Product details

This 75x165x12.5/18.5 mm TC‑type flange oil seal features reinforced metal flange shell for stable press‑fit mounting. Double‑lip design with garter spring maintains consistent radial pressure against rotating shaft. It prevents lubricant leakage and blocks mud, splash‑water and dust ingress to protect bearings in heavy‑duty working conditions. Widely used for agricultural machinery, truck axle, transmission and engineering equipment. Suitable for auto‑parts wholesalers, repair shops and overseas bulk procurement. Core functions Grease retention ：Prevent lubricant leakage under heavy load Dust & mud exclusion: Resist splash‑water and harsh outdoor contaminants Flange metal shell: Anti‑rust and stable interference fit Garter‑spring pre‑load: Reliable sealing under vibration and shock

Material and process

Material ：NBR nitrile rubber sealing lip, anti‑rust painted carbon‑steel flange shell, stainless steel garter spring Structure ：TC‑type double‑lip rotary shaft flange 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 shell, resist delamination under vibration. Precision‑ground sealing lip reduces friction heat and extends service‑life. Anti‑rust painted flange shell improves storage performance in humid environment. NBR compound compatible with gear oil, hydraulic oil and chassis lubricants. Upgrade option ：FKM fluoro‑rubber version for higher‑temperature working environment.

Application and compatibility

Product Type ：TC‑type flange double‑lip oil seal for heavy‑duty equipment Key dimension ：ID75mm × OD165mm × dual width12.5/18.5mm Compatible media ：Gear oil, hydraulic oil, wheel‑hub grease. Working conditions: Heavy‑duty shaft, withstand vibration, mud and splash‑water. Not suitable for ：Strong corrosive solvents, extreme ultra‑high‑temperature special‑purpose equipment. Fit applications ：Agricultural machinery, truck axle, transmission box, engineering machinery assemblies. Buyer reminder ：This is aftermarket replacement part. Please verify shaft diameter, housing bore and dimension before placing order. Mismatch dimension will cause oil leakage after installation.

Selection guide

Selection Tips 1. Confirm dimension ID75mm, OD165mm, dual width12.5/18.5mm and seal type TC flange. 2. Standard NBR for regular oil & grease environment; select FKM upgrade for high‑temperature scenarios. 3. Inspect shaft and housing bore before installation; repair shaft wear, rust and burrs. Damaged mating surfaces will lead to early leakage. Installation Steps Preparation Clean housing bore and shaft surface thoroughly, remove old seal residue, oil dirt and metal burrs. Pre‑lubrication Coat sealing lip and shaft surface with matching gear or hub grease. Dry installation is strictly forbidden; dry friction will damage sealing lip. Orientation Confirmation Main sealing lip faces 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 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 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.
