Oil Seals

Radial lip seals that retain oil or grease between rotating and stationary parts and help exclude contaminants.

Overview

An oil seal, or radial shaft seal, typically combines an elastomer sealing lip, metal reinforcement, and a garter spring that stabilizes lip contact. The primary lip retains lubricant while an auxiliary dust lip can improve contaminant exclusion. Material and design selection depends on temperature, chemical compatibility, speed, pressure differential, shaft hardness and finish, runout, and misalignment.

Applications

Gearboxes and transmissions
Pumps, engines, and electric motors
Conveyor pulleys and heavy equipment
