Roller Screws for Linear Actuation
by Kathryn Tomiello
Monday, May 14, 2007
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.
