Product details

Brand‑new aftermarket flange bowl‑style differential shaft oil seal 85x150/169x13.5/33mm, built with reinforced deep‑drawn bowl‑shaped metal shell and NBR double‑lip with garter spring, designed for heavy‑duty truck differential pinion shaft assembly. The unique bowl‑flange shell provides stable interference fit for truck axle housing bore. Pre‑loaded garter spring maintains constant radial pressure on rotating shaft. It locks differential gear‑oil inside housing and resists heavy mud, sand and splash‑water intrusion in tough off‑road and highway truck operating scenarios. Ideal for truck repair shops, heavy‑parts wholesalers and cross‑border bulk procurement. Core functions Gear‑oil retention: Stop differential gear‑oil leakage under heavy load, vibration and shock from truck driving Heavy‑duty contamination exclusion: Block thick mud, road grit and splash‑water for poor‑road truck working environment Reinforced bowl‑shaped metal shell: Anti‑rust coating, anti‑deformation for heavy‑truck press‑fit installation Garter‑spring pre‑load: Stable sealing performance under large temperature swings and continuous vibration

Material and process

Material ：NBR nitrile rubber sealing lip, anti‑rust painted deep‑draw carbon‑steel bowl‑flange shell, stainless steel garter spring Structure ：Flange bowl‑type double‑lip rotary shaft oil seal Key properties ：Oil‑resistant, heavy‑dust‑proof, anti‑vibration, anti‑aging, impact resistant Working temperature:‑20℃ +120℃ Manufacturing features High‑temperature vulcanization bonding between rubber lip and bowl‑shaped metal shell, resist rubber‑metal separation under heavy truck vibration. Precision‑ground sealing lip to reduce friction heat and extend service‑life under long‑time continuous rotation. Anti‑rust painted bowl‑flange shell adapts to harsh heavy‑truck under‑carriage environment. NBR compound compatible with heavy‑duty truck differential gear‑oil. Upgrade option ：FKM fluoro‑rubber variant for higher‑temperature heavy‑load operating conditions.

Application and compatibility

Product Type ：Bowl‑flange differential pinion shaft oil seal for heavy‑duty truck Key dimension ：ID85mm × OD150/169mm × dual width13.5/33mm Compatible media ：Heavy‑duty truck differential gear‑oil. Working conditions:Heavy‑truck differential pinion shaft, withstand heavy load, strong vibration, mud and splash‑water. Not suitable for ：Strong corrosive solvents, extreme ultra‑high‑temperature special‑purpose equipment. Fit applications ：Aftermarket replacement seal for heavy‑duty truck differential repair. Buyer reminder ：This is aftermarket replacement truck spare part. Please verify shaft diameter, housing bore and flange profile before placing order. Mismatched dimension or housing profile will cause gear‑oil leakage right after installation.

Selection guide

Selection Tips 1. Confirm dimension ID85mm, OD150/169mm, dual width13.5/33mm and bowl‑flange seal structure. 2. Standard NBR version for regular heavy‑truck gear‑oil environment; choose FKM upgrade for high‑temperature heavy‑load scenarios. 3. Inspect truck differential pinion shaft and housing bore before installation; repair shaft wear, corrosion and burrs. Damaged mating surfaces will trigger premature oil‑seal leakage. Installation Steps Preparation Fully clean differential housing bore, flange seating surface and pinion shaft, remove old seal fragments, grease dirt and metal burrs. Pre‑lubrication Coat sealing lip and shaft surface with matched heavy‑duty differential gear‑oil. Dry installation is strictly forbidden; dry friction will burn sealing lip quickly. Orientation Confirmation Main sealing lip points toward gear‑oil cavity; outer dust lip faces outward. Wrong installation direction leads to oil leakage and lost mud‑proof protection. Vertical Press‑fit Use dedicated press‑sleeve tool to press bowl‑flange oil‑seal evenly and vertically. Never strike rubber lip or thin bowl‑flange directly, to avoid shell deformation and lip tearing. Seating Inspection Ensure full flat contact between seal flange and housing seating surface, no tilt or gap. Visual Check Examine sealing lip for invisible nicks and bowl‑shell deformation; tiny hidden damage will cause seepage after commissioning. Rotation Test Manually rotate pinion shaft assembly to confirm smooth rotation without abnormal binding resistance.
