This aftermarket replacement ZD combined composite oil seal dimension 85×120×10/20 mm, brown FKM fluororubber, composite metal‑cased assembly with outer circumferential anti‑spin ribs, equipped with double garter springs and double‑lip sealing system. ZD type belongs to heavy‑duty combined hub oil seal, different from ordinary TC/TG single‑piece skeleton seal, it adopts composite assembly structure to resist large vibration, mud splash and thermal deformation, outer ribs prevent seal spinning in housing bore under heavy‑load operation. Marking on product: 2111Y‑2. Primary sealing lip locks lubricant grease / gear oil inside hub cavity; secondary dust‑proof lip blocks mud, water, sand and road contaminants. Mainly applied for heavy‑truck wheel hub, drive axle, agricultural machinery and construction‑machinery rotary shafts. No universal cross‑reference OE number in global public database, served as aftermarket replacement component for matching‑size heavy‑duty assemblies. Targeted at heavy‑duty auto‑parts importers, wholesalers and machinery repair workshops. Send inquiry including dimension, material specs, quantity and destination for formal quotation, lead time 7‑15 working days. Features & Benefits ‑ ZD composite assembly structure: double‑spring double‑lip design, higher anti‑vibration performance than ordinary TG‑type seals, adapt to heavy‑load hub working‑condition ‑ Outer circumferential anti‑spin ribs: increase static friction with housing bore, effectively avoid seal rotation caused by vibration & temperature cycling ‑ FKM fluororubber material: excellent heat‑resistance, oil‑resistance and anti‑aging performance for heavy‑duty long‑time continuous operation ‑ Composite metal‑rubber vulcanized integration, stable shape under impact and alternating temperature ‑ Aftermarket cross‑replacement for matching‑size heavy‑duty hub seals ‑ Custom logo marking, packing and material upgrade options available upon RFQ ‑ Suited for bulk stocking of heavy‑duty vehicle & engineering‑machinery repair‑network replenishment Material & Process Sealing lip ：FKM fluororubber; Reinforcing composite metal skeleton: cold‑rolled steel plate; Dual garter springs: carbon steel. Vulcanized bonded composite assembly. Typical operating temperature range:‑20℃ +200℃, max allowable working pressure ≤0.3 bar. NBR / HNBR material downgrade/upgrade available subject to quotation. Applications & Compatibility Primary applications: heavy‑duty truck wheel hub, drive axle, agricultural machinery, construction‑machinery rotary shafts. Compatible with gear oil, lithium‑based grease and most mineral‑based lubricants. Not suitable for strong polar‑solvent media. Aftermarket replacement part. Verify shaft OD, housing bore ID and installation depth before placing order; dimension mismatch or worn housing will trigger leakage risk. Selection & Installation Selection Tips 1. Confirm dimension: shaft 85 mm, housing bore 120 mm, overall width 20 mm, effective sealing width 10 mm; 2. ZD composite seal is specially developed for heavy‑duty hub / axle with strong vibration; not suggested to replace common TC/TG single‑piece seal blindly without checking installation depth; 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 main lip faces towards grease‑filled hub 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
