iglide® PRT-04 Slewing Ring with M4 Universal Locking Mechanism Adapter

The custom-actuator-ready locking configuration in the PRT-04 product line. The locking bolt body is fitted with an M4 threaded interface, letting users attach their own actuator, linkage, lever, or release mechanism without modifying the bearing itself. Maximum holding force of 350 N matches the standard -ART variant, and the rest of the configuration remains unchanged: 90° indexed positions, compact lightweight build, full PRT-04 modular compatibility. The right call when none of the prebuilt release options (manual hand-release, Bowden cable, electronic monitoring) fits the design intent.

When to use it: Indexed mid-duty rotary applications where the actuator needs to be customer-specific.

When not to use it: When standard hand release works (use the base -ART for lower cost), when remote cable release fits the brief (use the -ART-RC), or when electronic state monitoring is the priority (use the -ART-PD).

Application areas: Custom automation builds, integrated linkage systems, OEM products with proprietary release mechanisms, instrumented test fixtures, and any indexed rotary application where the actuator interface is part of the customer’s design.
