Product detailed description

The SKF 71920 CDGA/P4A is a super-precision, high-capacity single-row angular contact ball bearing engineered for demanding applications. It is designed to accommodate both radial and axial loads acting simultaneously, with the axial load acting in one direction only. This bearing is universally matchable, allowing for effective load sharing when used in pairs or sets, without the need for shims or similar devices.

Key Features:

• High Running Accuracy: Manufactured to ISO tolerance class P4A, ensuring very high running accuracy.

• High Load Carrying Capacity: Designed to accommodate heavy loads at relatively high speeds under low to moderate operating temperatures.

• Universally Matchable: Can be used together in arrangements to provide effective load sharing within a predetermined preload range.
