110.25x145x15.6mm Cassette Oil Seal, Differential Oil Seal

This cassette‑type differential oil seal dimension 110.25×145×15.6 mm is aftermarket replacement part for heavy‑duty commercial vehicle drive axle differential.

Adopts integrated cassette composite structure with partial metal shell and built‑in garter spring. Effectively holds drive‑axle gear‑oil inside differential housing, prevents gear‑oil leakage under road vibration. Blocks mud, sand, dust and splash‑water from invading differential chamber. Widely used for vehicle repair workshops, domestic auto‑parts wholesale and cross‑border commercial‑vehicle‑parts export business.

Core functions

• Prevent differential gear‑oil leakage under heavy‑load driving vibration
• Isolate differential assembly from mud, grit and splash‑water contamination
• Integrated cassette profile for stable press‑fit installation into axle housing bore
• Reliable sealing performance for long‑distance heavy‑duty transportation

Features & Benefits

• Integrated RWDR‑KASSETTE composite cassette structure with partial metal shell, stable interference press‑fit for differential housing bore.
• NBR sealing lip with garter‑spring pre‑load design, retains drive‑axle gear‑oil and blocks mud, dust and splash‑water.
• Strict dimensional tolerance control, direct aftermarket replacement for heavy‑duty commercial‑vehicle differential.
