Slewing Rings

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

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.

Flanged Light Series

A series of metric and imperial sized light duty slewing rings for a wide variety of industrial applications

Solid Section Light Series

Other Stock Slewing Rings

NBC Group boasts an ever growing list of slewing rings available from stock.

Double Row Ball Slew Rings

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.

Triple row slewing rings

Used for very heavy loads and available in either geared or ungeared forms from 634mm to over 12 000mm diameter (possibly segmented)


Standard and special design pinions

Ring Gears

An offshoot of our usual slewing ring sales, internal or external ring gears with matching pinions are imported to special order. Up to 16 000mm gears (segmented for shipping) with 1000mm gear face width can be considered. matching pinions or pinion…
