RGY Hydraulic Seal– Piston & rod packings
The grooves of RGY piston packings and RNY rod packings are compatible with those for the SKY-packings. RGY-packings are designed to withstand back pressure and provide longer service time by adopting an improved wear-resistant material.
RNY rod packings are designed exclusively for sealing rods. RNY rod packings made of a highly elastic compound achieve good sealing performance against eccentric movements.
- Packings should be installed in the direction specified in the above schematic.
- Consider adopting divided 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 together with wear rings, refer to the dimension table of the applicable wear ring.
- For information on preferred values of surface finish (roughness).
- Orders and inquiries are accepted on part numbers.
- Packings with the part numbers in the blue background are stock items.
- Packings with the part numbers including letter B are the improved strength types and incompatible with the groove of SKY-Packings.
- Packings are adequately packaged for optimum storage. Refer to “Cautions” in page 2 for the handling and the storage.
- Both in-house stock and manufacturing tooling availability of items specified in the column “Compatible SKY-Packings” can be referred in pages 26～29, SKY-Packings.
★ Inquiries for HNBR materials :
- Please specify material code RP903 or RP902 in addition to the standard part number.
- RP903 is applicable to high temperature operation and to water polyglycol operating fluid.
- RP902 is the material applicable to both high and low temperature operating conditions.
- All HNBR products are manufactured on a made-to-order basis.
- Engraved marks may be variant because some dimensions/items are manufactured by using toolings for different materials.
