PHD Series GRS Low Profile Parallel Gripper Review: Specs, Price and Applications
The PHD Series GRS is a low-profile parallel pneumatic gripper whose angled cam drive mechanism provides higher grip forces. It is double acting for internal and external gripping, with two jaw travels per size.
Optional spring assist increases force and retains parts on air loss. Precision-ground hardened jaws, hardcoated bearing surfaces and internal jaw seals give smooth, low-play operation, with mounting thread, dowel and port options.
Quick Verdict
A compact high-force gripper for limited-space applications, with sealed jaws for durability.
