INA Bearing 81220-TV

Product description of INA Bearing 81220-TV

INA Bearing 81220-TV it belongs to INA Bearing > Roller Bearings > Axial cylindrical roller bearings,Axial cylindrical,Single-row cylindrical roller bearings with cage are units comprising solid inner and outer rings and cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or no ribs, and the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers from coming into contact with each other during rolling. Cylindrical roller bearings can be supplied with or without a cage.

Classic”cylindrical roller bearings have extremely high radial load-carrying capacity and high rigidity. In addition to high radial loads, cylindrical roller bearings can also support axial loads if they are used as semi-locating or locating bearings. Whereas radial loads are transferred via the raceways, axial loads are transferred via the rolling element end faces and ribs, which, of course, limits the axial load. This is precisely where Schaeffler gets to work!

New design and improved roller contact

The reduced surface pressure provides a number of benefits:
The permissible axial load for semi-locating and locating bearings is increased by a factor of 1.5 compared with standard bearings
Lower bearing temperatures, since the frictional torque under axial load is reduced by up to 50%
Significantly less wear on the rollers under axial load due to improved lubricant film formation
Bearings have a longer operating life under axial load

INA Bearing 81220-TV Axial cylindrical roller bearings

Axial cylindrical roller bearings have a high axial load carrying capacity, are extremely rigid and can support axial forces in one direction. Axial cylindrical roller bearings have a greater load carrying capacity than axial needle roller bearings with the same bearing diameter.

Axial cylindrical roller bearings are particularly suitable where:

high axial and shock locks occur in one direction and no radial loads are present the load carrying capacity of comparable axial deep groove ball bearings is no longer sufficient the axial space available is only very small the bearing parts can or must be mounted separately.

Designs

INA Bearing 81220-TV Axial cylindrical roller bearings are available as: complete single and double row bearings

individual bearing parts for combination, comprising axial cylindrical roller and cage assembly, housing locating washer and shaft locating washer; bearing washers can be used as an alternative to the housing and shaft locating washer) The use of complete axial cylindrical roller bearings is then advisable if, for example, high speeds occur and the bearing washers must therefore be centred precisely. If the available axial space is small, it may be helpful to integrate the axial cylindrical roller and cage assembly directly in the adjacent construction. The running surfaces for the rolling elements must therefore be produced as rolling bearing raceways.
