double-row ball slewing bearings are usually manufactured as eight-point contact bearings with two symmetrical ball raceways.

• R3 series – Triple-row roller slewing bearings

Slewing bearings in our R3 series have the highest static and dynamic load capacity thanks to their three roller raceways (one supporting, one retaining and one radial raceway).

• X1 series (Crossed-roller slewing bearings)

All slewing bearings in the X1 series are crossed-roller bearings.

1. Gear rims- Gear rims are toothed rings, which, in contrast to gear wheels, do not sit directly on an axle, but are usually screwed to a component with the help of fastening bores.
2. Pinions- In addition to gear rims and geared slewing bearings, we can design and supply the matching pinions following the load capacity calculation.

 

Product Details:

RE Crossed roller bearings are lightweight, compact bearings with thinnest possible inner and outer rings with high rigidity, because of its vertical arrangement of cylindrical rollers with a 90°V groove through the separate spacers in the deep groove rolling surface. This special design allows just one bearing to carry loads in all directions including radial, axial and moment loads.

With over 25 years of experience, TGB Group is a leading company in transmission and motion solutions for the industrial and solar markets. TGB develop and manufacture technological products that are distributed worldwide with the highest quality standards.

 TGB Group Technologies is a world leader as a manufacturer and distributor of slewing rings, slewing drives, linear guides and actuators.

Products:

• Slewing Drives

The rotating modules are compact rotational units integrated in a cast iron housing that contains a turning ring with a gear. The gear rotates the turning ring with great precision and allows for smooth rotation and maximum effort.
The rotation modules can support axial, radial and inclined loads and are completely sealed.

• Slewing Rings

TGB have variety of single and double row roller bearing products designed to absorb axial and radial forces such as tilting forces. The slewing rings are sealed on both sides to protect the rolling elements from dust, foreign materials and to prevent grease leakage.  

TGB Group Technologies manufactures motion solutions that are used under the toughest conditions:  available  special anti-corrosion treatment, special surface coatings for heavy industry (off-shore), hardening purposes and measures on the raceways and internal gears, etc.

Slewing rings are used in applications such as construction equipment, platforms, cranes, accessories, demolition equipment, packaging equipment, food processing equipment, turntables, satellite antennas, trailers, etc.

• Linear Actuators

Linear actuators are devices that are responsible for transforming a rotary movement provided by a motor in linear motion thanks to the combination of a steel auger and a bronze toothed ring; These devices are prepared to work under difficult conditions or environments where the working temperature range is between -10ºC and 60ºC.

TGB Group Technologies manufactures two main types of linear actuators: screwdriver or telescopic. The main difference between the two is that in the first type, the spindle has a metal cover on the back and a rubber cover on the front, while the telescopic only protrudes the spindle on one side and is covered with a tube chrome plated.
