85x115x12mm TG Outer-Rib Double-lip NBR Automotive Shaft Oil Seal

This aftermarket replacement TG outer‑rib double‑lip oil seal is dimensioned 85×115×12 mm, brown NBR nitrile rubber, metal‑cased construction with circumferential external ribs on outer diameter. TG rib‑shell structure greatly increases static friction inside housing bore, effectively prevents seal spinning caused by vehicle vibration and thermal expansion, especially suitable for automotive aluminum alloy housing assemblies. Built‑in garter spring and double‑lip configuration: primary sealing lip retains gear oil / lubricant, secondary dust lip blocks mud, water, grit and road contaminants. This metric standard TG‑size is widely applied for automotive rear axle, differential, transmission output shaft and general industrial reducers. No universal public OE cross‑reference number for this standard dimension, applied as aftermarket replacement seal for matching‑size vehicle assemblies. Targeted at automotive spare‑parts importers, wholesalers and vehicle repair workshops. Send inquiry including dimension, material specs, quantity and destination for formal quotation, lead time 7‑15 working days. Features & Benefits ‑ TG external ribbed outer shell: anti‑rotation performance under vibration and temperature cycling, ideal for automotive aluminum housings ‑ Double‑lip profile: main lip for oil retention, auxiliary lip for dust‑proof & mud‑proof protection ‑ Integrated garter spring maintains stable lip contact pressure absorbing minor shaft run‑out ‑ NBR nitrile rubber offers reliable performance against mineral‑based gear oils and greases for automotive working conditions ‑ Vulcanized bonding between rubber and cold‑rolled steel skeleton, stable metal‑cased structure ‑ Aftermarket cross‑replacement part for matching‑dimension TC‑type oil seals ‑ Custom logo, packing and material upgrade options available upon RFQ ‑ Suited for bulk stocking and automotive repair‑network replenishment Material & Process Sealing lip ：NBR nitrile rubber; Reinforcing skeleton: cold‑rolled steel; Garter spring: carbon steel. Vulcanized bonded construction. Typical operating temperature range:‑30℃ +100℃, max allowable working pressure ≤0.3 bar. FKM / HNBR material upgrade for high‑temperature harsh working scenarios available subject to quotation. Applications & Compatibility Primary automotive applications: vehicle rear axle, differential assembly, transmission output shaft; also fits general‑purpose industrial reducers and motor shafts with matched dimension. Works well with automotive gear oils and greases. Not suitable for strong polar‑solvent media. Aftermarket replacement part. Verify shaft OD, housing bore ID and seal width before placing order, dimension mismatch or worn housing will cause leakage risk. Selection & Installation Selection Tips 1. Confirm dimension: shaft 85 mm, housing bore 115 mm, seal width 12 mm; 2. TG outer‑rib structure is preferred for aluminum alloy housing under vehicle vibration; cast‑iron housing also compatible; 3. Confirm rubber compound according to actual working temperature and lubricant medium. Installation Steps 1. Thoroughly clean shaft and housing bore, fully remove burrs, metal chips and old‑seal residual; 2. Apply compatible lubricant to sealing lip; strictly forbid dry‑installation; 3. Install orientation: spring‑loaded lip faces towards oil‑filled cavity; 4. Adopt dedicated installation tool, apply uniform vertical press‑in force, forbid skew installation; 5. Never strike rubber lip area directly with hammer; 6. Press seal fully seated against housing shoulder; 7. Manually rotate shaft after installation to verify smooth free‑movement. Packaging & Delivery Neutral poly‑bag inner, export carton outer. Carton packing quantity adjustable. Lead time 7‑15 working days. Sample and mixed‑size orders accepted. Payment terms & Incoterms confirmed in formal quotation. Documents available upon request: commercial invoice, packing list, certificate of origin.
