Sealing Technology: Engineering Support and Technical Data

When tearing down a hydraulic cylinder, finding severe wear on one side of a seal and minimal wear on the other is a classic red flag. However, as sealing engineers, we never recommend immediately blaming the seal itself. First, we must inspect the wear status of the guide rings (wear rings), the running surfaces of the piston rod or cylinder bore, the concentricity of the assembly, and the associated clearance gaps.

Choosing a sealing ring material that matches the hydraulic oil can improve sealing performance and extend the service life of the sealing ring.

Turning seals is an efficient and flexible technology for producing high-precision customized seals. Kroc specializes in this and provides fast service.

V-type, H-type, C-type - how to choose between three types of pan-seal springs, and a comprehensive analysis of the performance of different springs.

The load level of the hydraulic cylinder is determined based on a comprehensive assessment of pressure, temperature, contamination and other conditions. The seal selection must match the working conditions and give priority to reliability.

Correct selection of dynamic and static is crucial to leak prevention and requires comprehensive consideration based on movement mode, working conditions and material properties.
