- 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
- 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
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.
- Flanged Heavy Series
A series of 90mm tall flanged slewing rings, for more heavy duty applications where loads are predominantly concentric.
- Solid Section Medium Series
A series of solid section slewing rings designed to support heavier loads in more demanding applications.
- 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)
- Precision Rotary Turntable Bearings
High precision rotary turntables
- Thermoplastic Housings
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.
