This self-aligning ball bearing accommodates shaft misalignment through its spherical outer raceway, allowing the outer ring to pivot relative to the inner ring without inducing additional loads. The 1317-M has a bore diameter of 85.0 mm, an outside diameter of 180.0 mm, and a width of 41.0 mm, with a net mass of 5.208 kg. It is fitted with a solid brass cage (M) and features a cylindrical bore (Z). The limiting speed is 5800 1/min, with a reference speed of 4300 1/min. The radial internal clearance corresponds to CN (Group N), suitable for standard mounting conditions without preload requirements. The solid brass cage provides stability at the stated speed range and supports smooth ball guidance under continuous operation. The self-aligning design makes this bearing suitable for applications where shaft deflection or housing misalignment must be compensated without transmitting bending stress to the bearing itself.
