Four-row Tapered Roller Bearings

Four-row Tapered Roller Bearings

FRB BEARINGS Produce Four-row Tapered Roller Bearings
have characteristics similar to two 2-row tapered roller bearings mounted side-by-side. These tapered roller bearings are used to provide high capacity or to accommodate special mounting problems.

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.

The parameters as follows:
