Claron Polyseal Single Acting Rod Seal HBT

Design:

Claron style HBT is a single acting seal for gland applications. Designed as a high pressure, low friction seal for use in second generation tandem sealing arrangements where the lower friction seal is used on the pressure side, and a ‘low leak’ but higher friction seal on the non pressure side to collect the oil film during the positive stroke. This type of arrangement is used where both low friction and low leakage are required. The seals high pressure resistance makes it suitable for use in heavy duty applications where shock loads and pressure spikes occur, as found in mobile plant equipment.

Materials:

Both the inner sealing element and the energiser are available in a wide range of materials to suit a variety of applications. The inner sealing element is manufactured from high performance Bronze filled PTFE, energised by an NBR O-Ring as standard.

Operating range:

Maximum Working Pressure Bar (For Standard Materials)

Optimum service conditions are affected by temperature, speed, pressure, surface finish and extrusion gaps.

Refer to Appendix 1 for further information.

Note: Clearance gap F is the maximum permissable. i.e. gap completely on one side, in the temperature range

of -30°C to 80°C

The use of a suitably selected Claron bearing ring will effectively reduce the clearance gap F max. to a value closer to F/2 thus increasing the pressure capability of the seal.

F/2 should be calculated allowing for all movements due to side-load and cylinder expansion.

 

Housing:

For surface finish and recommended lead in chamfers refer to the illustration below. For housing dimensions and machining tolerances refer to the catalogue page of selected seal. For value of E/2, refer to the bearing ring requirements.

Refer to Appendix 4 for value of tolerance symbols.

Fitting:

Style HBT may be deformed and fitted into a closed groove. For the seal to function correctly, it is important that care be taken in fitting the seal within its housing. For a detailed checklist, refer to Appendix 3.
