Grippers - 3-Jaw Overview
RAD offers a line of durable 3-jaw pneumatic parallel grippers designed for applications requiring three points of contact. RAD's 3-Jaw Square Jaw Brute™ Parallel Grippers are pneumatically operated, offering high grip force to moment ratio and synchronous jaw motion.
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 (00.0 mm), "PX" Models = 5.00 in (127.0 mm)
