Single Acting - Simple
Rod seals designed for single-acting applications are engineered to provide reliable sealing in one direction. These seals are ideal for hydraulic cylinders where pressure is applied in a single direction. They are simple in design, ensuring easy installation and maintenance. Made from durable materials, they offer excellent resistance to wear, extrusion, and high-pressure conditions, making them suitable for industrial and mobile hydraulic systems.
Single Acting - Complex
For more demanding single-acting applications, complex rod seals are designed with advanced geometries and materials. These seals provide enhanced performance in high-pressure and high-speed environments. They are capable of handling extreme conditions, including temperature variations and aggressive media, ensuring long-lasting sealing solutions for heavy-duty machinery.
Square Ring Activated
Square ring-activated rod seals are designed for applications requiring robust sealing performance. The square ring design ensures a tight seal, reducing leakage and improving efficiency. These seals are ideal for hydraulic systems where space is limited, and high-pressure resistance is critical. They are commonly used in construction, agriculture, and industrial equipment.
O Ring Activated
O-ring-activated rod seals are versatile and widely used in hydraulic systems. The O-ring design provides excellent sealing capabilities, ensuring minimal leakage and optimal performance. These seals are suitable for both static and dynamic applications, offering resistance to wear, extrusion, and chemical degradation. They are commonly used in automotive, aerospace, and industrial machinery.
U Ring Activated
U-ring-activated rod seals are designed for applications requiring high flexibility and durability. The U-ring design provides excellent sealing performance, even in high-pressure and high-speed conditions. These seals are ideal for hydraulic cylinders, offering resistance to wear, extrusion, and temperature variations. They are commonly used in construction, mining, and agricultural equipment.
Double Acting - Simple
Double-acting rod seals are designed to provide sealing in both directions, making them ideal for hydraulic cylinders where pressure is applied in both directions. These seals are simple in design, ensuring easy installation and maintenance. They offer excellent resistance to wear, extrusion, and high-pressure conditions, making them suitable for a wide range of industrial applications.
Double Acting 3 Elements
Double-acting rod seals with three elements are designed for more demanding applications. These seals provide enhanced sealing performance, ensuring minimal leakage and optimal efficiency. The three-element design offers superior resistance to wear, extrusion, and high-pressure conditions, making them suitable for heavy-duty machinery and industrial equipment.
Spring Activated
Spring-activated rod seals are designed for applications requiring consistent sealing performance. The spring mechanism ensures a tight seal, even under varying pressure conditions. These seals are ideal for hydraulic systems where pressure fluctuations are common, offering excellent resistance to wear, extrusion, and temperature variations.
Pneumatic
Pneumatic rod seals are specifically designed for pneumatic systems, where they provide reliable sealing in both single-acting and double-acting applications. These seals are made from materials that offer excellent resistance to wear, extrusion, and temperature variations, ensuring long-lasting performance in pneumatic cylinders and actuators.
Mining
Mining rod seals are designed to withstand the harsh conditions of mining applications. These seals are made from durable materials that offer excellent resistance to wear, extrusion, and high-pressure conditions. They are ideal for hydraulic cylinders used in mining equipment, ensuring reliable sealing performance in extreme environments.
Packs
Rod seal packs are designed for applications requiring multiple sealing elements. These packs provide enhanced sealing performance, ensuring minimal leakage and optimal efficiency. They are ideal for hydraulic systems where high-pressure resistance and durability are critical, making them suitable for heavy-duty machinery and industrial equipment.
