SPG is a compact double-acting piston seal for medium to heavy duty applications. The reinforced, thermally stable thermoplastic sealing surface
with stepped joints allows the seal to pass through the port, making it ideal for double acting telescopic
cylinders.
It consists of a bronze-filled PTFE face ring preloaded by a square-section NBR
ring. The cover ring is precision machined from a compression molded blank. Compression molding of this material
provides consistently superior physical properties compared to automated molded products. The machined face ring
has a chamfer for easy installation and the surface finish is not affected by the “orange peel” effect of the
molded product. Since only the PTFE face ring is in contact with the sliding surface, the friction is very low and
the stick-slip motion is eliminated. The width of the housing allows the designer to use a narrow width piston, but
it is recommended to install enough bearings on either side of the seal.
