Roller screws beat ball screw performance
A new range of satellite roller screws from Abssac are high-precision linear devices that transform rotary movement into a linear movement.
Using the standard RV series with a flanged mounting nut, meant that the physical roller screw's nut diameter could be significantly smaller than if a traditional style of ball nut had been used.
Additionally the roller screw enabled up to four times the axial thrust capacity for the equivalent ball screw design.
The satellite roller screw product has precision rollers instead of ball bearings in the nut housing.
The rollers transmit the load between the nut and the screw.
Since the rollers are constantly engaged with the threads of the screw, this results in a high number of contact points which allows the satellite roller screw to support heavier axial loads and have much greater longevity.
Interestingly, when the screw turns, the satellite rollers move as the lead on the screw and the rollers do not move axially relative to the nut, and they are not recycled. Request a free brochure from Abssac ...
