INA Bearing 3003

Product description of INA Bearing 3003

INA Bearing 3003It belongs to INA Bearing > Ball Bearings > Angular Contact Ball Bearings, In angular contact ball bearings, the forces are transmitted from one raceway to the other at a specific contact angle (oblique to the radial plane). The bearings are therefore suitable for radial and axial loads acting simultaneously.

As the nominal contact angle increases, so does the axial load carrying capacity. As a result, INA Bearing 3003, angular contact ball bearings are more suitable than deep groove ball bearings for supporting higher axial forces.

The bearings are available in a single row design as single bearings or as a pair of universal bearings as well as in a double row design.

Single row angular contact ball bearings are particularly suitable where: bearing arrangements must support combined loads moderate to high axial loads are present on one side rigid axial guidance is required the bearing arrangement must be axially clearance-free or preload-ed high speeds are required under higher radial and axial loads.

Double row angular contact ball bearings are particularly suitable where: the design envelope is not sufficient under high loads for a pair of single row angular contact ball bearings high radial and axial loads are acting simultaneously tilting moments must also be supported a relatively rigid bearing arrangement is required.

INA Bearing 3003 Single row angular contact ball bearings are particularly suitable where:

• bearing arrangements must support combined loads, – i.e. radial and axial loads acting simultaneously • moderate to high loads are present on one side • rigid axial guidance is required • the bearing arrangement must be axially clearance-free or preload-ed • high speeds are required under higher radial and axial loads • the bearing arrangement is to run quietly in addition to meeting the requirements stated above

Double row angular contact ball bearings are particularly suitable where:

• the design envelope is not sufficient under high loads for a pair of single row angular contact ball bearings • high radial and axial loads are acting simultaneously • tilting moments must also be supported • a relatively rigid bearing arrangement is required • the bearing arrangement is to run quietly in addition to meeting the requirements stated above

INA Bearing 3003 Bearings of basic design

Comparable with a pair of single row angular contact ball bearings

Double row bearings correspond in their structure to a pair of single row angular contact ball bearings in an O arrangement, but they are narrower to a certain extent. They differ in the size of the contact angle α and the design of the bearing rings. Due to the manufacturing processes used, open bearings, which are also available with sealing washers or sealing shields, can have turned recesses in the outer and/or inner ring for sealing washers or sealing shields.

Extensive and versatile range of product variants

Bearings of series 38..-B(-2RSR, -2Z), 30..-B(-2RSR, -2Z), 32..-B(-2RSR, 2Z), 32..-BD(-2HRS), 33..-B(-2RSR, -2Z), 33..BD(-2HRS) are self-retaining. They do not have filling slots in the end faces of the bearings rings. Bearings of series 32..-BD and 33..-BD have an optimized internal construction. In design terms, double row angular contact ball bearings thus fulfil the requirements for: • supporting axial loads in both directions and high radial loads • low-noise running • versatile application
