Rodless actuator R2A series

linearelectricball screw

The R2A Series offers a carriage bearing design that produces lower bearing friction, smoother operation and zero running clearance. A flexible seal prevents environmental contamination and ensures long life to provide an effective, industrial-grade solution. Belt-drive models offer the most rapid moves, while screw-drive designs offer the highest thrust capacity and repeatability. Motors available for use with the R2A Series include: • Kollmorgen T22T and T31T Series hybrid stepper motors (P7000 drive recommended) • Kollmorgen R2A-AKM23C, and 23D Series AKM™ brushless servo motors • NEMA 23, 34 and custom motor mounts Features • Lead screw, ball screw or timing belt drives • Max length: 1,829 mm (72 in) • Max thrust: 450 N (100 lbf), screw models • Max speed: 2,000 mm/s (80 in/s), belt models • Stepper, brushless servo and custom motor options • Internal guide bearings:4 angular contact bearings with a ground Gothic arch raceway running on dual precision rails • Bearing housing: Type 380 die-cast aluminum, epoxy coated • Carriage assembly: 6063-T6 aluminum, hard-anodized • Guide housing: 6063-T6 aluminum, hard-anodized, Teflon-impregnated • Acme screw: 0.625" diameter alloy steel screw, bronze nut • Ball screw: 0.625" diameter hardened alloy steel screw; alloy steel, heat-treated ball nut • Belt drive: 0.5" wide polyurethane with steel reinforcement cords • Helical gearing: alloy steel, case-hardened Options • Standard or custom lengths to 0.1 inches • English or metric carriage mount • Motor or screw brakes • Magnetic home and limit sensors • Single or dual carriages • Belt or helical gear, parallel or inline direct transmission • Water resistance protection
