Precautions of Ball Screw
■ Precautions for Selection and Use
● The noise value of the Ball Screw after assembly is not guaranteed.
● Although lithium soap-based grease has been applied at the factory, it is required to apply new grease every 2~3 months as standard after receiving the goods, otherwise the normal use will be affected.
●In operation, if there is too much noise or sharp and harsh sound, please make sure that the installation accuracy of the Ball Screw and the specifications of peripheral components such as motors and couplings are appropriate.
●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 touse.

■ 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 Screwto 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 (Diagram 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 (Diagram 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

Brand Introduction
Since its establishment in 1963 in Japan, MISUMI Group Inc. has been providing customers with a wide range of high quality parts such as FA factory automation parts, mold parts, electronic parts, tools and consumables in a fast and accurate manner. We have created a low-cost business model by compiling our own catalogs and establishing a marketing system to sell our products directly, and we continue to develop MISUMI branded products with a high level of quality by developing an annual product plan based on customer feedback and requests. MISUMI established MISUMI Precision Machinery Co., Ltd. in China in June 2003, and then changed its name to MISUMI (China) Precision Machinery Trading Co., Ltd. in June 2007, with its headquarters in Shanghai. Since the beginning of the stamping die standard parts business, the businesses of FA standard parts, plastic die standard parts and machining tools have been officially started successively, and the rapid development of MISUMI in China has won the full support of customers. China's manufacturing industry has unlimited prospects, which is why China's manufacturing industry market has become one of the most competitive industries in the world. Thus was born MISUMI's business philosophy - the key to the future of manufacturing in China is cost competitiveness as well as "quality" and "time".

Frequently asked question (FAQ)
- Question: What is the operating temperature limit for the ball screw?
- Answer: The operating temperature limit for the 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. Grease has a good effect of reducing the temperature, so regular maintenance such as grease injection to the ball screw will improve the service life of the screw.
- Question: How to do if there is abnormal noise heard in use?
- Answer: 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.
