Product Description

Product wave spring introduction

Wave spring has its unique advantage of saving space, which can replace coil springs. Wave spring also decreases spring cavity by reducing spring operating height. It saves cost by reducing both component size and material used in production.

Wave spring works as a force loading device. It takes up gap and compensate for dimensional changes within the assembled device. Almost any range of forces can be achieved by gradually or suddenly changing loading force to preset working length. So a precise spring ratio can be realized when loading force and deflection change in proportion.

SEALMANN introduced advanced equipments from overseas used specifically for wave spring making and pre-tempered cold rolling formed flat wire is used to produce wave springs through continuous winding process, which possesses many advantages over products made from die stamping process.

‘SEALMANN’ wave spring as a force loading component can effectively compensate for dimensional deviations in assembly and it can meet in different static or dynamic applications. There are mainly three types of wave springs, i.e. single-layer wave spring, multi-layer standard wave spring and multi-layer stacked wave spring, and they are widely used in applications such as hydraulic and pneumatic, machinery, gear drive, automobile, aerospace and petrochemicals etc.


What is the range of your wave spring applications?

Our wave spring products are widely used in Automation, Space exploration, Medical equipment, Energy, Consumer goods, Heavy duty machinery, Aerospace and aviation, Automobile.

Why choose you as our External RETAINING RINGS for Grooves in Bearings supplier?

1.Competitive prices

Provide you with the best cost performance wave springs.
25% or more saving than that of imported parts.
More competitive prices comparing with products made from the same material standard by Other domestic manufacturers.
Imported stainless steel SUS631 replaces SUS304 sourced in local market, with better cost performance.
Automatic and high-efficiency production, better price when ordered in high volume.
2.Excellent performance
SEALMANN wave springs are reliable and excellent in consistency and performance, with smooth surface, free of indentation, scratch, rupture and other minor defects, more stable elasticity coefficient within the range of deflection allowed.
Compared with single-layer stamped wave springs, standard parallel springs, Belleville springs, ”SEALMANN” wave springs have clear advantages in performance as follows,Compact structure, installation space can be saved by at least 50% for same loading Cost saving, working length can be reduced as well as the cost on material of cavity.
Noise reduction, even loading of force in mechanical transmission helps to eliminate axial run-out.
Reducing vibration, unique design of pressure compensation.

Long life, stable mechanical performance ensures excellent anti-fatigue strength.
