Overview

SKF CR30003 Rotary Shaft Seal reduces lubricant leakage and contamination ingress around rotating shafts. It is a small but critical component used near bearings, gearboxes, pumps, and motors to maintain lubrication and protect equipment life.

The seal consists of an elastic lip and reinforcement or outer support structure. The lip contacts the shaft surface to provide sealing, with single-lip, double-lip, and low-friction variants selected by speed and contamination level.

Key features

Reduces lubricant leakage
Helps block dust and moisture ingress
Protects bearing service life
Fits compact mounting spaces

Typical applications

Gearbox output shafts
Pump and motor shafts
Needle bearing adjacent positions
Small industrial rotating equipment

Selection guidance

Verify shaft diameter, outside diameter, width, lip design, material, speed, temperature, and lubricant type.
