Grippers - 2-Jaw Overview
RAD offers a diverse line of 2-Jaw pneumatic parallel grippers to enable you to effectively grip, manipulate and place objects in your manufacturing process.
This information is provided as a starting point to help narrow the selection of RAD grippers that could potentially meet your needs. Any change from the stated assumptions will affect the selection of the proper gripper for your application.
ASSUMPTIONS Used to Determine Maximum Payload:
-
System Pressure = 100 psi (6.9 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)
