Product Specifications

Note: The exact dimensions, contact angle, preload, material, lubrication, and load ratings should be confirmed against the approved product drawing and technical specification before ordering.

Key Features

• Precision P5 Manufacturing: Designed for applications requiring accurate rotation and dimensional consistency.

• Matched Bearing Configuration: DB matched arrangement can provide axial load support in both directions when correctly installed.

• Stable Operation: Manufactured with a focus on smooth running performance and consistent quality.

• Customized Solutions: Bearing dimensions, internal design, preload, and other requirements can be discussed according to application conditions and customer drawings.

Application: Crankshaft Assemblies

Angular contact ball bearings can be used in precision crankshaft assemblies where axial positioning, rotational accuracy, and reliable operation are important.

The selection of a suitable bearing arrangement depends on the applied radial and axial loads, operating speed, installation space, lubrication, and required service life.
