5Pcs Nitrile Skeleton Oil Seal, 65mm x 120mm x 15mm,with Excellent Oil Resistance and Wear Resistance

Upgrade your equipment's sealing performance with our premium Nitrile Rubber (NBR) Skeleton Oil Seal—the reliable solution for preventing oil leakage and blocking contaminants in automotive, industrial, and agricultural machinery. Crafted from high-quality NBR rubber, this seal delivers exceptional oil, wear, and aging resistance, maintaining elasticity and sealing integrity even with prolonged exposure to lubricants and harsh conditions. The reinforced metal skeleton ensures a secure, gap-free fit in standard housing bores, while the proven TC double-lip design with integrated spring creates a dual barrier: the primary lip locks lubricants inside, and the secondary lip blocks dust, dirt, and moisture from damaging critical components. The tensioned spring maintains consistent lip pressure for long-lasting, reliable sealing. Suitable for a wide range of applications—including automotive engines, transmissions, wheel hubs, industrial gearboxes, pumps, hydraulic systems, motorcycles, and 3D printers—this universal seal fits directly into standard shaft sizes without modification, making it ideal for routine maintenance and repairs. It operates reliably across a temperature range of -40°C to +120°C (-40°F to 248°F), withstanding high-speed rotation and high-pressure conditions. Easy to install and built for durability, our NBR skeleton oil seal reduces maintenance frequency, prevents costly downtime, and extends the service life of your mechanical components. Each seal is manufactured to strict dimensional tolerances and quality standards, ensuring a perfect fit and dependable performance for all your sealing needs.

• Crafted from high-quality nitrile rubber (NBR) with a reinforced metal skeleton, this oil seal delivers exceptional wear resistance, oil resistance, and aging stability. The robust rubber compound maintains excellent elasticity and sealing performance even under continuous friction, effectively preventing oil leakage and extending the service life of your mechanical components. Ideal for long-term use in demanding industrial and automotive environments.
• Featuring a standard TC double-lip design with a built-in spring, this radial shaft seal creates a tight, reliable barrier against oil, grease, dust, and moisture. The primary lip seals lubricants inside, while the secondary lip blocks external contaminants from entering the bearing or gearbox. The precision-machined metal core ensures a secure fit in the housing, eliminating gaps and ensuring consistent sealing performance under high-speed rotation.
• This universal NBR oil seal is suitable for a vast range of machinery and vehicles, including:Automotive engines, transmissions, axles, and wheel hubsIndustrial gearboxes, pumps, compressors, and hydraulic systems Agricultural equipment, motorcycles, and ATVs 3D printers, automation equipment, and general mechanical assemblies It is a perfect replacement part for standard shaft sizes, offering easy installation and interchangeability.
• Nitrile rubber provides outstanding resistance to mineral oils, greases, and hydraulic fluids, making this seal ideal for operating temperatures ranging from -40°C to +120°C (-40°F to 248°F). The reinforced skeleton enhances structural rigidity, preventing deformation under high pressure and ensuring stable sealing performance even in high-speed, high-load working conditions.
• Designed for hassle-free installation, this radial shaft oil seal fits directly into standard housing bores without modification. Each seal is manufactured to strict dimensional tolerances, ensuring a perfect match for your equipment. It is a cost-effective solution for routine maintenance, repair, and overhaul (MRO), helping you avoid costly downtime and equipment damage caused by oil leakage.
