NJ307-C4 is a cylindrical roller bearing, 35 mm bore × 80 mm OD × 21 mm wide (1.378 × 3.1496 × 0.8268 in). It has C4 internal clearance.
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.
