Compact piston seal 55x39x18.4 (31.1) S=6.35 TPM

TPM/A105/TPL/KDSB TYPE COMPACT PISTON SEAL This compact seal is made of a central unit in NBR working as a seal, two side supports, working as anti extrusion ring, and two external guide rings, keeping aligned the piston in the cylinder. Technical data Pressure: from 0 to 300 Speed: < 0.5 m/s Temperature: from - 30 °C at +100 °C Fluids: Mineral oils Material The compounds used to manufacture this seal type are the following: • the central units is made of NBR, the hardness is 70 Shore A ± 3 • the sides support are made of a thermoplastic elastomer (PU) • the external wear rings are made of polyacetal resin (POM). Assembling The assembling of this seal can be carried out in either closed groove in a mono-block piston, or in open groove in a two-parts piston. The assembling has to be done as follows: • rubber element • supports • wear rings. Avoid machining scores on the piston which may damage the rubber unit during the installation.
