The coupling is an essential part of the stepper motor，Also the main accessories，Its main role in the stepper motor is to drive，Act as a hub，Specifically, it is used to connect the stepper motor shaft and the driven shaft，To transmit torque，This requires that the coupling must have precise rotation performance，If the rotation performance is relatively slow, it will greatly reduce the efficiency of the stepper motor。meanwhile
Rigid coupling parts： 1、Sleeve coupling。It is made of sleeve、chain、Set screw or pin composition。 2、Flange coupling。It is a kind of fixed coupling widely used，It is composed of two half couplings and connecting bolts separately mounted on the shaft end。 3、NZFlexible claw type coupling。This is a rigid hand moving coupling，Consists of two half-block couplings with wider grooves and one
How to measure the radial clearance of deep groove ball bearings，When choosing one with a cone holeIKOWhen bearing, it is required to match the interference amount than the cylindrical hole。Because when you have a larger amount of interference，This will cause a decrease in radial clearance，Therefore, the reduction of radial clearance should be taken into account when selecting。
There are many kinds of guides，The range of use of different guides is also different，Want to know what type of rail is right for you？See below for details。
Whether the outer packing is clear Double row tapered roller bearings in general，Brands produced by regular manufacturers have their own specialized designers for external packaging design，And arrange the production of factories with satisfactory production conditions，therefore，Product packaging None
HIWINBall screw、Ball screw，Whether the outer packaging of imported bearings is clear under normal circumstances，The imported bearings of the factory brand have their own special designers for external packaging design，And arrange factories with satisfactory production conditions
Rexroth linear guide1、Before assembly，The inside of the guide rail must be cleaned and greased。2、IKOWhen the guide is pressed into the support seat，Special devices should be used to press against the outer ring face，Do not directly tap the rail，Avoid deformation。3、railI
