DESIGN
Hallite's 54 double acting piston seal comprises a PTFE ring, strengthened with additives to resist creep, which is pre-loaded by an 'O' ring to be effective for the operating pressure range recommended. As the pressure rises the xO' ring deforms and compresses the PTFE ring against the tube wall increasing the sealing force and the effectiveness of the seal. As only the PTFE ring is in contact with the sliding surface, friction is very low and stick-slip movement is eliminated.
The housing width allows the designer to use a narrow width piston, but it is recommended an adequate bearing is mounted either side of the seal as shown."
Standard sizes are supplied with a nitrile vO'ring but other materials can be provided.
The Hallite 54 seal is not recommended for applications where it is necessary for the pressurised cylinder to maintain the load in a set position. For this requirement see Hallite 754 and 755.
A number of material options can be provided for this product. Please ensure that the correct part number is specified for the material option that is required. See left for details.
