SKF roller screw jack actuators serve as practical alternatives to hydraulic or pneumatic systems for positioning applications in the steel and metalworking industries. These self-contained linear actuators require less power to raise and lower heavy loads quickly without overheating.Among typical applications, these low-maintenance actuators can be used to position the tundish in continuous caster operations. They can reliably move loads and apply suitable forces, enable faster operation, and provide longer travel under high load.
Their rugged design can withstand shock loads and promotes longer service life even under adverse conditions characterized by abrasive contaminants, poor lubrication, or high temperatures.
These actuators incorporate a roller screw and nut ring gear assembly supported by two bearings and driven by a worm gear in a stationary housing. The configuration distributes compression loads evenly for optimized handling of heavy loads in one direction. Multiple contact points in the roller screw design maximize load-carrying capacity.
Roller screw jack actuators are available in a wide range of roller screw diameters and can be supplied with equipment options or otherwise customized to satisfy particular application requirements.
