Inele de ghidare a pistonului SKF PGR 85X79X13-A

Hydraulic guide rings are made of polymer materials and prevent metal-to-metal contact between moving parts in a working hydraulic cylinder. They accommodate radial loads, acting on the cylinder assembly, guiding the rod in the cylinder head and the piston in the cylinder bore. The special SKF hydraulic guide design provides a long service life and increases resistance to wear to cylinder surfaces.
