Inch Tapered Roller Bearings

Inch Tapered Roller Bearings

FRB BEARINGS  Produce Inch Tapered Roller Bearings
have tapered inner and outer ring raceways between which tapered rollers are arranged.The projection lines of all the tapered surfaces meet at common point on the bearing axis.Their design makes taper roller bearings particularly sutiable for the accommodation of combined (radial and axial) loads.

FRB BEARINGS Tapered roller bearings are a unique subset of axial roller bearingsin which the rollers are tapered rather than straight right cylindrical. The roller shape allows thrust loads to be withstood in addition to the radial loads.

Applications:
Roll-neck applications in rolling mills, transmissions gear reducers, geared shafting, steering mechanisms, and machine-tool spindles.Where speeds are low, grease lubrication suffices, but high speeds demand oil lubrication - and very high speeds demand special lubricating arrangements.
