Steinmeyer Inc. has added a 28 mm diameter screw with 12 mm pitch to its extensive line of precision ball screws. Normally, its product line is guided by the DIN standard that specifies shaft diameters of 20, 25, 32, 40 mm, etc. This new 28-mm diameter product was designed as a size compatible with the JIS standard. The ball screw is supplied with choice of two nut styles: single nut with flange series 1416, or double nut with flange series 1516. The ball nut is normally provided preloaded for zero backlash. The screw shaft is precision ground and offered in accuracy grades T0 to T5. Threaded length, journal details, and overall length are per customer specification.
