Characteristics
PPY-Packings are high wear resistant piston packings for miniature cylinders. Higher durability and desirable friction properties are obtainable comparing with O-rings.
Remarks
- ●The material of PPY 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.
