Material and process

Material ：NBR nitrile rubber, garter spring Structure ：TC type fully rubber‑covered rotary shaft skeleton oil seal Key properties ：Oil‑resistant, wear‑resistant, dust‑proof, anti‑vibration, anti‑aging Working temperature: 20℃ +120℃ Manufacturing features Integrated full‑rubber‑covered structure, good shock‑absorbing property for chassis vibration. Precision‑machined sealing lip with garter spring maintains stable radial pre‑load pressure. NBR material has good compatibility with commercial‑vehicle gear‑oil and bearing grease. Upgrade option ：FKM fluoro‑rubber variant for higher‑temperature heavy‑load working scenarios.

Application and compatibility

Product Type ：TC fully rubber‑covered skeleton oil seal for heavy‑duty commercial vehicle Key dimension ：ID145mm × OD175mm, overall thickness19mm Compatible media ：Axle gear‑oil, wheel‑hub bearing grease, general chassis lubricants. Fit application ：Heavy‑duty commercial‑vehicle axle‑hub rotary shaft 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, thickness19mm and TC fully rubber‑covered skeleton structure. 2. Standard NBR version for normal oil/grease environment; select FKM upgrade for high‑temperature heavy‑load working condition. 3. Inspect shaft and housing bore before installation; repair shaft wear, corrosion and burrs. Damaged mating surfaces will trigger premature oil‑seal leakage. Installation Steps Preparation Thoroughly clean housing bore and shaft surface, remove old seal residue, dirt and burrs. Pre‑lubrication Coat sealing lip and shaft surface with matched gear‑oil or bearing grease. Dry installation strictly forbidden; dry friction will damage sealing lip quickly. Orientation Confirmation Main sealing lip points toward lubricant cavity; dust‑proof side faces outward. Wrong installation direction leads to lubricant 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 shaft 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. MOQ ：Stock items no MOQ, sample order supported. Lead‑time ：In‑stock goods ship within 3‑5 working days; custom logo & export‑special‑packaging orders 30‑45 working days. Custom options ：Custom logo printing available, custom‑order MOQ≥1000 pcs. Shipping protection: Moisture‑proof, dust‑proof and anti‑collision packing to prevent deformation during transit.
