KDAS polyurethane piston seal , DAS polyurethane piston seal for air seal
What is piston seal
Piston seals, also known as piston packings, are mounted on a piston head which moves through the bore of a hydraulic or pneumatic cylinder tube. The inner diameter of the seal is fitted in a static housing/ groove within the piston head. Piston seals can either be single acting seals (designed for pressure from one side only), or double acting seals (designed for pressure from both sides) and are usually used in a sealing system with bearings, which are either incorporated into the seal or separately in additional housings. Sometimes single acting seals are mounted back-to-back on a piston head in separate grooves to provide a double acting arrangement.ect.
Detailed of KDAS/DAS PU piston seal information
| item name | KDAS/DAS PU piston seal |
| function | The function of a piston seal is to contain pressure on one side of a piston without leakage and therefore allow maximum effort to be applied to moving the piston along the bore of a cylinder. Consideration needs to be given to the pressures expected, the friction losses acceptable, whether a double acting capability is required, and whether the piston head is integral or split. |
| current export market | Taiwan, Europe, America, Asia, Africa, Middle East, etc |
| production equipment | includes vacuum vulcanizing machines, large-scale flat vacuum vulcanizing machines, rubber machines, CNC machine tools, temperature-controlled ovens and detectors. |
| material pu | pu material display higher mechanical strength, high abrasion ,wear and extrusion resistance, high pressure load capacity, as well as a high tear and elongation at break resistance .also have good flexibility and very good ageing and ozone resistance. |
| used for | widely used in mobile hydraulics as sealing solutions, injection molding machines, machine tools, in piston accumulator and also for standard equipment designing, especially a cylinder. ect |
