Product description of SKF Bearing QJ 232 N2MA

SKF Bearing QJ 232 N2MA,it belongs to SKF Bearing > Rolling bearings > Ball bearings > Angular contact ball bearings > Four-point contact ball bearings.
Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported (Load ratio). The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves. relative type you may also like SKF Bearing QJ 234 N2MA.
Both inner ring halves of SKF Explorer four-point contact ball bearings have a recessed shoulder. This improves oil flow when the bearing is used in combination with an SKF cylindrical roller bearing. In addition, these recesses can be used to facilitate dismounting.
Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.
The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.
SKF Bearing QJ 232 N2MA, The SKF standard assortment of four-point contact ball bearings includes:
Bearings in the QJ 2 and QJ 3 series
Some sizes in the QJ 10 and QJ 12 series
SKF Explorer bearings
SKF Explorer bearings
Bearings with locating slots
SKF Bearing QJ 232 N2MA, Four-point contact ball bearings can be supplied with two locating slots in the outer ring:
Preventing the bearing from turning
Positioned 180° apart
The dimensions and tolerances of the locating slots are in accordance with ISO 20515 and are listed in following.
SKF four-point contact ball bearings are fitted with one of the cages shown in there.
For additional information about the suitability of cages, refer to Cages
The permissible operating temperature for four-point contact ball bearings can be limited by:
The dimensional stability of the bearing rings and balls
The cage
The lubricant
Where temperatures outside the permissible range are expected, contact SKF.
Bearing rings and balls
The bearings are heat stabilized up to at least 150 °C (300 °F).
Cages
Steel, brass or PEEK cages can be used at the same operating temperatures as the bearing rings and balls.
Lubricants
For temperature limits of SKF greases, refer to Selecting a suitable SKF grease.
When using lubricants not supplied by SKF, temperature limits should be evaluated according to the SKF traffic light concept.
