Ball Screw Precision Grades
Precision ball screw rolled ball screw accuracy grades c0 c1 c2 c3 c5 c7 c8 c10 type series symbol grade remarks for positioning c 0 1 3 5 jis series cp 1 3 5 iso compliant for transport ct 1 3 5 7 10.
Ball screw precision grades. Accuracy grades c0 to c5 are de þ ned in the linearity and the directional property and c7 to c10 in. Go to the resources tab and how a ball screw works for more information on internal or external return systems. Precision ball screw lead accuracy conforms to four characteristics spelled out in the jis standards. By screw shaft they are divided into precision ball screws which are ground with precision six accuracy grades from c7 to c0 and rolled ball screws which are formed through rolling with high accuracy three accuracy grades from c10 to c7.
Ep v u v 300 and v 2π. The accuracy of the ball screw in the lead angle is controlled in accordance with the jis standards jis b 1192 1997. Precision ball screws thread diameter 12 lead 2 4 5 or 10 precision grade c3 c5 or c7 misumi of misumi check out the variety of configurable precision ball screws thread diameter 12 lead 2 4 5 or 10 precision grade c3 c5 or c7 misumi of misumi misumi has other mechanical components press die and plastic mold products available. The accuracy of the ball screw is controlled in accordance with the jis standards jis b1192 1997.
Is the industry leader for best delivery of new precision ground semi precision and commercial grade ball screws with internal or external ball return systems. So for instance an accuracy grade c0 precision ball screw is more accurate than a c2 a c3 is more accurate than a c5 and so forth. Nsk ball screws were developed through cutting edge tribology friction control technology and nsk manufactures the largest volume in the world with its outstanding production and quality control techniques. Also a series of nut rotating ball screws which are optimal for usage based on nut rotation.
The ball screw grading scale ranges from zero to ten with each level corresponding to a different degree of accuracy. Ball recirculation hole return tube screw shaft ball nut screw shaft end deflector ball screw b 1 2 1 ball recirculation system a ball recirculation system is categorically most important as well as the preload system to classify the structure of ball screw. Miniature ball screws are a very efficient 90 98 way to translate rotary motion into linear motion versus lead screws that are typically less than 50 efficient. Ideal application are in medical devices laboratory automation and semiconduction equipment.
These high efficiency miniature metric precision ball screws are a very cost effective solution for use in small or compact spaces. With the world s leading ball screw nsk has been contributing to industrial growth.
