Grippers

Information applies to gripper models P-3100, P-3200, P-3300, and P-3400, also known as Square Jaw Brute Grippers.

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)

Model	Height Dimension “A”	Length Dimension “B”	Jaw Dimension “C”	Width Dimension “D”	Weight	Cylinder Bore Diameter	Centering
P-3100	80.0 mm	81.0 mm	25.4 mm	45.0 mm	0.5 kg	32.0 mm	+ 0.03 mm
P-3200	102.0 mm	109.0 mm	34.9 mm	64.0 mm	1.1 kg	50.0 mm	+ 0.03 mm
P-3300	147.0 mm	161.0 mm	50.8 mm	98.0 mm	3.0 kg	80.0 mm	+ 0.03 mm
P-3400	182.0 mm	219.0 mm	69.9 mm	115.0 mm	7.0 kg	100.0 mm	+ 0.03 mm
