DF054
Design Introduction
Kintowe DF054 double acting piston seal provides the designer with a compact, low friction seal for light to medium duty hydraulic cylinders. It comprises a PTFE face 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 O-ring deforms and compresses the PTFE face ring against the tube wall increasing the sealing force and the effectiveness of the seal. As only the PTFE face 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. Different kinds of material options for PTFE face ring can be provide to extend operating conditions . Kintowe DF054 seal is not recommended for applications where it is necessary for the pressurized cylinder to maintain the load in a set position.
Advantages
● High maximum speed
● Compact piston design
● Low breakout & running friction
● Low stick/slip
● Any size can be machined
