This barrel roller bearing accommodates radial loads while allowing angular misalignment between shaft and housing through its curved raceway design. The 20316-MB has a bore diameter of 80.0 mm, outside diameter of 170.0 mm, and width of 39.0 mm, with a net mass of 4.571 kg. Main dimensions comply with DIN 635-1. The limiting speed is 3950.0 1/min, and the bearing is fitted with a machined brass cage (MB) and a cylindrical bore (type Z). The radial internal clearance falls within the CN (Group N) range, suitable for standard mounting conditions without preload. The barrel roller design compensates for shaft deflection and misalignment, making this bearing suitable for applications where housing and shaft alignment cannot be guaranteed to close tolerances. Lubrication and sealing arrangements are to be selected separately according to operating conditions, as no integrated sealing is specified for this variant.
