taper roller bearing feature
Tapered roller bearings have taper-formed raceways on inner and outer rings, and have taper formed rollers between raceways.
If the conical surface extension, it will eventually converge in the bearing axis on a bit.
- This kind of bearings are generally used to support combined load mainly consisting of radial load.Bearing’s axial bearing capacity by contact angle a that outer raceway point of view decision.
- The greater the angle,the axial bearing capacity is the bigger.
- Tapered roller bearings are separable bearings.
- Their rollers,cage and inner ring are called as cone and outer ring are named as cup.
- Cone and cup can be mounted respectively.
- The bearings are classified by elements as single row,double row and multiple row bearings.
