introduction：1、Structural characteristics：The inner and outer rings are made of high purity bearing steel with strict control of oxide impurities harmful to rolling fatigue life，Use contact Angle60º，The number of steel balls is equal to the structure design，The axial stiffness of the bearing is greater；Compared with tapered roller bearings and cylindrical roller bearings, the starting torque is smaller，Low driving force and high precision operation are realized；Used in pairs to withstand axial and radial loads or composite loads。 2、Contact Angle：60° 3、cage：Nylon cage guided by rolling element。 4、Velocity factor：Grease lubrication DmN≤400000 namely Limiting speedN≤400000/Dm Dm—Bearing middle diameter 5、Scope of application：It is mainly used in conditions requiring precision axial positioning and repeated positioning accuracy。Such as：CNC lathe lead screw support，CNC universal grinding machine lead screw support，Automatic CNC bearing ring grinding machine lead screw support，CNC machining center lead screw support and othe

introduction：method/procedure 1、Stepper motor can only be operated by digital signal control，When the pulse is supplied to the driver，In too short a time，The control system is sending out too many pulses，The pulse frequency is too high，The stepper motor will be blocked。To solve this problem，The method of acceleration and deceleration must be adopted。In other words，When the stepper motor starts，To give a gradually increasing pulse frequency，The pulse frequency needs to be gradually reduced during deceleration。Thats what we always talk about“Acceleration and deceleration”method。 2、So when the stepper motor starts at high speed，It is necessary to adopt the method of pulse frequency increase，There should also be a deceleration process when stopping，To ensure the precise positioning control of the stepper motor。Acceleration and deceleration work the same way。

introduction：Why does linear optical shaft adopt self-sealing technology To ensure tightness，The usual practice is to attach a sealing device to the supporting position of the linear optical shaft，This can effectively prevent foreign objects from invading，But this additional seal also takes up some space，Increase the axial size of the linear optical axis，Bring inconvenience to use, installation and maintenance。 Not only that，The practice of adding a sealing device at the support of the linear optical shaft has another shortcoming，That is, the sealing performance is also affected by the machining accuracy and line tolerance of the matching parts of the shaft diameter and the housing。so，The traditional sealing method of linear optical axis should be improved as soon as possible。
