IPR WG and RA Angular Grippers Review: Specs, Price and Applications
IPR's angular grippers are designed for handling spherical and round workpieces. The WG series opens up to 180° and delivers clamping forces up to 380 N at 6 bar (87 psi), with jaws running on needle bearings for smooth, precise motion.
The RA series has a 30° opening angle, a low-profile design and direct force transmission to the jaws for high efficiency, making it suited to small parts.
Quick Verdict
Two complementary angular families: the WG for wide-opening, high-power gripping and the RA for compact small-part handling.

Design and Operating Principle
Angular grippers suit round parts because the jaws can be shaped to cradle a sphere or cylinder. The WG's 180° opening folds the fingers fully away, allowing approach from the side or retreat without lifting.
Needle bearings in the WG jaws reduce friction and play, giving precise and repeatable closing. The RA's direct force path delivers efficient force in a flat housing for small-part assembly.
Both families use pneumatic actuation for fast cycles.
Integration and Selection
Choose WG for wide opening and higher force, RA for compact small-part handling. Design jaw contours for the part shape and check force at the finger length.
Allow space for the WG's full 180° swing.

Who Should Consider the IPR WG and RA Angular Grippers?
These grippers suit handling of spherical and round parts and small-part assembly.
Price and Availability
Price: Request a quote. IPR prices the WG / RA by size, options and quantity, so the final figure depends on the exact configuration. Budget for the complete tooling package, including fingers or adapters, mounting, air or electrical connections and commissioning time, rather than the module alone.
