The bearings have tapered rollers which are guided by the thicker side of the cup. The design of the sliding surfaces of the cup and inner ring and the rolling elements when extended converge towards the same single point on the bearing axle.
Single-row tapered roller bearings can carry radial load and axial load in one direction.
Double-row and four-row tapered roller bearings can bear the radial load and axial load in double directions.
Cages
Normally the tapered roller bearings use pressed basket-shaped cages of steel sheet. But for cages with greater machined dimension, machined cage is also used.
TIK manufactures both metric and inch-sized single row, double-row and four-row tapered roller bearings.
