Core functions Prevent rear axle gear‑oil leakage under heavy‑duty driving vibration Isolate hub bearing from mud, grit and splash‑water contamination Combination multi‑lip structure for dual‑effect sealing of oil retention and dust proof Reliable sealing performance for long‑haul heavy‑duty transportation

Material and process

Material ：NBR nitrile rubber, garter spring Structure ：Combination cassette multi‑lip rotary shaft oil seal Key properties ：Oil‑resistant, wear‑resistant, mud‑proof, anti‑vibration, anti‑aging Working temperature:‑20℃ +120℃ Manufacturing features Integrated vulcanized composite structure, stable performance under chassis bumping vibration. Precision‑formed sealing lip with garter spring maintains consistent radial pre‑load pressure. NBR compound has good compatibility with commercial‑vehicle rear‑axle gear oil. Upgrade option ：FKM fluoro‑rubber variant for higher‑temperature heavy‑load working scenarios.

Application and compatibility

Product Type ：Combination cassette rear wheel hub oil seal for heavy‑duty commercial truck Key dimension ：ID145mm × OD175mm, overall thickness27mm Compatible media ：Rear axle gear‑oil, wheel‑hub bearing grease, general chassis lubricants. Fit application ：Heavy‑duty commercial‑vehicle rear‑axle wheel‑hub sealing. Buyer reminder ：This is aftermarket replacement spare part. Please verify shaft dimension and housing bore before placing order. Dimension mismatch will result in lubricant leakage after installation.

Selection guide

Selection Tips 1. Confirm dimension ID145mm, OD175mm, thickness27mm and combination cassette multi‑lip structure. 2. Standard NBR version for normal gear‑oil environment; select FKM upgrade for high‑temperature heavy‑load working condition. 3. Inspect shaft and hub housing bore before installation; repair shaft wear, corrosion and burrs. Damaged mating surfaces will trigger premature oil‑seal leakage. Installation Steps Preparation Thoroughly clean hub housing bore and shaft surface, remove old seal residue, dirt and metal burrs. Pre‑lubrication Coat sealing lip and shaft surface with matched rear‑axle gear‑oil. Dry installation strictly forbidden; dry friction will damage sealing lip quickly. Orientation Confirmation Main sealing lip points toward gear‑oil cavity; dust‑proof side faces toward wheel outer side. Wrong installation direction leads to oil leakage and poor contamination‑resistance. Vertical Press‑fit Use dedicated press‑sleeve tool to press oil‑seal evenly and vertically. Never strike rubber body directly to avoid seal deformation and lip tearing. Seating Inspection Ensure seal sits fully flush inside housing bore without tilt. Visual Check Examine sealing lip for nicks and seal‑body deformation; tiny hidden damage will cause seepage after commissioning. Rotation Test Manually rotate hub assembly to confirm smooth rotation without abnormal binding resistance.

Packaging and delivery

Inner package ：Individual anti‑dust poly bag for each piece to protect sealing lip from scratch. Outer package ：Reinforced export carton. Packing quantity ：Adjustable per purchase requirement.
