High load capacities

SKF Ultra Power range of Planetary Roller Screws has been optimised to provide the maximum possible life within a compact space envelope. This has resulted in an increase in capacity of up to 60 % over the standard product. Load capacity is independent of lead. To attain L10 life performance a mean working load of up to 80 % of Ca is allowed (50 % for HRP/HRC 60). The maximum load should not be applied on the mounting bolts but on the flange.

Applications

The “Ultra Power Range” offers the power of hydraulic actuators combined with the precision and flexibility of electric control, for example:

• injection molding machines for plastic and rubber
• presses
• broaching machines
• the steel industry including casting & rolling
• friction welding
• hydro-electric plants
• actuators.
