Characteristics and performance
A robust assembly designed specifically for one piece pistons, the Hallite 53 double acting seal uses a rubber sealing element which has proved itself in service to be extremely wear resistant and capable of working most effectively in a wide variety of medium duty applications. The seal is also suitable for two piece pistons.
The assembly comprises a rubber seal, two split support rings and two split bearings, one of each located either side of the seal.
The nitrile rubber seal is designed to have its section compressed by the housing, to ensure a low pressure seal and , when pressurised, be protected from extrusion damage by the extending lips of the support ring. The support ring is manufactured from a tough flexible polymer and scarf cut for assembly.
Product range
The proportions of the range have been determined to give a satisfactory performance when used with the recommended operating conditions.
Note: Other sizes of this design are shown under Hallite 50, 64 and 68.
