Wipers
Wipers provide effective protection against dust, dirt and moisture that can penetrate hydraulic systems. They make a significant contribution to the functional reliability and durability of your machines. Our wipers improve the efficiency of your hydraulic components.
Rod seals
Rod seals ensure a precise seal between the piston rod and cylinder. They prevent hydraulic fluid from escaping and protect your systems from breakdowns. Rely on our high-quality rod seals for maximum operational reliability.
Static seals
Static seals are responsible for sealing between fixed, immovable components. They prevent the leakage of liquids and the penetration of impurities into connecting elements. The choice of the right seal depends on the pressure, temperature and chemical resistance requirements.
Guide elements
The use of guide rings and guide bands ensures that pistons and piston rods are optimally guided and move stably. They provide protection against abrasion and extend the service life of the cylinders. These components are crucial for reliable and long-lasting performance.
Piston seals
Piston seals reliably seal the piston against the cylinder barrel. This prevents the medium from overflowing and unwanted pressure losses in the system. Our piston seals include grooved rings, compact piston seals, sliding rings, roof gasket sets and cup gaskets to ensure optimum sealing performance.
Rotary seals
Rotary seals are used to create a tight connection between rotating and stationary parts. They prevent leakage of liquids or lubricants and protect against the ingress of contaminants. The selection of the right seal depends on factors such as speed, pressure and operating temperature. We offer classic shaft seals and oil seals from stock.
Frequently asked questions about gaskets
What types of hydraulic seals are there?
O-rings, rod and piston wipers, oil seals (radial shaft seals), V-rings (V-seals), double seals, U-rings (U-seals), seals with support rings, flat seals, sliding seals.
What is a piston seal?
A piston seal is a critical component in hydraulic cylinders that provides an effective seal between the piston and the cylinder wall. It prevents hydraulic fluid from escaping and protects against the ingress of dirt, which improves system performance and service life.
What is a rod seal?
A rod seal is used in hydraulic cylinders to ensure sealing between the piston rod and the cylinder housing. It prevents hydraulic fluid from escaping and protects against the ingress of dirt, which improves the efficiency and service life of the system.
