Roller Screws
For more demanding applications, Acorn offer a wide range of Roller Screw products in SKF manufacture - both planetary and recirculating roller type are available.
Roller Screws are used when high loads - up to 1,000 tonnes static and 200 tonnes dynamic, or high speeds and accelerations - over 1,200 rad/sec^2, are required.
Roller Screws also offer improved shock load performance and are able to operate in adverse environments. Please see the SKF roller screw catalogue for full details.
Features & Benefits of the Roller Screw
