A built in carbon steel garter spring maintains consistent radial preload on the shaft surface, even under heavy load vibration and road impact. The inner lip retains hub gear oil and bearing grease inside the assembly, while the outer lip blocks road dust, mud, grit and splash water from invading the bearing chamber, extending wheel hub bearing service life. Manufactured under ISO/TS 16949 quality management system with strict dimensional tolerance control, it matches original OEM installation dimensions and can be directly fitted without modification. Produced in Hebei, China with mature supply chain, we maintain stable bulk stock to support fast delivery and large volume procurement for global aftermarket channels. Core value for global buyers Direct OEM dimension interchangeability, drop in replacement for Sinotruk Steyr axles Factory direct pricing from Chinese manufacturing base, cost effective for bulk sourcing Stable finished goods inventory, supports urgent orders and regular scheduled replenishment Consistent batch quality verified by standard automotive sealing test requirements

Selection guide
Selection Guide 1. Confirm OEM cross reference numbers WG9112340113 / WG9112340114, and verify shaft ID 190mm, housing OD 220mm, thickness 15mm and TB double lip metal case structure. 2. Standard NBR version for normal truck operating conditions ( 30℃ 120℃); select FKM upgrade for high temperature and chemically aggressive environments. 3. For fleet long term procurement projects, contact us for exclusive bulk pricing and dedicated supply schedule. Installation Steps Surface Preparation Thoroughly clean the rear hub housing bore and shaft surface, remove old seal residue, dirt, rust and metal burrs. Pre lubrication Apply matching hub gear oil or bearing grease evenly on the sealing lip and shaft mating surface. Dry installation is strictly prohibited as it will cause premature lip wear and failure. Orientation Confirmation The main sealing lip faces the lubricant cavity side; the dust proof lip faces the wheel outer side. Reverse installation will cause oil leakage and loss of mud protection. Press fit Installation Use a dedicated press sleeve tool to press the seal in evenly and vertically. Never strike the metal case directly to avoid seal deformation and lip tearing. Post installation Check Ensure the seal sits fully flush inside the housing bore without tilt or offset. Inspect the sealing lip for nicks, scratches and deformation. Function Test Manually rotate the wheel hub assembly to confirm smooth rotation without abnormal binding resistance.
