PHD Grippers

Angular Grippers (Series GRB) *New Design

Series GRB Grippers provide up to 180° of angular jaw travel allowing the jaws to completely retract from the work area eliminating an otherwise required axis of travel. Internal shock pads help dampen end of rotation shock and ensure quiet operation.

Advantages: Robust cam design, adjustable opening, six sizes, field repairable

Benefits:

Interchangeable with previous design Provide up to 180° of total jaw rotation allowing the jaws to rotate completely clear of the work area eliminating an otherwise required axis of travel. Internal speed restriction eliminates the need for flow controls in standard applications. External flow controls are available as an accessory. Three total jaw rotations available: 60°, 90°, and 180°. Internal shock pads help reduce end of rotation shock on open and ensure quiet operation. Enclosed jaw mechanism helps prevent external contamination from damaging the unit. Close tolerance jaw width and dowel pin holes provide precise positioning for jaw tooling and fixturing The gripper body has two mounting surfaces with dowel pin holes to provide accurate mounting in a variety of attitudes. Optional 4 mm round inductive proximity switches, as well as Series 6790 Solid State and Reed switches are available on all sizes for indication of jaw position and simple interfacing with electronic system controls. Field repairable
Optional port location available

Design Improvements:

Increased grip force. Improved precision through decreased jaw side play. Larger piston rod and jaw drive provide a significantly more rugged gripper. One piece body provides superior interchangeability. Internal speed restriction removes the need for external speed controls in standard applications. Longer life seals. Increased diameter jaw pivot pins, on smaller sizes, provide increased robustness. Series 6790 Solid State and Reed switches now available on all sizes. Dowel pin holes added to jaws allow for simplified tooling and improved gripper to gripper interchangeability.
Proximity switches and kits are interchangeable between old design and the new design.
