Back-up ring A401 27x32x1.3 TPE
Back-up rings made of thermoplastic material TPE are intended for installation together with O-rings to reduce the extrusion gap between metal surfaces of two cylinder components to enable the seal to operate at higher pressures without extruding and being damaged.
Piston rod guide ring A251 40x45x9.7 POM+фибростъкло
Piston rod guide rings A251 are suitable for both piston and rod applications in light to medium duty hydraulic cylinders. They are manufactured with with a standard 45 degree cut, and offer appropriate K gap value adjustment with a Z cut design, resistance to medium radial loads (up to 40 Newton/mm2), very easy snap installation, very economic bearing solution, excellent stability to operating temperatures. Suitable for use in mineral hydraulic oils.
Material: glass filled Polyacetal.
Wiper A204 16x24x4/7 NBR90
A204 wipers are designed to prevent the entry of unfavorable particles into the system of the hydraulic cylinder.
