PHD Series GRB Angular Gripper with 180° Jaw Rotation Review: Specs, Price and Applications
The PHD Series GRB is an angular pneumatic gripper with jaw rotation options of 60°, 90° or 180°, in six sizes. At 180° the jaws rotate fully clear of the work area, eliminating an axis of travel.
Internal shock pads dampen end-of-rotation shock for quiet operation, an internal speed restriction removes the need for external speed controls, the enclosed jaw mechanism resists contamination, and a one-piece body improves interchangeability.
Quick Verdict
The 180° option is the standout: jaws fold out of the way so the robot can skip a retract move.

Design and Operating Principle
With normal grippers, the robot must lift clear after releasing a part. A 180° GRB opens its jaws fully out of the way, so the gripper can move sideways immediately, saving an axis or cycle time.
Shock pads and internal speed control protect the mechanism and make operation quiet.
An enclosed mechanism keeps chips and dirt out.
Integration and Selection
Choose rotation angle based on clearance needs and size based on force. Allow space for the full jaw swing.
Size the gripper from the required grip force at the actual finger length, including acceleration and a safety factor, and check the allowable moments for the jaw tooling. Use PHD's sizing data, since force and travel values vary by size.
