Tips for Assembling Ball Screws with Dropped Balls
2. Block one end of the sleeve: Seal one end of the hollow sleeve with a soft material (such as foam packaging). Insert the sleeve into the cleaned nut (with no balls inside).
3. Load the balls: Fill the balls into each circular groove one by one. After filling a full circle (leave a gap equivalent to 0.5-1.5 ball diameters), gently rotate the hollow sleeve to ensure smooth movement. Then push the sleeve forward to load the next circle of steel balls, repeating until all grooves are filled.
4. Remove the blocking material: Take out the filler from the end of the sleeve. Slide the sleeve (with the nut attached) over the end of the linear ball screw shaft.
5. Install the nut onto the linear motion screw: Hold the hollow sleeve firmly with one hand and slowly screw the nut onto the ball screw kit with the other hand until the nut smoothly engages the entire effective thread raceway of the ball screw set.
6. Lubricate and test: Inject grease or lubricating oil through the nut’s oil hole. Rotate the nut to move it back and forth for at least 2 full strokes to confirm smooth operation. Finally, inject lubricating grease once more to complete the process.
Hojama ball screw assemblies will be installed before shipment and we will give them a full inspection to ensure the quality of the product.

First and foremost, it must be emphasized that users are not recommended to disassemble or install the nut by themselves, especially for high-Precision Ball Screws. If the balls in the nut accidentally fall out or the nut has already been disassembled, it is best to send it back to our company for after-sales maintenance. If urgent use is required, please follow the steps below to reinstall the nut.
Â
1. Prepare a hollow sleeve: Fabricate a hollow sleeve with an outer diameter slightly smaller than the ball screw raceway diameter (about 0.1mm smaller) and an inner diameter slightly larger than the outer diameter of the ball screw end. The length of the sleeve should be slightly longer than the nut.
