Trailer Rings, Turntables, Slewing Rings & Slewing Drives



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.

Trailer rings or turntables offer a cheap rotation solution used in the right conditions.


Slewing Drives combine a slew ring and worm shaft to offer a compact and all-in-one solution to many rotation problems



QCB offers one of the widest product ranges around!

With a huge database of drawings and interchange information, coupled with our design and selection service, it's little wonder that we are the first call for many clients - either in the UK or further afield. 

NBC Group manufactures slewing rings and slew drives under the brandname of QCB® and offer equivalents to other brands such as Torriani Gianni, La Leonessa, BRB Technologies, INA-FAG (now the Schaeffler Group), RoballoRoth Erde, Rollix Defontaine, Avon, Taperex, Kaydon, Rossi, RKS, SKF, RIMA, IMO, Titanus, PSL, Drecon, Jost, and BPW 

A wide range of stock sizes (up to 2 000mm diameter) is available; any other designs in ball, x-roller, angular contact, double row, triple row or even wire race bearings can be considered up to 15 000mm outside diameter.

Our Product Specialist has some 30 years experience of the product, and we believe this sets us apart from many "number traders" in this market. Over the years we have supplied bearings for aerospace and military applications, high radiation area nuclear handling equipment, large diameter offshore applications (with full DNV Certification) and many other "specials" including split slewing rings - with worldwide delivery direct from the factory if need be.

NBC is big enough to hold stock for OEM customers, yet small enough to care about single unit demands.

We make no claim to be agents of these companies - but we are able to discuss their products and our equivalents with you as we have extensive experience, as well as catalogue and drawing file information on file.
