SKF 21103 – Radial Shaft Seal with Metal Case and WAVE Lip

Product Description

The SKF 21103 radial shaft seal is engineered for oil or grease applications, providing reliable sealing performance between rotating and stationary components. Built with a metal case, an SKF WAVE lip for higher pumping efficiency, and a garter spring for optimal shaft sealing, this seal is designed to reduce heat generation and extend service life. Most seals also feature the SKF Bore Tite coating, ensuring a tight fit by filling small imperfections in the housing bore.
