Product details

This brand‑new 80x141x12/22mm TC‑type flange differential pinion shaft oil seal matches OE reference To be confirmed. Constructed with brown NBR rubber and reinforced metal flange shell for stable press‑fit installation for heavy‑duty truck differential pinion shaft assembly. Double‑lip structure with garter spring maintains consistent radial pressure against rotating pinion shaft. It effectively retains differential gear oil inside housing and stops dust, mud and splash‑water invading differential assembly. Manufactured as aftermarket replacement part for QINGTE 440, QINGTE 398 series trucks. Suitable for auto‑parts wholesalers, repair workshops and overseas bulk procurement. Core functions Gear oil retention: Prevent differential gear oil leakage under heavy‑load truck driving vibration and shock Dust & mud exclusion: Resist sand, mud and splash‑water contamination for off‑road and harsh road conditions Reinforced flange metal shell: Anti‑rust and reliable interference fit for differential housing bore Garter‑spring pre‑load: Stable sealing performance under frequent vibration and temperature fluctuation

Material and process

Material ：Brown NBR nitrile rubber sealing lip, anti‑rust painted carbon‑steel flange shell, stainless steel garter spring Structure ：TC‑type double‑lip flange rotary shaft oil seal Key properties ：Oil‑resistant, dust‑proof, vibration‑resistant, anti‑aging Working temperature:‑20℃ +120℃ Manufacturing features High‑temperature vulcanization bonding between rubber lip and metal flange shell, resist delamination under heavy truck vibration. Precision‑ground sealing lip reduces friction heat and extends service‑life. Anti‑rust painted flange shell adapts to harsh heavy‑duty truck working environment. Brown NBR compound compatible with truck differential gear oil and axle hub grease. Upgrade option ：FKM fluoro‑rubber version for higher‑temperature working environment.

Application and compatibility

Product Type ：TC‑type flange differential pinion shaft oil seal for heavy‑duty truck Key dimension ：ID80mm × OD141mm × dual width80x141x12/22mm OE reference ：To be confirmed Compatible media ：Truck differential gear oil, wheel‑hub axle grease. Working conditions: Truck differential pinion shaft, withstand heavy load, road vibration, mud and splash‑water. Not suitable for ：Strong corrosive solvents, extreme ultra‑high‑temperature special‑purpose equipment. Fit applications ：Aftermarket replacement seal for QINGTE 440, QINGTE 398 rear axle differential housing. Buyer reminder ：This is aftermarket replacement part. Please verify shaft diameter, housing bore and OE number before placing order. Mismatch dimension will cause gear oil leakage after installation.

Selection guide

Selection Tips 1. Confirm dimension ID80mm, OD141mm, dual width80x141x12/22mm, OE number To be confirmed and seal type TC flange differential pinion. 2. Standard brown NBR for regular gear oil environment; select FKM upgrade for high‑temperature scenarios. 3. Inspect pinion shaft and differential housing bore before installation; repair shaft wear, rust and burrs. Damaged mating surfaces will lead to early leakage. Installation Steps Preparation Clean differential housing bore and pinion shaft surface thoroughly, remove old seal residue, oil dirt and metal burrs. Pre‑lubrication Coat sealing lip and shaft surface with matching differential gear oil or axle hub grease. Dry installation is strictly forbidden; dry friction will damage sealing lip. Orientation Confirmation Main sealing lip faces differential gear oil cavity; dust lip faces outward. Wrong installation direction causes oil leakage and loses dust‑proof function. Vertical Press‑fit Use proper press‑sleeve tool to press flange oil‑seal evenly and vertically. Never strike rubber lip directly to avoid shell deformation and lip tearing. Seating Inspection Ensure flange oil‑seal sits fully flush inside housing bore without tilt. Visual Check Inspect sealing lip for tears and shell deformation. Tiny invisible damage triggers seepage after commissioning. Rotation Test Manually rotate differential pinion shaft assembly to confirm smooth movement without abnormal binding resistance.

Packaging and delivery

Inner package ：Individual anti‑dust poly bag for each unit to protect sealing lip from scratch. Outer package ：Reinforced export carton. Packing quantity ：Adjustable per order requirement. MOQ ：No MOQ for stock items, sample order acceptable. Lead‑time ：Stock items ship within 3‑5 working days; custom logo and export‑packaging orders 30‑45 working days. Custom options ：Custom logo printing available, custom order MOQ≥1000 pcs. Shipping protection: Moisture‑proof, dust‑proof and compression‑resistant packing to prevent seal deformation during transit.
