Turntable bearings (sometimes referred to as slewing ring bearings) are 4 point contact thin section type ball bearings that have holes in both the inner and outer rings for easy mounting. Crossed-roller bearings are bearings for high-precision applications whose dimensions conform to ISO dimension series 18 as per DIN 616. They comprise outer rings, inner rings, rolling elements and plastic spacers. The outer ring is split and is held together by three retaining rings.

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.
Single-row ball slewing bearings with flange are often referred to as the “light series”.
Single-row ball slewing bearings are the most commonly used slewing bearings.
DV-B double-row ball slewing bearings are usually manufactured as eight-point contact bearings with two symmetrical ball raceways.
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).
All slewing bearings in the X1 series are crossed-roller bearings.
|Type||Cross Roller Bearing|
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.

QCB is known for innovative design, high quality and customer service. QCB supplies to OEM manufacturers internationally, as well as bearing traders and end users. QCB offers one of the widest ranges of slewing rings and slewing drives available from a single supplier, and has become a trusted name in slewing ring bearings with a satisfied and international customer base in industries as diverse as mining machinery, materials handling, military, nuclear, offshore oil and gas, access platforms, process treatment plants, wind power, special effects and art installations.
Slewing rings carry large axial, radial and moment loads within a compact dimension envelope and are used in a wide range of industrial machines. Their use offers an elegant solution to the problem of load carrying, stability and power transmission.
Design, Installation & Maintenance
A series of metric and imperial sized light duty slewing rings for a wide variety of industrial applications
A series of solid section slewing rings, with either a ball, or crossed roller construction. This series of rings can again be used in a variety of wide ranging applications.
A series of 90mm tall flanged slewing rings, for more heavy duty applications where loads are predominantly concentric.
A series of solid section slewing rings designed to support heavier loads in more demanding applications.
NBC Group boasts an ever growing list of slewing rings available from stock.
Double row ball slew rings are ideal in applications where a high moment load is to be supported, a degree of rigidity is required in the bearing system, or there are high radial loads.
Used for very heavy loads and available in either geared or ungeared forms from 634mm to over 12 000mm diameter (possibly segmented)
High precision rotary turntables
QCB Thermoplastic Housings are manufactured in a high-grade PBT glass-filled thermoplastic polyester and are dimensionally interchangeable with conventional cast-iron housings, resulting in a maintenance free housing with excellent mechanical strength, stiffness and dimensional stability that will never rust or corrode.

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.
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.
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 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.
