Working Principle Introduction
How WG9981340213 Sinotruk rear wheel oil seal works:
Press Installation: Oil seal is pressed evenly into the rear hub fixed groove.
Inner Lip Sealing: Primary lip closely contacts rotating axle to stop grease leaking outwards.
Outer Dust Barrier: Auxiliary lip blocks dirt and water from entering the hub interior.
Continuous Protection: Stable sealing during wheel rotation, avoid bearing damage caused by insufficient lubrication.
Actual Application Scenarios
This rear wheel oil seal performs well in various tough working conditions:
Logistics Transportation: Reduce rear axle maintenance frequency for HOWO trucks running continuous long-distance routes with full loads.
Construction & Mining: Defend against mud and splashing water on rugged mine and construction sites, protect rear wheel hub assemblies.
Export Proven: We supply this oil seal to repair garages, fleet operators and spare parts wholesalers in Central Asia and Russia. It works reliably under low temperature and high temperature climate, winning repeated orders from overseas partners.
Product Testing Standards
Every batch of oil seals goes through strict inspections before leaving the factory. We carry out dynamic rotation sealing test, high-low temperature aging test and compression deformation test. Unqualified items will be picked out directly. Strict testing helps cut failure rates after installation and brings more stable use experience for end users.
Installation Tips
Clean the axle surface and hub groove thoroughly before fitting the oil seal. Avoid sharp tools scratching the rubber lip. Press the seal evenly, do not tilt during installation. Improper operation will cause early leakage and shorten service life.
