Oil seals are high-performance sealing components designed to prevent lubricant leakage and block contaminants (dust, water, etc.) from entering mechanical systems. They are widely used in rotating shafts and bearing applications. Constructed with elastomer materials (such as NBR rubber or FKM fluorocarbon rubber) reinforced with a metal casing, they combine flexibility with durability. The lip seal design (primary lip for oil retention, secondary lip for dust exclusion) ensures long-lasting, reliable sealing performance.
Common Applications:
Bearing Seals: Electric motors, generators, automotive wheel hubs, transmissions, crankshafts.
Drive Systems: Gearboxes, reducers, universal joints, CV joints.
Industrial Equipment: Hydraulic cylinders, construction machinery (excavators), pumps, fans.
Household Appliances: Air conditioner compressors, washing machines, etc.
Key Features & Benefits:
*** Oil & wear-resistant (NBR/FKM material options)
*** Dustproof & waterproof for extended equipment life
*** ISO-compliant (e.g., TC-type oil seals)
For extreme conditions (high temperature/pressure), PTFE oil seals or mechanical seals can be used as alternatives. Proper selection depends on speed, medium, and temperature for optimal sealing performance.
