High Pressure Reciprocating Hydraulic Cylinder Seals

Merkel Radiamatic R37 Oil Seals-Fabric Seals

1- application
Mainly used in rolling mill and heavy machinery in the transmission part of the tensile spring to increase the sealing lip of the radial force of the rotating shaft. Application and sealing media can provide sufficient lubrication occasions, the use of temperature in 100 degrees, the use of Ding Jing rubber and Ding Jing clip cloth, the use of temperature above 180 degrees can be used for the use of fluorine rubber and fluorine rubber clip cloth.
2- characteristics and advantages
Good anti abrasion; high temperature resistance, good low-temperature characteristics; ozone resistance corrosion resistance and good climate adaptability; high wear resistance; low friction characteristics; permanent compression deformation; good elasticity.
