Aston, PA – Amacoil-Uhing Model RG3 linear drives are now available with an option which doubles the drive's thrust capacity without significantly increasing the size of the unit. To double the drive unit's thrust, an extra rolling ring bearing is installed. The Model RG3 drive thereby becomes an RG4 drive. There are three rolling ring bearings in the RG3 model. The center bearing makes point contact with the drive shaft on two points generating the maximum side thrust the bearing can deliver. The two outside bearings, however, contact the shaft only on one point which produces half the thrust capacity for each bearing. The addition of the fourth bearing adds two more bearing-to-shaft contact points which doubles the thrust of the unit.
