Backing Bearings
LYNBC backing bearings based on cylindrical roller bearings have two or three rows of rollers and are available as full complement bearings (without cage) or as caged bearings, with or without integral flanges or flange rings. The advantage of the bearings without flanges lies in their particularly simple geometrical form and their very high radial load carrying capacity.
1. Cylindrical roller backing bearings
2. Needle roller backing bearings
3. Tapered roller backing bearings
▲ The design’s of all these backing bearings are based on standard structures; LYNBC can design and manufacture many other similar structures in accordance to the special and particular requirements of their customers’. If our customer’s have specific requests then the customer should identify the structure, and mounting dimensions that are required. Please contact the LYNBC Technical Center if you need any assistance in this area.
