Characteristics
PGY-Packings are high wear resistant piston packings and provide stable sealing performance under conditions: lubricated, non-lubricated and dry air systems.
Remarks
- ●The material of PGY packing has changed from NBR (RN713) to NBR (RN729), but other materials are also available. Please contact us individually.
- ●Packings should be installed in the direction specified on the above schematic.
- ●Consider adopting split grooves if one-piece groove is technically adverse.
- ●φD H9/f8 would be modified according to the variation of the bearing structure. For applications installed in combination with wear rings, refer to the dimension table of the applicable wear rings.
- ※ JIS standard sequence of surface roughness symbols refer to HERE.
