Ball screw is a common mechanical transmission element, widely used in CNC machine tools, automation equipment and precision machinery. So what does the SFU1605 ball screw we often refer to? This article will introduce this ball screw in detail for the majority of users.
1. SFU1605 Ball Screw Features
When we usually select models with customers, we will ask customers about load, stroke, positioning accuracy, horizontal or vertical direction of use, and speed requirements.
SFU: Indicates the type of the screw, usually used to identify the ball screw series.
16: Represents the diameter of the screw
05: SFU1605 ball screw pitch, which is also the lead of the screw, that is, for every turn, the nut of the screw moves 5 mm along the screw.
The larger the diameter of the screw, the greater its load capacity, and the larger the lead of the screw, the faster its speed.
2. How to Install the Ball Screw Nut?
Methods for installing balls on ball screw nuts:
- Clean the ball screw nut and balls.
- Put the plastic ball retainer (ball reverser) back into the nut. When installing the ball retainer, pay attention to the smooth connection between the ball retainer ball inlet and outlet and the spiral groove.
- Apply grease to the nut.
- Put the ball into the spiral groove. Note that not all spiral grooves are filled. The ball is placed according to the principle that one ball retainer is a circulation garden. I see that your nut seems to have 4 ball retainers, which means 4 circulation gardens. ⑤Screw the nut into the screw (be careful not to drop the ball).
- Rotate the nut forward and backward to check whether the nut runs smoothly.
3. Application of SFU1605 Ball Screw
CNC machine tools: Ball screws are used to control the movement of tools to achieve precision machining.
Automation equipment: It is used for linear drives in robots, conveyor belts and other equipment.
3D printers: It is used to control the movement of print heads or platforms.
Medical equipment: It is also used in some high-precision medical devices.
4. Maintenance of Ball Screws
Cleaning
Ball screws are easily affected by impurities such as dirt, dust, grease, etc., which can affect the normal operation of the ball screw. Therefore, the ball screw needs to be cleaned regularly.
Lubrication
The sfu1605 ball screw needs to be refueled or greased regularly, so how to grease the ball screw?
First, wipe the surface of the ball screw with a clean cloth to remove dust and dirt and ensure that there are no foreign objects.
Then use a grease gun or applicator to evenly apply grease to the contact surface of the ball screw thread and the nut. If there is a grease hole, inject grease into the hole through a grease gun until the grease begins to overflow from the gap of the nut.
Manually rotate the ball screw for several turns to ensure that the grease is evenly distributed throughout the thread and inside the nut.
Finally, wipe off the excess grease with a clean cloth.
Generally, for high-speed and high-temperature ball screws, lubricating oil can be selected; for low-speed, high-load, and high-sealing ball screws, grease is more suitable.
Protection
During work, the sfu1605 ball screw is easily affected by impurities, debris and other substances, causing problems in its internal structure. Therefore, appropriate measures need to be taken to ensure that its surface is clean and smooth.
Summary
SFU1605 ball screw is a high-efficiency and precise mechanical transmission element, which is widely used in various automation and precision mechanical equipment. Its superior performance makes it one of the indispensable components in modern industry.
