SKF roller screws for precision movement of heavy loads
SKF, the knowledge engineering company has launched its latest range of roller screws designed to offer smooth, accurate and reversible linear motion in applications ranging from demanding heavy-load steel and tyre industrial equipment, to high-precision CNC devices, laboratory machines and satellite technology.
The latest SR and SV roller screws are able to withstand far heavier loads than traditional ball screws, while maintaining high levels of precision and stability at all times. This is achieved by transferring the load from the nut to the screw shaft through threaded or grooved rollers, which provide stronger contact points than ball bearings, providing reliability and long low maintenance service life for machinery.
The range consists of the SR planetary roller screw and the SV re-circulating model. The SR is a robust steel device, featuring threaded non-recirculating rollers and a long lead symmetrical nut allowing a shock-resistant high-load carrying capacity of up to 12,000kN, and greater linear acceleration capabilities, in excess of 10,000 rads/sec/sec. Offering exceptional reliability and a long service life, the planetary roller screws are suitable for the most demanding applications, such as the machine tool, steel and tyre industry, as well as nuclear, military and automatic handling applications.
Likewise, the new re-circulating SV roller screw offers high positional accuracy and fine resolution capabilities, with precision and reliability achieved through its compact 1mm leads, which minimise drive torque and improve resolution. Again, providing long-life and exceptional reliability, the SV roller screws are ideal for advanced technology applications where optimum performance is vital, such as laboratory equipment, telescopes, and printing presses.
