Tapered roller bearings mainly burden the joint load from radial and shaft side. This kind of bearings has strong load capability. It belongs to separated bearing; its inner components and outer components can be equipped individually.On small and medium sized dimensions, our tapered roller bearings use P5 or equivalent techniques; and adopt entire convexity design.

Cone (inner ring assembly) and cup (outer ring) combine to form a complete single tapered roller bearing
Supports high radial loads and axial loads in one direction between a rotating and non-rotating member
Operating temperatures range from -30 to 120 degrees C (-22 to 250 degrees F)
Sheet steel cage evenly spaces rollers for reduced friction, vibration, and noise
Open configuration for lubrication applied in place
Mainly used in motorcycle rear axle wheel hub, heavy machine tools' main shafts, big power reduction gears, axletree axle boxes, roller wheels of transportation devices, and the supporting rollers and working rollers of the rolling mills.
