What is the operating temperature limit for the economy series rolled ball screw?

The operating temperature limit for the economy series rolled ball screw is 80°. Exceeding this limit will cause damage to the circulating parts and seals, as well as the deformation of the screw shaft and nut, affecting the life.

How to do if there is abnormal noise heard in use?

MISUMI does not guarantee there is no abnormal noise during use. If abnormal noise occurs, please check the installation accuracy and the correct selection of surrounding parts. Please loosen the parts before re-adjustment. Please refer to 'Precautions' for details.

Is it normal to feel stuck when rotating the nut by hand?

It is a normal phenomenon, because this product is a rolled ball screw, and there is no run-and-fit test before leaving the factory. The sticking will disappear after running for a period of time under the condition of ensuring the installation accuracy If the sticking reaches the point where the motor can not drive, please contact MISUMI.

Example of Use 1

Precautions

■ Selection and Precautions for Use of Ball Screw
● Rotating the nut by hand may not feel smooth, but does not affect the positioning precision, so this product is suitable for multi-point positioning feeding mechanism. Please feel free to use.
● If the operation requires low runout (e.g. machining equipment), please use MISUMI standard products.
In operation, if there is too much noise or sharp and harsh sound, please make sure that the installation accuracy of the screw and the specifications of peripheral components such as motors and couplings are appropriate.
● Lithium soap grease. SHC32 (red) has been applied.
Do not let the nut exceed the movement range of the ball screw nut, or screw out of the screw shaft, otherwise the ball will fall off and the ball cycling parts will be damaged.
● Ball Screw and nuts placed with an inclination may fall due to weight. Please be careful.
● This product is a machined type, so there will be knife patterns and color difference in its appearance. Small scratches or color changes without affecting the use and main function are of a normal phenomenon. Please feel free to use.

■ Precautions of the Ball Screw and peripheral parts design and assembly
The ball screw is a component that only bears axial load. If it is subjected to radial load or moment load, poor sliding, vibration or abnormal noise may occur, shortening its service life.
The reason that the ball screw bears radial load and moment load is the axis deviation and parallelism error of the surrounding parts. Therefore, it is necessary to correctly design and assemble the peripheral parts of the ball screw to prevent errors.
● Axis deviation of Ball Screw and support unit (Fig. 1)
- Axis deviation is the deviation of the ball screw fixed by the fixed side support unit and the bearing of the supporting side support unit.
- The allowable value of the axis deviation is 20μ or less (reference value)
●Parallelism between Ball Screw and linear guide (Figure 2)
- Parallelism error refers to the inclination of the ball screw in the up-down or left-right direction with respect to the reference of the linear guide.
- The allowable value of inclination is below 1/2000 (Figure 3)
●Precautions of assembly
If you notice abnormal noises during the operation of the ball screw or jamming during movement after assembly, please loosen the connections of the parts before proceeding. Adjust and reassemble after moving smoothly.
- Error in the left and right direction of the support unit (Fig. 1)
- Parallel error of linear guide and ball screw (Fig. 2)
- Fixing of workbench and nut bracket
- Fixing of ball screw nut and nut bracket

·Removal of nut is prohibited	·No impact on the nut	·Be careful of falling due to weight


·Checking for reverse action	·Pay attention to intrusion of foreign objects	·Nut overstroke is prohibited
