Sakagami PPD Pneumatic Seal
PPD-packings are double-acting piston packings compatible with the grooves for the PSD-packings. The sealing performance of PPD-packings sustains unchanged despite large eccentric movement of the pistons. Moderate durability and fair friction characteristics.
- Basic cylinders
- Miniature cylinders
- Thin type cylinders
- Cylinders for specific requirements
- Consider adopting divided grooves if the 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 applications with bar diameterφ40 and smaller sizes, the tolerance of G dimension is altered to achieve better performance
- For information on preferred values of surface finish (roughness)
