81965030333 Cassette Radial Shaft Seal 132×172×12WD-

Genuine MAN cassette radial shaft seal (132×172×12 mm, WD-type) for driveline applications. This two-part cassette design integrates the primary sealing lip, dust exclusion lip, and a pressed-steel outer housing in a single assembly, simplifying installation and reliably ensuring correct lip orientation — a critical factor in radial seal performance. Fitted at rotating shaft exits in rear axle differentials, gearboxes, and transfer cases to retain gear oil and exclude road contamination including water, mud, and abrasive particles. The 132 mm bore suits a specific shaft diameter in MAN TGA, TGX, and TGS driveline assemblies — confirm fitment before ordering. Oil leaks at shaft exits cause gear oil level depletion, contamination of brakes if fitted near the axle ends, and eventual component seizure if undetected. Cassette seals must be pressed squarely into the housing bore to the exact specified depth using the correct installation sleeve — incorrect depth or misalignment causes immediate lip damage. Never reuse a removed seal.
