DESIGN
The Hailite type 754 double acting piston seal Is a compact low friction seal for light to medium duty hydraulic cylinders. It comprises a tough, wear resistant thermoplastic elastomer face which is pre-loaded by an *C ring. The housing width allows a narrow width piston to be used, but It is recommended that an adequate bearing Is mounted on one or both sides of the seal. Housing dimensions for use with Hailite type 67 and type 506 bearing strip are given in the installation details. For further details of bearing strip grooves, please refer to the appropriate data sheets. NB: Part numbers suffixed by"+" Indicate housing sizes to meet ISO 7425-1.
INSTALLATION
Unlike PTFE seals It Is not generally necessary to use a cone to assemble the type 754 onto the piston, the elastomeric material will stretch sufficiently without problems.
