Technical information on Angular contact ball bearings

Single row angular contact ball bearings

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 preloaded
• 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

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
