Hydraulic seals system is the general term that describes the sealing system which be used in moving parts (In general, reciprocating motion )of hydraulic equipment. Different types of the seals are combinated use according to special application situation. Common hydraulic seals as following:
Glyd Ring
Glyd Ring is made up of PTFE Ring and O-Ring. O-Ring provide preload, then provide compensation effect for PTFE square ring`s wear. Apply to the hydraulic cylinder piston seal, and it`s two-way sealing. In generally, guide ring will be used together.
Step Ring
Step Ring is made up of PTFE Ring and O-Ring. O-Ring provide preload, then provide compensation effect for PTFE square ring`s wear. Apply to the hydraulic cylinder piston seal, and it`s one-way sealing. In generally, guide ring will be used together.
Y-Ring
Y-Ring is made up of inner lip and outer lip, called U-Ring. The friction coefficient of Y-Ring is small, so as the sealing ring of reciprocating motion, it`s widely used in hydraulic industry.
Dust ring
Dust Ring installed on a piston-rod of a hydraulic pressure cylinder or end cover of plunger rod`s exhaust. It could prevent dust and waterlogging from entering into hydraulic cylinder effectively. Moreover, it takes assistance sealing.
Guide Ring
Gudie Ring is used in moving piston and piston rod of hydraulic cylinder, with precision guidance. It could avoid the direct contact between sliding parts and sliding parts. Meanwhile, it could bear the radial force and compensate temperature change.
