Guide rings and laminated piston
Durable and wear-resistant for your systems.
Our guide rings are the ideal solution for a wide range of applications for guiding moving machine parts. They offer impressive versatility and can be used in both lubricated and non-lubricated environments. Thanks to their low friction and high wear resistance, they make a significant contribution to reducing operating costs and improving the efficiency of your systems.
The materials we use for dry-running seals and guides in piston compressors are characterized by specifically matched filler contents and offer decisive advantages.
Advantages
- Exceptionally low coefficient of friction when paired with metals and plastics
- Anti-adhesive behavior without stick-slip effect
- High elongation, so that sealing and guide rings can be fitted to one-piece pistons without any problems
- High thermal resistance: -200 °C to +260 °C
- High chemical resistance to almost all solid, liquid or gaseous media
- Resistant to ageing

Types
Guide ring with scarf joint

The guide ring with scarf joint is a widely used standard in mechanical engineering. The joint clearance allows free thermal expansion of the guide ring and thus ensures optimum performance.
Guide ring with overlapping joint

The guide ring with overlapping joint offers the advantage of virtually gap-free guidance. In special applications, they can also be used for a combined guiding and sealing function, which further increases versatility and efficiency.
Guide ring with straight joint

In the case of the guide ring with a straight joint, the joint clearance ensures unhindered thermal expansion at the respective operating temperature.
Shouldered guide ring with straight joint

The guide ring in a shouldered design is ideal for limited space conditions, as it makes optimum use of the available overall length for the guide function. This guide ring is used, for example, in narrow pistons for special pneumatic cylinders and offers an efficient solution for demanding applications.
Machine parts with laminated piston
For guiding and sliding applications, special materials can be precisely connected to machine parts, such as on pistons for reciprocating compressors. Our sliding materials are used here.
Through a special joining process and precise machining, customer-specific parts are provided with a sliding coating, resulting in machine parts that are suitable for dry running and have very tight guide tolerances.
