Angular contact ball bearing speed limit, at the same time bear the same radial loads and axial loads, but also pure axial loading. Under the axial load capacity of the decision by the contact angle and with the contact angle increases.

Single row angular contact ball bearings

Single row angular contact ball bearings can withstand the radial and axial load. Although this type of bearing can only afford a one-way axial load, but with another bear the load reverse bearings used in combination. Angular contact ball bearings can not be a split. Angular contact ball bearings for high speed, automatic aligning capacity is very limited.

Single row angular contact ball bearings basic types

72B and 73B-FAG single row angular contact ball bearings for the contact angle of 40 °, so it can withstand a lot of axial load.

Tolerance:

72B and 73B-FAG single row angular contact ball bearings according to the general manufacturing tolerance (tolerance level of PN, no suffix)

Cage

Most of angular contact bearings with glass fiber by 66 before the nylon-made cage (suffix TVP). This cage can be below 120 ℃ temperature stability of the work of the occasion. If the use of oil-lubricated bearings, lubricating oil additives in the cage may affect the life and a high temperature, aging of the oil will shorten the life of the cage, to strictly abide by the Huanyouzhouqi. The use of machining brass cage of the angular contact ball bearing oil suffix MP.

Allow speed

Appropriate working conditions, the speed of the bearing is likely higher than the reference speed, but can not be higher than the value of the speed limit. In the heat to allow the development of speed, they should take full account of the special working environment. If the angular contact ball bearings directly side-by-side installation of special measures to be taken in order to achieve a single high-speed bearings.

Heat Treatment

FAG angular contact ball bearings after heat treatment can be no higher than 150 ℃ working temperature. 240mm in diameter than the outer ring of bearings can be no higher than 200 ℃ working temperature. If the use of nylon cage, the bearings allow the temperature to be maintained by the material plane.

General structure

The general structure of the single row angular contact ball bearings often used in pairs, are arranged in the form of: X-type (face-to-face arrangement), O-(back-to-back arrangement) and T-type (arranged in series). Also have the option to adjust the following types:

UA X and O-axial arrangement of reducing the clearance
UO X and O-type layout in zero axial clearance
Small axial clearance and zero axial clearance is the installation of non-state, will bear paired with the installation of the bearing axial clearance to reduce, or pre increased. General Bearing structure of the order, please inform the number of individual bearings, rather than the number of bearings and bearing a number of groups.
