Product Description
SKF BA1B311576 angular contact ball bearing. Single-row angular contact ball bearing configured to take combined radial and one-direction axial load. Contact angle 15°, 25°, 30° or 40° per suffix (BE / BEP / BECBP execution). Two bearings are commonly mounted in an opposing pair (back-to-back, face-to-face or tandem) so the pair carries axial load in both directions and takes moment load. Manufactured to ISO 492 Class Normal. Bore diameter d = 380 mm per ISO 15.
