ST53 30kN Pneumatic Grip Wide Opening (pair)

This grip is single acting, with manual adjustment of the opposing jaw face. The closing force between the jaws is 28kN with a pressure of 7 Bar. The tensile force that can be applied to the sample will depend on its coefficient of friction with the jaw face. Samples up to 22mm thick can be accommodated between the jaws.

1mm pitch pyramid faces are fitted as standard, rubber and plain faces are available. The pyramid faces are hardened to 60HRC. All standard faces are 100mm wide × 45mm high.

A 3 position foot valve is supplied as standard, a hand control is available as an option. All pipe work, valves etc. are included. We do not supply the connection to the mains supply or mains filtering or regulation. It is recommended that non-lubricated filtered air is used. The 28kN clamping force is quoted at 7 bar, the maximum air pressure that can be used is 8 bar. The connection from the mains to the grip controller is by 4mm o/d semi-rigid nylon tube into a push fit connector. We supply 3 metres of this tube with each grip assembly.
