Description
Spherical Roller Bearing with cylindrical bore and normal clearance
Nachi's 21307 EXQW33 is a double-row spherical roller bearing measuring 35 mm bore by 80 mm outside diameter by 21 mm width. The spherical outer raceway lets the two roller rows swivel as a unit, which means the bearing tolerates the misalignment and shaft bending that come with long drives, screening equipment and heavy conveyors without losing load capacity. Normal CN clearance suits standard fits and moderate temperature differences across the bearing. A lubrication groove with feed holes in the outer ring allows regreasing in place, and the sheet steel cage carries the roller set from -30 to +200 degrees C.
