Installation of ball screw bearings:
Precise installation of ball screw bearings plays a crucial role in the longevity and efficiency of your CNC machines. Improper handling can cause damage, impair functionality, and ultimately result in expensive repairs.
Step 1: Cleaning the bearing surface
To ensure optimal performance of your ball screw bearings, we recommend removing all manufacturer's rust-preventing oil. This is best accomplished with brake cleaner or thinner , as these effectively remove dirt and oil residue.
Step 2: Remove residue
After cleaning, you should dry the bearings thoroughly with compressed air.
Danger:
Never rotate the bearings using air pressure, as this may cause mechanical damage.
Step 3: Avoid over-fatting
A common mistake when installing ball screw bearings is excessive grease. Avoid completely filling the bearings with grease.
Why?
Over-greasing can lead to excessive heat build-up, which significantly shortens the lifespan of both the grease and the bearings.
Step 4: Follow the manufacturer's instructions
If you are unsure how to correctly install ball screw bearings, we recommend consulting the instructions provided by your machine manufacturer or CNC dealer . You will receive detailed information specific to your machine.
Common installation mistakes and how to avoid them
Error 1: Insufficient cleaning of the bearing surface
If residues of the rust-protection oil remain, the grease will not adhere properly, which will impair the lubricating effect.
Error 2: Improper handling of compressed air
Rotating the bearings with air pressure leads to mechanical damage and increased wear.
Mistake 3: Wrong amount of fat
Too much or too little grease can negatively affect bearing performance. Use exactly the amount specified in the manufacturer's instructions.
Tips for extending the life of ball screw bearings
1. Regular inspection and maintenance
Check bearings regularly for wear and other damage.
2. Use of high-quality lubricating grease
Only use lubricants that meet the manufacturer's specifications.
3. Protection against contamination
Keep the bearings free from dirt, dust and moisture during installation and operation.
Conclusion: The right approach makes the difference
Installing ball screw bearings requires precision and attention. By following the steps above, you can extend the life of your bearings and optimize the performance of your CNC machine.
Frequently Asked Questions (FAQs)
1. Which cleaning agent is best for ball screw bearings?
We recommend brake cleaner or thinner as these products effectively remove rust inhibitor oil and contaminants.
2. How much fat should be used?
Follow the manufacturer's instructions. Over-oiling is just as harmful as under-oiling.
3. Can I install the bearings myself?
If you have no experience, contact the machine manufacturer or a CNC dealer for detailed instructions.

What does the suffix mean
The expert's advice
RS, 2RS, 2RSH, 2RS1, RSR, 2RSR, E, EE, LLU, LLB, DU, DDU
These suffixes indicate whether the bearing is equipped with one or two rubber seals. For 123 ball bearings, the number 2 indicates that the bearing is sealed on both sides.
C3, C4
Indicates increased internal clearance. Often referred to as high-speed capability, this indicates that the bearing is designed for high speeds and moderate temperatures. Caution: A bearing with increased internal clearance will not perform optimally at low speeds. We recommend consulting the technical data sheet for the bearing in question to verify the speed limit.
ZZ, 2Z, ZR, Z
These suffixes indicate whether the bearing is equipped with one or two metal baffles for dust protection. For 123 ball bearings, we mark whether the bearing is sealed on both sides with ZZ seals.
TN9, TVH, TVP, G15
These suffixes indicate that the cage that keeps the balls spaced apart in the bearing is made of polymer material, usually glass fiber reinforced polyamide.
ABEC
The ABEC standard is used to classify bearings based on their machining tolerances. However, it is often criticized for not taking into account certain critical technologies that ensure a bearing's functionality, efficiency, and service life. Therefore, 123Kugellager does not use this standard.
BHT / VT
This suffix indicates that the bearing is designed for very high operating temperatures. The exact temperature is usually indicated after this suffix. Caution: These bearings are not suitable for all applications and require high temperatures to ensure optimal service life.
