Uhing Company has introduced the RS4 linear drives. Available in seven sizes, the drives feature shaft rotational speeds of up to 10,000 rpm, travel speeds from 0.5 ft/sec to 4.0 ft/sec, and axial thrust of 22-449 lbs. Specially machined Uhing rolling ring bearings are installed under pressure inside the drives, creating a constant single-point contact between the bearings and the drive shaft and resulting in zero-play without the need for other anti-backlash solution.
