Specification:
Tapered roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged. The rollers are guided by the flange of the inner ring.
The projection lines of all the tapered surfaces meet at a common point on the bearing axis.Single row taper roller bearing can bear radial load and one way axial load; Double row taper roller bearing can bear radial and double way axial load, also with capacity of bearing heavy load and impact.
