Polyurethane collars. Buy online at the best price
Polyurethane collars are used in hydraulic and pneumatic cylinders for fluid sealing. They sit inside the cylinder head and seal against the cylinder rod, preventing fluid from flowing through the cylinder head.
This allows pressure to build on one face of the piston, causing the cylinder to extend or retract. Only for longitudinal movements. Its use is for single-acting cylinders. It is very common to use it in double-acting cylinders, but placing two symmetrical joints placed in opposite directions. They are flexible for placement in your accommodation.
Range of Application: Primarily for sealing pistons, cores and piston rods in light and heavy duty applications in mobile and static pneumatic and hydraulic systems. Its use is widespread in any type of industry, since pneumatic or hydraulic cylinders are commonly used in any industry.
The collars are made of 94 Shore polyurethane. The longitudinal displacement speed is 0.5 m/sec. Temperature -35ºC / 100ºC.
