The RBC Bearings B40SA is a spherical plain angular-contact bearing designed for single-acting, unsealed operation. It features a 2.5000 in bore and a 3.9375 in outer diameter, enabling a precise, compact fit in rotational joints. As part of RBC's spherical plain bearing family, the B40SA supports angular movement in pivot joints where alignment between components may vary, making it suitable for industrial machinery that require reliable articulation in constrained spaces.
