How to choose Rod Seals

Points to check when selecting, with the values for this product (S02-PD).

1. 1. Match rod diameter and groove dimensions

   A seal is specified by the combination of applicable rod diameter and installation groove dimensions. The applicable rod diameter of listed products is 5 to 1000 mm. When fitting into an existing groove, check on the drawing that, in addition to the rod diameter, the groove width and groove bottom diameter match the standard combination.

2. 2. Verify cross-section and groove width

   Cross-section dimension (c/s, radial thickness) corresponds to the groove depth, and groove width L corresponds to the axial length. The listed range is 2.45 to 20 mm cross-section and 2.2 to 50 mm groove width. If dimensions do not match, insufficient squeeze causes leakage, and excessive compression causes early wear.

3. 3. Maximum operating pressure and backup rings

   This product: Maximum Operating Pressure 700 bar

   The maximum operating pressure of listed products is 160 to 700 bar. At high pressure, the seal tends to extrude into the clearance and fail, so consider types with square or trapezoidal backup rings. Confirm that the pressure, including pressure surges (momentary pressure rises), stays within the upper limit.

4. 4. Select material by temperature and fluid compatibility

   PU offers excellent wear resistance, while PTFE has high chemical and heat resistance and low friction. Rubber-based materials vary in oil and heat resistance depending on their compound. Operating temperature ranges differ by material, so select a material that suits the working fluid, such as hydraulic oil, water, or air, and the operating temperature.

5. 5. Check the upper limit of sliding speed

   This product: Maximum Sliding Speed 0.5 m/s

   The maximum sliding speed of listed products is 0.5 to 10 m/s, which varies greatly by material and type. Use at high speed accelerates deterioration due to frictional heat. Check that the maximum cylinder speed is within the upper limit, and consider low-friction PTFE-based types for high-speed applications.

6. 6. Select seal type and operating method

   Rod seals are basically single-acting types that receive pressure from one side. In high-pressure systems, there is a method of combining them with buffer seals. For large machines that are hard to install or have worn rods, chevron packings, which can be selected as split types, are suitable.
