N308-C4 Cylindrical roller bearing 40x90x23mm C4

The N308-C4 is a cylindrical roller bearing with a 40mm bore diameter, 90mm outside diameter, and 23mm width. This single-row bearing features C4 radial internal clearance, which is greater than C3 and provides additional clearance for applications with thermal expansion or shaft/housing fits requiring extra play.

Cylindrical roller bearings are designed for high radial load capacity and can accommodate slight misalignment. They are commonly used in electric motors, gearboxes, machine tool spindles, and pumps where radial loads are predominant and high speed capability is required.
