Single seal is designed for uni-directional pressurization rods in hydraulic applications but it is also appropriate for double-acting pistons in hydraulic cylinders if two sealing sets are arranged. Typical applications include control cylinders, servo-controlled systems, machine tools, and construction machinery.
Application range
Pressure: ≤400BAR
Temperature:-60~+200℃
Speed: ≤4m/s
Material: Bronze filled PTFE
*Other materials are available for specified conditions

How to order
Note: For rod diameter≧1000.0mm, K should be added in prefix.
e.g. for seal 1200x1238x13.8mm should be denominated as RB-K1200-02T-1-H.
