Actuators convert rotary motion into linear motion
DPN WEB EXCLUSIVE: Roh'lix linear actuators from Zero-Max convert rotary motion to linear travel and carry loads at speeds up to 70 ips, depending on size. Designed to handle thrust rated between 5 and 200 lb, loads can be attached to the carrier block using two cap screws.
The thrust capacity is adjustable so that the system will disengage if the preset thrust is exceeded, providing overload protection if an obstruction is encountered in the system. The linear actuators consist of three precision ball bearings (which are replaceable) at each end of a two-piece aluminum carrier block. Mounted at an angle to the drive axis, the six bearings convert drive shaft rotation into proportional linear travel.
With a minimum of 90% efficiency, the actuators can normally provide up to 100 million in. of linear travel. The moveable carrier block travels on a threadless hardened RC 58 shaft that requires no lubrication. Five sizes are available for 3/8 to 2 in. diameter shafts, or metric sizes from 8 to 50 mm diameter shafts.
