Angular Contact Ball Bearings

single row

Single row angular contact ball bearings feature angular raceways of inner and outer ring and a resulting force-transferring contact angle. Due to this, an axial load always induces a radial load and the other way around, which is why angular contact ball bearings are always combined with a second bearing. Paired, they canalso absorb axial and combined forces and are particularly suitable for high speeds. Single row angular contact ball bearings cannot be disassembled.

Suitable for very high speeds

Dimensions and Tolerances

The boundary dimensions of the bearings are standardised in ISO 15, DIN 616, and DIN 628-1. ALPHA Wälzlager GmbH supplies angular contact ball bearings with normal tolerance (PN) in accordance to DIN 620-2 and ISO 492. Please contact our technical department to check the availability of bearings with improved accuracy class or special tolerances.

Internal Clearance and Preload

Angular contact ball bearings are divided into clearance classes and preload classes. These are not standardised and are defined by suffixes.
