Single-row Tapered Roller Bearings

Single-row Tapered Roller Bearings

FRB BEARINGS Produce Single-row
Tapered Roller Bearings are the most widely used tapered roller bearings. They have a high radial capacity and a thrust capacity about 60% of radial capacity. The exact percentage depends on the size of the tapered roller bearing. Variations within the type include tapered bores for frequent removal, pin cages and hollow rollers for higher capacity, and steep roller angles for higher thrust capacity.

FRB BEARINGS Tapered roller bearings are widely used in roll-neck applications in rolling mills, transmissionsgear 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.
