Bearing Piston Head for Cyma SVD – FPS Softair

FPS Softair bearing piston head designed for the Cyma Dragunov SVD mechanism, with a filled nylon head and metal parts in Ergal and stainless steel. The thrust bearing lets the spring rotate during compression and reduces stress on the air system: a 100% made in Italy upgrade dedicated to this replica.

Operation

Under compression the spring tends to twist: the thrust bearing absorbs this torsion, so the spring works more evenly and the piston and spring guide are put under less stress. The filled nylon head is lighter than an all-metal head, while the Ergal screw retainer and bearing holder ensure a solid fit on the piston.

Installation

It is fitted to the SVD piston in place of the stock head after opening the gearbox, using the stainless steel screw provided. It is also the right time to check the seal between piston head, cylinder and cylinder head.
