Read the manufacturer’s instructions for your specific table saw model and familiarize yourself with its parts and components.
Note: The following steps provide a general guideline for replacing table saw arbor bearings. However, it’s crucial to consult your table saw’s manual or seek professional advice, as the process may vary depending on the make and model of your saw.
Essential Steps for Replacing Table Saw Arbor Bearings
Table saw arbor bearings are essential components that enable smooth rotation of the saw blade. Over time, these bearings may wear out or become damaged, resulting in decreased performance and potentially hazardous operating conditions. Replacing table saw arbor bearings is a necessary maintenance task that should be carried out with precision and care.
Step 1: Safety Precautions
Before you begin any work on your table saw, it is vital to ensure your safety. Make sure to disconnect the power supply and wear appropriate protective gear, such as safety glasses and gloves.
Step 2: Removing the Blade and Arbor Assembly
The first step in replacing the arbor bearings is to remove the blade and the arbor assembly. This typically involves loosening the arbor nut and carefully sliding off the blade. Refer to the manufacturer’s manual for specific instructions.
Step 3: Disassembling the Arbor Assembly
Once the blade and arbor assembly have been removed, disassemble the arbor assembly to access the bearings. This may involve removing any retaining nuts or screws that are holding the assembly together. Take care not to damage any surrounding components.
Step 4: Removing the Old Bearings
With the arbor assembly disassembled, it is time to remove the old bearings. This can typically be done by pressing out the bearings from their housing using a bearing puller or a similar tool. Take note of the orientation of the bearings for easier installation of the new ones.
Step 5: Installing the New Bearings
Once the old bearings have been removed, it is time to install the new ones. Apply a thin layer of bearing grease to the new bearings and carefully press them into their respective housing using a bearing driver or a similar tool. Ensure that the bearings are properly seated and aligned.
Step 6: Reassembling the Arbor Assembly
After successfully installing the new bearings, carefully reassemble the arbor assembly. Ensure that all components are properly aligned and secured. Follow the manufacturer’s guidelines for torque specifications when tightening any nuts or screws.
Step 7: Reattaching the Blade and Arbor Assembly
Finally, reattach the blade and arbor assembly to the table saw. Ensure that the arbor nut is tightened to the appropriate torque specification. Double-check that all connections are secure before proceeding.
By following these essential steps, you can successfully replace the table saw arbor bearings and restore the optimal performance of your table saw. Remember to consult the manufacturer’s manual for any specific instructions and always prioritize safety throughout the process.

Replacement Arbor Bearings
When purchasing replacement arbor bearings, make sure to get the correct size and type for your table saw model. The bearings should be of high quality and designed to withstand the rigors of heavy-duty use. It is recommended to consult the user manual or contact the manufacturer for the exact specifications and part numbers of the bearings.
Thread Locker and Grease
Thread locker is used to secure the arbor shaft and nut in place to prevent them from loosening during operation. It is important to use a high-strength thread locker that is compatible with the materials of the arbor shaft and nut.
Grease is required for lubricating the arbor bearings and ensuring smooth operation of the table saw. It is recommended to use a high-quality, high-temperature grease that is specifically designed for bearing applications.

Removing the Old Arbor Bearings
Before you can replace the arbor bearings on your table saw, you will need to remove the old bearings. Here are the steps to follow:
- Unplug the table saw from the power source to ensure your safety.
- Remove the table saw’s blade and raise the blade arbor to its highest position.
- Use a wrench to loosen the set screws that hold the blade arbor pulley in place. Once the set screws are loose, you can easily slide the pulley off the arbor.
- Inspect the arbor retaining nut and use a wrench to loosen and remove it from the arbor.
- Next, remove the arbor flange by unscrewing the screws or bolts that hold it in place.
- Once the arbor flange is removed, you can access the old bearings. Use a bearing puller or a hammer and a wooden block to gently tap the outer race of the bearing until it slides off the arbor shaft.
- To remove the inner race of the bearing, use a punch or a screwdriver to carefully pry it off the arbor shaft.
- Repeat the same steps for removing the other bearing on the opposite side of the arbor shaft.
With the old arbor bearings successfully removed, you can now proceed to install the new bearings and complete the replacement process.
Installing the New Arbor Bearings
Once you have removed the old arbor bearings from your table saw, it is time to install the new ones. Follow these steps to safely and correctly install the new arbor bearings:
Step 1: Inspect the New Bearings
Before installing the new arbor bearings, carefully inspect them to ensure they are in good condition and free from any defects. Look for any signs of damage or wear that may affect their performance. If you notice any issues, it is best to replace them with new ones.
Step 2: Prepare the Bearings and Arbor
Start by cleaning the arbor shaft and ensuring it is free from any debris or dirt. This will help the new bearings fit properly and function smoothly. Additionally, apply a thin layer of lubricant to both the arbor shaft and the inner race of the new bearings to promote easy installation and reduce friction.
Step 3: Align and Press in the Bearings
Align one of the new bearings with the arbor shaft and gently press it into place. Make sure it is seated properly and fully on the shaft. Repeat this step for the other bearing, ensuring it is aligned correctly as well.
Note: It is essential to use a proper bearing installation tool or a bearing press to avoid damaging the bearings or the arbor shaft during the installation process.
Step 4: Check for Proper Alignment
After the bearings are installed, check for proper alignment. Spin the arbor shaft to ensure it rotates smoothly and without any wobbling. If you notice any issues, it may indicate a misalignment or an improperly installed bearing. In such cases, remove the bearings and repeat the installation process.
Step 5: Secure the Arbor Assembly
Once the new arbor bearings are installed and aligned correctly, secure the arbor assembly back into its housing. Follow the manufacturer’s instructions for tightening the arbor nut or any other securing mechanism. Ensure that everything is tightened securely but not overly tight to allow smooth operation.
With the new arbor bearings properly installed, your table saw should now be ready for use. Enjoy the improved performance and precision that the new bearings provide!
Testing and Fine-Tuning the Repair
Once you have replaced the arbor bearings on your table saw, it is important to test the repair to ensure everything is functioning properly. Here are some steps to follow:
- Reassemble the table saw by putting all the parts back in their proper places.
- Make sure that all the bolts and screws are tightened securely.
- Turn on the table saw and listen for any unusual sounds or vibrations. If you hear anything out of the ordinary, turn off the saw immediately and recheck your work.
- Observe the blade as it runs to make sure it is spinning smoothly and not wobbling. A wobbling blade may indicate that the arbor bearings need further adjustment or replacement.
- If everything appears to be in order, test the saw by making a few cuts on some scrap wood. Pay attention to the accuracy and smoothness of the cuts.
- If you notice any issues during the testing process, it may be necessary to fine-tune the repair. This could involve adjusting the arbor bearings, checking the alignment of the blade, or inspecting other components of the saw.
Remember, safety should always be your top priority when working with power tools. If you are unsure about any aspect of the repair process, it is best to consult a professional or seek guidance from the manufacturer.
