Product details

This TB‑style metal‑cased skeleton oil seal dimension 130×155×20 mm is brand‑new aftermarket replacement part for heavy‑duty commercial vehicle axle‑hub and differential shaft. Adopts rigid full‑metal outer shell bonded with NBR rubber sealing lip and built‑in garter spring. Effectively retain gear oil or bearing grease inside axle‑hub assembly, avoid lubricant leakage under heavy‑load vibration. Block sand, mud, dust and splash‑water from invading bearing and gear chamber. Widely used for vehicle repair workshops, domestic auto‑parts wholesale and cross‑border commercial‑vehicle‑parts export business. Core functions Prevent axle‑hub gear‑oil and bearing‑grease leakage under heavy‑duty driving vibration Isolate shaft assembly from mud, grit and splash‑water contamination Rigid metal‑cased structure ensures stable positioning and press‑fit installation Reliable sealing performance for long‑haul heavy‑duty transportation

Material and process

Material ：NBR nitrile rubber, full metal case, garter spring Structure ：TB type metal‑cased rotary shaft skeleton oil seal Key properties ：Oil‑resistant, wear‑resistant, dust‑proof, anti‑vibration, anti‑aging Working temperature:‑20℃ +120℃ Manufacturing features Firm vulcanization bonding between metal shell and rubber lip, 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 gear‑oil and bearing grease. Upgrade option ：FKM fluoro‑rubber variant for higher‑temperature heavy‑load working scenarios.

Application and compatibility

Product Type ：TB metal‑cased skeleton oil seal for heavy‑duty commercial vehicle Key dimension ：ID130mm × OD155mm, overall thickness20mm Compatible media ：Axle gear‑oil, wheel‑hub bearing grease, general chassis lubricants. Fit application ：Heavy‑duty commercial‑vehicle axle‑hub and differential 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 ID130mm, OD155mm, thickness20mm and TB metal‑cased 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 metal 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 metal‑shell side faces outward. Wrong installation direction leads to lubricant leakage and poor contamination‑resistance. Vertical Press‑fit Use dedicated press‑sleeve tool to press metal‑cased oil‑seal evenly and vertically. Never strike rubber lip or metal shell 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 ：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.
