The Reliable Guide of Axial Movement, Maximum Protection
Maintaining mechanical integrity in the harsh operating conditions of hydraulic systems directly affects the system's performance and lifespan. Rod Bearing Elements, manufactured with Sürlas Kauçuk quality, are critical guiding components that ensure the smooth, seamless, and stable movement of the piston rod in the axial direction in hydraulic cylinders.
Manufactured from specially formulated engineering polymers resistant to wear and heavy operating conditions, these elements safely absorb the lateral loads generated in the system. By definitively preventing metal-to-metal contact during dynamic movement, they protect both the piston rod and the cylinder body like a shield against friction-induced scratches and structural damage. In this way, they prevent the deformation of the main sealing elements (seals) in the system, alleviate the load on them, and significantly extend the overall service life of your hydraulic system.
Key Advantages:
Flawless Protection: Completely eliminates metal-to-metal contact, preventing mechanical damage inside the cylinder.
Stable and Steady Movement: Successfully dampens lateral forces by perfectly guiding the piston rod.
High Wear Resistance: Extends maintenance intervals and reduces costs with its durable structure that minimizes friction.
Performance Increase: Increases the overall sealing efficiency of the system by ensuring that the sealing elements operate on the most accurate axis.
