Product Detail

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.

Characteristics

High static and dynamic sealing effect;
High resistance to extrusion;
low friction, high efficiency;
no sliding start, no adhesion;
High wear resistance and high operational reliability;
HWide application temperature range and high chemical resistance, depending on the choice of material for the ring;
Easy installation.
