Product Introduction
70 Shore A NBR skeleton oil seals are metal‑rubber composite radial lip‑type rotary‑shaft sealing spare parts. Manufactured by compression vulcanization and composite assembly, sealing compound is nitrile butadiene rubber with hardness 70 Shore A. Equipped with metal shell and stainless‑steel garter spring to maintain stable lip radial pre‑load. Multiple structures including TC, TB, TA, SB single‑lip and double‑lip versions are available. Featuring good oil‑resistance, wear‑resistance and low compression‑set, operating temperature‑30℃‑110℃. It effectively retains lubricating grease and mineral oil, while blocking dust, splash‑water and grit from entering rotary‑shaft assemblies. Widely used for automobile transmissions, wheel hubs, gearboxes, agricultural machinery, hydraulic pumps and general‑industrial rotating‑shaft equipment. Mass metric and inch standard sizes are kept in stock. Custom dimension, rubber hardness and OEM part‑number marking are supported per drawings or samples for aftermarket repair and OEM supporting projects.
