Product Information
Full details
This 3-jaw pilot bearing puller from US PRO Tools is designed for mechanics and DIY enthusiasts needing to remove pilot and inner sleeve bearings from various automotive and industrial applications. Its key benefit is the controlled, even pressure applied by its three jaws, reducing the risk of damage to sensitive components. A potential caveat is its specific diameter range, making it unsuitable for bearings outside 17mm to 50mm.

FAQs
What is the minimum and maximum bearing diameter this puller can handle?
This puller is designed to work with sleeve-type bearings ranging from 17mm to 50mm in diameter.
Can this tool be used for external bearings?
No, this puller is specifically designed for the removal of pilot and inner sleeve bearings.
How does the 3-jaw system benefit bearing removal?
The 3-jaw system applies even pressure across the bearing surface, ensuring controlled removal and minimizing the risk of damage to the bearing or surrounding components.
What types of bearings is this puller suitable for?
It is suitable for pilot bearings and inner sleeve-type bearings.
What maintenance is required for this tool?
After use, clean the jaws and screw threads. Periodically apply a light lubricant to the screw threads to ensure smooth operation and prevent rust.
Is this tool suitable for very large or very small bearings outside the specified range?
No, the tool is specifically calibrated for bearings within the 17mm to 50mm diameter range. Using it outside this range may lead to poor performance or damage.
Troubleshooting
Jaws will not grip the bearing securely
Ensure the bearing diameter is within the 17mm-50mm range. Verify that there is a suitable edge or lip on the bearing for the jaws to firmly grasp. Check for any obstructions or damage on the bearing surface that might prevent a good grip.
Puller is difficult to tighten or operate
Clean the central screw threads and apply a light lubricant. Ensure the jaws are properly aligned and not binding against each other or the component.
Bearing is not extracting evenly
Re-center the puller on the bearing and ensure all three jaws are applying equal pressure. Tighten the central screw incrementally, checking for even movement.
Puller appears to be flexing under pressure
Confirm the bearing diameter is within the specified range. If the bearing is particularly seized, consider using a penetrating lubricant and allowing it time to work before applying further force. Ensure you are using the puller for its intended purpose and not exceeding its design limits.
