Roller screws for linear actuation can sustain static loads to 1,000 tons and dynamic loads to 200 tons, depending on type. The screws incorporate fine-lead threads, as small as 1 mm.
Their robust nut can withstand shock loads; their timing mechanism is reliable at high acceleration; and a long lead and symmetrical nut design permits high linear speeds.
Applications include assembly (welding, riveting, and pressing) ; handling (clamping, gripping, and robotics) ; and injection molding (injection, blow molding, and thermoforming). The roller screws are ideal for factory automation and designed for use in harsh industrial environments.
