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.
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
