Misumi offers its precision linear shaft that features a consistent hardening depth and a light pre-load to minimize clearance design between the shaft and bushing; this allows for smoother, more precise and quieter operation, the company says. Most of the company's linear shafts come in many varieties with most offering configurability in 1-mm increments and a range of end designs. The shafts can come in 52100 bearing steel and 440C stainless steel as well as outside diameter sizes from 3 to 50 mm and lengths from 10 to 1,500 mm. Length tolerance, wrench flats, set screw flats, key groove, V-groove, relief and other end designs are available.
