We counter the high demands placed on service life and precision with an innovative manufacturing process. Through a firmly bonded adhesion between the sleeve and the spring (elimination of the granulation), we achieve consistent characteristics, while significantly reducing the tolerance regarding the spring forces and the geometry of the sleeve. This facilitates the precise insertion of the spring sleeve into its installed position.
Alternatively, plastic sleeves can offer various advantages in relation to feel, sound and wear characteristics.
Matched to their application, the plastic sleeves can be optimised with additional geometrical forms (elliptical, stepped, asymmetrical, flat or square).
All types of thermoplastic material can be used for the sleeves.
