We are a factory specializing in manufacturing and exporting bearings. We could also manufacture products according to your special requirements, we will provide a more favorable price. Taper roller bearingare generally used to support combined load mainly consisting of radial load. Their cups are separable for easy assembling. During mounting and using, radial clearance and axial clearance can be adjusted and preloaded mounting can be made.
Taper roller bearingare uniquely designed to manage both thrust and radial loads on rotating shafts and in housings.
Taper roller bearingare designed to carry both thrust and radial loads and consist of four components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer. Tapere roller bearingmainly carry radial, axial combined load with radial load in the main. The capacity of axial load carrying depends on the contact angle of outer ring's raceway. The bigger the contact angle is, the greater the capacity will be.
Taper roller bearingthe angle between the outer raceway generatrix and line, the bearing can bearing heavy load and other Tapered Roller Bearings, it mainly bears joint load based on one way axial load,but not only radial load.
Series models sp
tapered roller bearings
Single row tapered roller bearingsare separable radial bearings:
Suitable for high radial loads and thrust loads (in one direction)
Take up tilting moments
When paired, can take up thrust loads in both directions
Application examples: gear boxes, pumps, compressors, etc.
