Tapered roller bearings mainly bear combined load that are mainly from radial section and axial section. The bearing capacity depends on the angle of outside race rollaway. The angle is large the bearing capacity is large. This kind of the bearing belongs to gateless lager. According to the rows of rolling element in bearing it fall in single row, double row and four row tapered roller bearings.

Industrial application of tapered roller bearings

Tapered roller bearings apply to automobile rolling mill mine metallurgy plastics machinery etc.

The series of tapered roller bearings

30200 series, 30300 series, 32200 series, 32300 series, 32000 series, 33000 series, 32900 series

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.
