Material and process

Material ：Black NBR nitrile rubber, full metal case, garter spring Structure ：TB type metal‑cased rotary shaft skeleton oil seal Key properties ：Oil & grease resistant, mud‑proof, anti‑vibration, anti‑aging Working temperature:‑20℃ +120℃ Manufacturing features Metal shell and rubber lip firmly vulcanized together, stable performance under chassis bumping vibration. Precision‑formed sealing lip with garter spring maintains consistent radial pre‑load pressure. NBR compound compatible 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 ：ID115mm × OD145mm, overall thickness14mm Compatible media ：Axle gear‑oil, wheel‑hub bearing grease, general chassis lubricants. Fit application ：Heavy‑duty commercial‑vehicle axle‑hub shaft sealing. Buyer reminder ：This is aftermarket replacement spare part for vehicle axle‑hub. Please verify shaft dimension, housing bore and seal profile before placing order. Dimension mismatch will result in lubricant leakage after installation.

Selection guide

Selection Tips 1. Confirm dimension ID115mm, OD145mm, thickness14mm 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 axle 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 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.
