Roller Screws
In roller screws, the load is transmitted from the nut to the shaft through the barrelled surfaces of all the engaged rollers. The diameter of the contact surface is substantially increased as is the number of points of contact.

Features:
- High load ratings
- Very high rotational speed
- Long life at high cycling rates
- High reliability
- Resistance to hostile surroundings
- Small displacements with very good repeatability
