Grippers

Information applies to models P-6950, P-7000, P-7100, P-7150 and P-7200, also known as Long-Stroke Grippers. This product cannot be sold outside of the United States.

ASSUMPTIONS Used to Determine Maximum Payload:

System Pressure = 100 psi (6.9 bar) | Maximum = 120 psi (8.3 bar)
Maximum Acceleration/Deceleration = 1G – 386 in/s² (9.8 m/s²)
Part Friction (µ) = 0.25 (Does Not Apply to Encompassing Grip)
Finger Length = 0.00 in (0.00 mm) | “PX” Models = 5.00 in (127.0 mm)

This comparison chart depicts a Grip Force (from each jaw) to Mass ratio of the Long Stroke parallel gripper Series to those of the competition (based on catalog information). Various aluminum alloys were employed with custom tempering and heat treatments to reduce mass. In all cases the new materials exceeded the durability of the classic materials in industry tests. In addition the design was refined to reduce the number of steel fasteners utilized by reducing parts count with current CNC tooling.
