Piston head, CNC metal, with bearing, Dual Ring, SHS

Piston head, CNC metal, with bearing, Dual Ring, SHS. CNC metal piston head Dual Ring with High Flow holes, double o-rings and bearings from SHS (ref. PPS). Precise tight metal head resistant to strong impact made on precision CNC machines from one piece of high-strength 6061-T6 aluminum. Low weight warrants the smooth running of a large number of precisely spaced holes with High Flow for the impact surface optimally enhance performance. The second o-ring (thinner) has no tightening function, but only the center head with a piston in a cylinder. Piston head is from this reason precisionly through by center of the cylinder and there is thus no danger of scratching of his wall. Bearing on the piston head prevents undesirable twisting of spring. The ideal function is guaranteed in the combination with spring guide, which has bearing. Unbeatable price/performance ratio.
