Feature
These 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. bearing tapered, tapered bearing 
Single-row bearings can carry radial load and axial load in one direction.
Double-row and four-row taper roller bearings can bear the radial load and axial load in double directions.
Cages
Normally there taper roller bearings use pressed basket-shaped cages of steel sheet. But for cages with greater machined dimension, cages are also used.

GWG Bearings manufactures both metric and inch-sized single row, double-row and four-row taper roller bearings. bearing tapered, tapered bearing, taper bearing, tapered roller bearing, taper roller bearing, single row tapered bearing, double row tapered bearing, four row tapered bearing, bearing china tapered
