UHING RG3R-30-2MCRF Rolling Ring Drive

Technical Specifications & Drive Principle

The UHING RG3R-30-2MCRF rolling ring drive is a precision engineered unit designed for a 30 mm shaft diameter. Built on the rolling ring principle, the unit converts continuous rotary motion of a smooth shaft into a controlled reciprocating linear movement. The mechanism employs multiple rolling rings pivoting on anti-friction bearings, pressed against the shaft by an inclined profile to generate thrust. Maximum side thrust is approximately 260 N for the 30 mm version, and maximum traverse speed is around 0.40 m/s. Key features include adjustable pitch (including zero pitch for standstill), selectable direction reversal, and a compact design optimized for industrial use. This drive represents a ready-to-install industrial drive unit for demanding linear motion tasks.

Industrial Applications & Integration

This rolling ring drive is tailored for industrial applications such as winding machines, material handling systems, packaging lines, spooling equipment, and linear feed mechanisms. Because it transforms shaft rotation into linear travel without need for screw drives, it simplifies integration into high-performance installations. The RG3R-30-2MCRF unit is ideal in setups where repeated reciprocating motion is required, and where reliability, compactness and ease of integration matter most. As a complete unit it fits directly into machine assemblies, supporting drive systems and automations with minimal additional design effort.

Benefits for B2B and Maintenance Teams

• High durability: Robust construction and optimized rolling ring mechanism deliver long life even under continuous operation.

• Plug-and-play unit: The drive arrives as a complete module, reducing assembly time and risk of mis-integration.

• Precise pitch and direction control: Operators can adjust stroke length and direction without mechanical rebuilds.

• Flexibility in industrial environments: Designed for integration into varied systems requiring robust linear motion, reducing downtime and maintenance efforts.

• Supply readiness for B2B clients: Ideal for production lines, maintenance programs and industrial upgrades where time-to-install is critical.
