Overview

SKF 4903 Needle Roller Bearing is a compact bearing designed to carry high radial load within a small cross-section. It is suitable for gearboxes, automotive transmissions, industrial links, and pivot positions where space saving and load capacity are both required.

Long, small-diameter rollers are arranged in a cage or full-complement design. Versions with or without inner rings are available, and shaft hardness and surface finish are critical when the shaft is used as the raceway.
