Characteristics and performance
The Hallite 50 comprises of a rubber seal, two split support rings and two split bearings, located either side of the seal. The nitrile rubber seal has proved itself to be extremely wear resistant in service.
It is designed to be 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. A tough flexible polymer is used for the support ring which is scarf cut for assembly and to protect the seal from damage.
A rectangular reinforced nylon bearing completes the assembly and provides the seal and piston with support and guidance.
The proportions of this range of piston seals have been determined to give a satisfactory performance when used with recommended operating conditions.Ask an expert
