PHD Series GRL Narrow Parallel Gripper Review: Specs, Price and Applications
The PHD Series GRL is a narrow-width, low-profile parallel pneumatic gripper with long jaw travel, in imperial and metric sizes. Grip force reaches 41 lb (182 N) at 87 psi (6 bar).
Jaws stay parallel to the part across sizes and come in synchronous or non-synchronous versions. Optional manifold ports eliminate external air lines, dowel holes in jaws and body align tooling, and the unit is rated for at least 6 million cycles.
Quick Verdict
A slim, long-stroke gripper that fits narrow spaces and handles varied part widths with manifold porting for tidy tooling.

Design and Operating Principle
A narrow body slips between fixtures or into tight spaces, while long travel covers a wide part range without finger changes.
Non-synchronous jaws adapt to parts that are not exactly centred.
Manifold porting routes air through the mounting face, removing hoses that could snag.
Integration and Selection
Size the unit from the required force at the actual tooling length, including acceleration and a safety factor, and check allowable moments. Use PHD's sizing data, since force and travel values vary by size.
Choose synchronous for centring or non-synchronous for compliance, and use manifold porting where possible.
