65x90x12mm TG Type Outer Rib Double‑lip FKM Oil Seal Brown Shaft Oil Seal

This aftermarket replacement TG outer‑rib double‑lip oil seal is dimensioned 65×90×12 mm, brown FKM fluorocarbon rubber. TG structure features outer circumferential ribbed ribs, optimised for aluminium alloy housings with large thermal expansion, prevents seal spinning inside housing bore. Built‑in garter spring and double‑lip construction, primary lip retains lubricant, secondary lip blocks dust, mud and water ingress. Widely applied for gearboxes, speed reducers, motor shafts, diesel engine auxiliary shafts, general‑purpose high‑temperature rotary shaft equipment. No universal public OE‑number for this standard metric TG dimension, used as aftermarket cross‑reference replacement part. Targeted at industrial machinery importers, wholesalers and repair workshops. Send inquiry including size, material specs, quantity and destination for formal quotation, lead time 7‑15 working days. Features & Benefits ‑ TG outer ribbed shell: increases static friction with housing bore, effectively prevents seal rotation under vibration and thermal cycling, excellent for aluminium housings ‑ Double‑lip profile: main lip for oil retention, auxiliary dust‑proof lip blocks external dirt, moisture and grit ‑ Integrated garter spring maintains stable lip contact pressure against minor shaft run‑out ‑ FKM fluororubber delivers outstanding high‑temperature and oil‑chemical resistance ‑ Vulcanized bonding between rubber and steel skeleton, robust structure for continuous rotary operation ‑ Aftermarket cross‑replacement for TC‑type seals under matching dimension conditions ‑ Custom logo, packing and material options available upon RFQ ‑ Suited for bulk stocking and machinery repair‑network replenishment Material & Process Sealing lip ：FKM fluorocarbon rubber; Reinforcing skeleton: cold‑rolled steel; Garter spring: carbon steel. Vulcanized bonded construction. Typical operating temperature range:‑20℃ +200℃, max allowable working pressure ≤0.3 bar. NBR / HNBR material downgrade/upgrade available upon request subject to quotation. Applications & Compatibility Mainly used for industrial gearboxes, reducers, motors, diesel engine auxiliary shafts, general rotary‑shaft equipment with aluminium housing. Adapt to mineral oils, gear oils and partial chemical‑oil media. Not fit for strong polar‑solvent environment. Aftermarket replacement part. Verify shaft OD, housing bore ID and width dimension before placing order, dimension mismatch will trigger leakage risk. Selection & Installation Selection Tips 1. Confirm actual dimension: shaft 65 mm, housing bore 90 mm, seal width 12 mm; 2. TG outer‑rib structure is preferred for aluminium housing subject to temperature expansion; cast‑iron housing also compatible; 3. Confirm rubber compound according to actual working temperature and medium. Installation Steps 1. Thoroughly clean shaft and housing bore, fully remove burrs, metal chips and old‑seal residual; 2. Apply lubricant to sealing lip; strictly forbid dry‑installation; 3. Install orientation: spring‑loaded lip faces towards lubricant‑oil cavity, outer rib side fits into housing bore; 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. Send inquiry with dimension, material, quantity and destination for firm lead‑time.
