A brief introduction of the comparison between the Glyd Ring and the step seal graphic
With the continuous improvement of sealing technology and the expansion of the application range of hydraulic cylinders, the working pressure of hydraulic cylinders is gradually increasing, and the requirements for the performance of seals are also increasing. The use of seals has gone through the process from simple O-rings, V-seals to complex Yx seals, U-seals and combined seals. Among them, the combined seals have excellent sealing performance and structural characteristics. , Deeply trusted and loved by hydraulic cylinder designers. This article focuses on the current combination of hydraulic seals widely used in design and excellent sealing performance-Glyd ring and Step seal.
The Glyd ring is composed of a rectangular ring of highly wear-resistant polytetrafluoroethylene composite material and an O-shaped rubber sealing ring. The O-ring provides sufficient sealing force to compensate for the wear of the rectangular ring. Used in conjunction with the guide support ring, split grooves should be used for specifications with a bore less than 40. It is suitable for hydraulic cylinder piston sealing and can be sealed in both directions. As shown
Glyd ring
The working pressure of the Glen ring: 0-40MPa up to 60MPa
Gleyd circle reciprocating speed: 5m/s
Gleyd circle swing or rotation movement: 3m/s
Grayd ring operating temperature: -40-200 (depending on the material of the O-ring)
Grayd ring applicable media: hydraulic oil, steam, water, emulsion, etc.
The step seal is composed of a step ring and O-shaped rubber sealing ring. The O-ring provides sufficient sealing force and compensates for the wear of the stepped ring. Suitable for sealing of hydraulic cylinder piston rod. As shown
step seal
The working pressure of step seal: 0-40MPa up to 60MPa
step seal reciprocating speed: 5m/s
Step seal swing or rotation movement: 3m/s
The use temperature of the step seal: -40-200 (depending on the material of the O-ring
Applicable medium for step seal: hydraulic oil, steam, water, emulsion, etc.
