TC Oil Seal 45x62x8mm NBR Double Lip with Garter Spring
Product Overview
The TC oil seal 45x62x8mm is a high-performance double lip shaft seal with garter spring, designed for reliable sealing in bearing housing applications. The primary lip with integrated garter spring maintains consistent radial contact pressure on the shaft, while the secondary dust lip prevents external contaminant ingress. Constructed with NBR rubber and a metal-reinforced case, this seal delivers excellent oil and grease retention in industrial rotating equipment.

Key Features
TC Double Lip Design: Primary sealing lip with garter spring provides excellent oil retention, while the secondary dust lip blocks dirt, dust, and moisture — ideal for bearing housing protection.
Garter Spring Retention: The integrated carbon steel garter spring maintains constant radial load on the shaft even after wear, extending seal service life compared to springless designs.
Metal Case with Rubber Coating: The stamped steel outer case with full rubber coating ensures a tight interference fit in the housing bore and prevents leakage around the OD. Rubber coating also compensates for minor housing surface irregularities.
NBR Elastomer: Nitrile rubber offers excellent resistance to mineral oils, greases, hydraulic fluids, and water — the standard choice for general industrial bearing applications.
Wide Temperature Compatibility: Operating range from -40°C to +120°C covers the majority of industrial gearbox, motor, and pump applications in both cold-start and continuous-operation conditions.
Typical Applications
Bearing housing shaft sealing for pillow block and flange units
Industrial gearbox input and output shaft seals
Electric motor bearing protection
Hydraulic pump and motor shaft sealing
Agricultural machinery gearbox and axle seals
Conveyor roller bearing sealing
General rotating equipment oil and grease retention
Why TC Oil Seals Are Essential Bearing Accessories
The TC oil seal is the most widely specified shaft seal type in the bearing industry. Unlike simple single-lip seals, the TC design combines a spring-loaded primary lip for dynamic oil retention with an auxiliary dust lip for contaminant exclusion — providing complete bearing protection in a single component. The rubber-coated OD eliminates the need for sealant during installation and ensures reliable static sealing in the housing bore. For bearing distributors and maintenance operations, stocking TC oil seals in common shaft sizes is essential for complete customer service.
