Product Description
What are oil seal springs?
Oil seal springs, commonly called garter springs, are close-wound extension springs joined into a continuous ring. They apply uniform radial tension around a sealing lip so the lip remains in controlled contact with a shaft or rotating surface.
Working Principle
How this spring type works.
The connected spring is installed inside the seal lip and stretched around its circumference. Its tensile force creates an even inward radial load that compensates for lip wear, temperature changes, material relaxation, and small shaft variations during operation.
