Zero-Max (Plymouth, MN) offers Roh’lix® linear actuators made from stainless steel for use where cleanliness is a priority. Used to convert rotary motion to linear travel, the actuators carry loads at speeds up to 70 inches per second, depending on size. Stainless steel components make the actuators suitable for food, drug, packaging, and similar applications where cleanliness and frequent system wash-downs are required.
The actuators turn rotational motion into linear motion much like a ball screw, with the added feature of overload protection. The actuators consist of three stainless steel ball bearings at each end of a two-piece stainless steel housing. Mounted at an angle to the drive axis, the six-bearing design converts drive shaft rotation into proportional linear travel.
