Agricultural Machinery Gearboxes and Power Take-Off oil seals

Industry: Agricultural

Designed for gearboxes and PTO shaft end seals in tractors, combines, balers, and other equipment, providing dust protection, resistance to agricultural greases, and ease of replacement

Agricultural machinery is highly seasonal and is often stored outdoors, so shaft ends are frequently exposed to crop straw fibers, dirt, and agricultural grease. Gearboxes and power take-off (PTO) oil seals must maintain oil retention and dust protection under low- to medium-speed, high-dust conditions.

  • Typical Applications: Transmission gearboxes, front axles, PTO output shafts, header drive shafts
  • Recommended Design: Double-lip skeleton oil seals + dust-proof secondary lip; for highly eccentric applications, enhance the match between garter spring, seal lip, and hardness (Shore)
  • Material: Primarily NBR; upgrade to HNBR/FKM when exposed to special greases or higher oil temperatures
  • Collaboration model: Stocking based on model lists; small-batch with multiple specss, OEM OEM brandingpackaging
