Sakagami RGY Seal-Piston & rod packings


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.

Note:
●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)
