CDK offer a seal kitting service for hydraulic cylinder manufacturers and repairers. We specify the required seals and create seal kits made to our customers’ requirements.
Hydraulic applications can be challenging for seals. Not only must the hydraulic seals completely prevent leakage of fluid from the cylinder, but they must also withstand high pressures, extreme temperatures and transverse forces within the cylinder. Hydraulic Seals go far beyond preventing fluid leakage.
Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing. They are internal to the cylinder head and seal against the cylinder bore, preventing fluid flow. This allows pressure build up on one side of the piston, making the cylinder extend or retract.
Rod seals prevent leakage of fluid from within the cylinder. Wear rings guide the piston and piston rod within the hydraulic cylinder, absorbing transverse forces, preventing metal-to-metal contact. Scrapers or wipers scrape dirt, foreign particles, chips or moisture from the piston rods as they retract into the cylinder.
We hold stock to cut down breakdown and turnaround times saving you both time and money. We also deal with all major seal manufacturers thus reducing the workload of already over stretched purchasing departments.
