Product Description (Clean Summary)

The FAG 7311-B-XL-JP-UA is a single row angular contact ball bearing designed to support high radial loads and axial load in one direction. Its 40° contact angle increases axial load capacity. As an X-life (XL) bearing, it features an optimized internal design and higher-quality components for higher load capacity, longer service life, and reduced heat generation, supporting higher operating speeds and longer maintenance intervals. The UA universal mounting allows pairing in O or X configurations with small axial clearance.
