DSPB
Dust Seal
Advantages and Characteristics
DSPB is composed of PTFE and an O-RING, where the O-RING on the static side has a sealing effect. Under pressure-less conditions, the O-RING can also provide a pre-tightening force for the PTFE seal. DSPB can scrape away dirt outside the cylinder and excess oil film on the piston rod. If the O-RING material is of good elasticity, it can also generate a liquid suction function.
With its low friction coefficient, PTFE can achieve fast linear and radial speeds, making it widely used in reciprocating and rotating hydraulic cylinders.
