NJ321-C4
The NJ321-C4 is a cylindrical roller bearing with 105mm bore diameter, 225mm outside diameter, and 49mm width. This single-row bearing features C4 internal radial clearance, which is greater than C3 clearance, providing increased operating clearance for applications with thermal expansion or shaft deflection.
Cylindrical roller bearings are designed for high radial load capacity and are commonly used in electric motors, gearboxes, pumps, and machine tool spindles. The NJ-type design includes an inner ring with two integral guide ribs and an outer ring with one rib, allowing limited axial displacement in one direction.
