Detailed Product Description

Hollow Shaft or threaded shaft stepper motor for Linear Actuator

Nema11, Nema14, Nema17, Nema23 and Nema34

Bespoke ball screw

•Hollow Shaft or threaded shaft step motor
•Nema8, Nema11, Nema14, Nema17, Nema23 and Nema34
•Bespoke or ground leadscrew •POM nut, brass or anti-backlash nuts
•Normal treatment Trapezoidal, Acme standard Leadscrew or Teflon Coating for longer life time and smooth linear motion
•Customized length and resolution, leadscrew diameters.

These kind of linear stepper motor or step motor linear actuator have a hollow shaft or threaded shaft, which allows them to be used as a linear actuator with Bespoke Leadscrew or Ground Leadscrew. Brass nut, POM nut or Anti-backlash Nuts. Stainless Steel Acme standard Trapezoidal Leadscrew with normal treatment or Telfon Coating treatment for anti-corrosion or special long run and smooth applications. As the motor runs, it moves along the leadscrew or ballscrew at a specific rate of 1cm per 5 or so full rotations. These are a good choice for linear motion where precision and repeatability are important.

Q: I'd like to make my own lathe screw. What material should I use?: The ordinary lathe screw is only the general precision grade, and the requirement of the abrasion resistance and the material deformation is not particularly high. So use 45# or 40Cr conditioning.If it is a precision machine tool, such as a rib grinder or an ultra long connecting screw, it requires a high resistance to wear, a small amount of deformation, and can maintain the accuracy for a long time. Use 9Mn2V or CrWMn quenching.

Q: How can the accuracy of the CNC machine tools be compensated after a few years?: The gap clearance of the screw bar is adjusted on the parameter. The old version of FANUC is 535 refers to the X axis, and the 536 refers to the Z axis, and the new version is 1851, and the inside is divided into the X/Z axis

Q: I would like to ask what method installed, do not know how many balls, loaded and loaded less, what is the situation, ah, urgent, thank you: [method for installation of ball screws]The ball screw nut pair is only used to bear axial load, the radial force and bending moment will cause the ball screw nut pair additional surface contact stress and other loads, which may lead to permanent damage to the lead screw. Proper installation is the prerequisite for effective maintenance. Therefore, the ball screwWhen the nut is attached to the machine, attention should be paid to the following points:The axis of the screw must be parallel to the axis of the supporting rail. The bearing block and the nut seat at both ends of the machine must be in line at three.Install the nut as close as possible to the support bearing.Install the supporting bearing as close as possible to the nut installation site.When the ball screw is installed on the machine, please do not remove the nut from the lead screw.If you have to remove the use of auxiliary sleeve, or loading and unloading of the ball may fall off. The following points should be noted when handling nuts:The outer diameter of the auxiliary sleeve should be less than the bottom diameter of the screw 0.1-0.2mm.Auxiliary cover in use, must rely on tight screw, screw shaft shoulder.The uninstall, can not be too large, so as not to damage the nut.When loading the installation hole, avoid impact and eccentricity.

Q: Is the grease of the machine tool screw rod good or weak?: Screw rod bearings relatively high speed, should be diluted (low viscosity) of grease, with high viscosity grease will lead to increased friction, temperature rise, the result is easy to burn bearings.

Q: What material is used for the screw nut of machine tools?: As the screw rod 1 to compressive strength and fatigue resistance enough 2 has certain plasticity and toughness, low coefficient of friction and good running in 3 has good thermal conductivity, thermal expansion coefficient and corrosion resistance of low alloy, sliding bearing

Q: How about the central screw in the CNC lathe? Or an ordinary side screw!: Sen's advantage: cheap. Disadvantages: in addition to cheap. 6136 a little more than 5. Buy 36, buy 40, not much money. I don't know how high the power of the 36 spindle is, anyway, 40 is 5.5KW. Variable frequency spindle is more sensitive to power. Low speed, the output force is not enough, and sometimes will stop the spindle. Now that you choose big Sen, you value his merits. Well, I won't comment either. The design of the middle screw leads to the inconvenience of cutting, and no improvement has been found in the design process. Goods than three in order to find quality products, the boss, you may as well more Internet, check different machine tool factory products, learn more to earn more. I wanted to go on, but when I saw the eggs, I was really embarrassed to go on.

Q: CNC machine tool screw gap: For a pure driving situation, general requirements for flexible transmission, allow a certain return to the gap (small, usually a few silk), using a single nut, it is cheaper and more flexible transmission; for a return to the precision of gear clearance conditions is not allowed, it is required to choose double nuts, it can adjust the magnitude of pre tightening force, keep good, and can be repeatedly adjusted; in addition, restricted travel in space, also can choose the variable lead preload (commonly known as stagger preload), the pretightening force is small, and it is difficult to repeat adjustment, generally do not choose.If the gap is large, please timely maintenance, system compensation value can not be too large, in the case of large gap screw, continue to use, will greatly shorten the service life of the lead screw, and easy to cause damage can not be repaired

Q: The Z shaft screw is close to the motor and is equipped with 3 angular contact bearings. There are 2 bearings under it. Ask experts to teach me how to install, the top 3 how to arrange, the following 2 how to arrange, thank you!: The following two big faces, the two should be connected in series; the three above two and the two below are Shun Zi; that is to say, the four of them are connected in series; the top one is face-to-face
