Wear rings and cushioning seals
The function of a wear ring, wear band or guide ring is to absorb the side load forces of the rod and/or the piston and to prevent metal-to-metal contact that would otherwise damage and score the sliding surfaces and eventually cause seal damage, leakage and component failure.
Wear rings should last longer than the seals as they are the only thing stopping expensive damage to the cylinder.
Our non-metallic wear rings for rod and piston applications offer great benefits over traditional metal guides:
- High load bearing capabilities
- Cost effective
- Easy installation and replacement
- Wear-resistant and long service life
- Low friction
- Wiping/cleaning effect
- Embedding of foreign particles possible
- Damping of mechanical vibrations
A complete range of seals and bearings for pneumatics including the most common dimensions for pistons and rods. The guide rings are made of a specially developed, self-lubricating plastic material to provide low friction, wear resistance, long term compression stability and excellent service life.
What are the primary functions of wear rings in hydraulic systems?
The primary function of a wear ring, also known as a wear band or guide ring, is to absorb the side load forces of the rod and/or piston. This prevents metal-to-metal contact that could otherwise damage and score the sliding surfaces, leading to seal damage, leakage, and eventual component failure.
How do wear rings compare to traditional metal guides in terms of performance?
Our non-metallic wear rings offer significant benefits over traditional metal guides, including high load bearing capabilities and reduced friction, which can enhance the overall efficiency of the system. Moreover, wear rings should last longer than seals, protecting expensive components from damage.
What materials are typically used for cushioning seals, and how do they enhance performance?
Cushioning seals are generally made from advanced materials like polyurethane and rubber compounds, which provide excellent elasticity and resilience. These materials not only improve sealing performance but also contribute to overall system efficiency by reducing wear and extending the lifespan of components.
