TC170-190-15 / TC170x190x15 / TC17019015 Oil Seal , 170*190*15 Rubber Seal

TC170-190-15, TC170x190x15 and TC17019015 are three identical coding formats for the same TC type double-lip skeleton rotary oil seal with unified dimension 170×190×15mm. TC structure features full rubber coated outer metal skeleton, built-in garter spring reinforced primary sealing lip plus auxiliary dust lip, realizing dual functions of internal lubricant retention and external dust/moisture blocking at the same time. The fully rubber wrapped outer diameter provides good compensation for thermal expansion of aluminum alloy and plastic housings, avoiding housing corrosion and assembly gap leakage compared with TB exposed metal shell seals. Standard material is wear-resistant NBR nitrile rubber, high temperature corrosion-resistant FKM fluororubber optional for harsh working conditions. Widely matched for heavy machinery gearboxes, vehicle rear axles, large hydraulic pumps, mining equipment rotary shafts and agricultural machinery transmission assemblies, universal replacement sealing part for industrial equipment overhaul.

Full technical dimension drawings, material performance test reports and machinery fitment list available upon request

• Three model codes fully interchangeable, same dimension, structure and sealing performance, only difference is digital separator marking for different brand catalog standards
• TC full rubber coated outer shell design: excellent static sealing, offsets housing thermal expansion, allows larger housing surface roughness, effectively prevents outer circle corrosion and oil seepage
• Double lip integrated structure: spring-tensioned main lip stably retains gear oil/lubricating grease; secondary dust lip blocks sand, water vapor, metal powder to protect main lip from abrasion, greatly extend seal service life
• Two mainstream rubber material options: cost-effective NBR for normal temperature general machinery; FKM fluororubber for high temperature, chemical corrosion heavy-duty equipment
• Precision ground sealing lip with low radial contact force, reduces shaft friction loss, avoids shaft surface wear and abnormal leakage during long-time continuous rotation
• Integral steel skeleton provides stable structural support, no deformation during press-fit installation, convenient disassembly and replacement during equipment maintenance
• Support custom hardness rubber, stainless steel skeleton, OEM laser marking, neutral independent anti-dust packaging for global heavy machinery spare parts distributors
