The technology has many advantages over conventional devices, but is not for every application Rolling ring linear drives are used worldwide, to meet a variety of positioning and reciprocating linear motion applications.
These linear drives convert the rotary motion of a smooth, threadless shaft into linear output at fixed or variable pitch.Typically, in turn, reduces overall operating and maintenance costs, and permits uninterrupted production for longer periods of Time before the system needs to be stopped for adjustment.
A rolling ring linear drives operates on an unusual but simple procedure. It runs on a smooth case-hardened steel drive shaft. The threadless shaft passes through a series of rolling ring bearings situated in a load-bearing housing, or nut. Rolling ring bearings should not be confused with standard ball or roller bearings.
In a rolling ring bearing, each ring has a specially contoured inner race that bears against the smooth shaft. The rings are set at specific angles relative to the shaft
