NJ307-C4 Cylindrical roller bearing 35x80x21mm C4

The NJ307-C4 is a single row cylindrical roller bearing with a 35mm bore diameter, 80mm outside diameter, and 21mm width. This NJ-type design features high radial load capacity with inner ring guidance and is separable for simplified mounting. The C4 internal clearance provides greater radial clearance than standard, suitable for applications with thermal expansion or shaft deflection.

Cylindrical roller bearings are commonly used in electric motors, gearboxes, machine tool spindles, pumps, and industrial transmissions where high radial loads and moderate speeds are present. The separable design allows the inner ring and roller assembly to be mounted independently from the outer ring.
