Garter Springs (Oil Seal Springs)

Garter springs are continuous coil springs formed by connecting both ends to create a uniform clamping force around an object.

Garter springs, also known as oil seal springs, are widely used in radial shaft seals to maintain consistent sealing pressure by keeping the elastomer lip firmly in contact with the rotating shaft. They are designed to operate reliably under varying temperatures and pressures, effectively preventing leakage and contamination.

Garter springs ensure long-term sealing performance in dynamic applications due to their flexibility and constant radial force.

Garter Springs Material

  • Stainless Steel – for corrosion resistance and extended service life

  • Carbon Steel – for standard applications requiring high strength and durability

Applications

Garter springs are used in a wide range of industries and equipment, including:

  • Hydraulic pumps

  • Washing machines

  • Engine and transmission oil seals

  • Automotive sealing systems

  • Electronic and mechanical assemblies

Working Principle

The garter spring operates by generating a radial force through its inner diameter, pressing the sealing lip firmly against the shaft surface. This constant pressure compensates for wear, shaft runout, and minor dimensional variations, ensuring reliable sealing under dynamic conditions.

This type of spring is primarily used in applications where tight contact around a rotating or reciprocating shaft is required.
