Description:
This heavy-duty bearing puller set is built for workshop use where removing stubborn bearings or seals without damaging the inner races is required. It combines a dual-chuck separator design with multiple extension screws and legs to handle a wide range of bearing diameters, offering practical leverage for mechanics and hobbyists alike.
Key Points
The kit is organized in a high-strength plastic case that keeps components secure and easy to transport. It includes separator jaws in two sizes and a six-inch yoke that work together to extract graphite and silicon carbide bearings safely, reducing the likelihood of inner-race damage. The tools have a chrome-plated finish and undergo heat treatment and anti-rust processing for increased hardness and longer service life. ⚙️
The high-torque screw design helps save effort when pulling bearings, making the set suitable for repetitive tasks in an automotive or industrial maintenance environment. Note that installation instructions are not included, so basic mechanical knowledge is helpful when assembling and using the components.

Benefits
Using this set reduces the risk of damaging inner bearings during removal, according to the manufacturer, because the separator jaws support even pressure distribution around the bearing. The variety of extension screws and legs permits adjustable reach and different puller configurations, which increases versatility for shafts and housings of varying depths. The chrome finish and thermal treatment increase resistance to wear and corrosion, which helps maintain tool geometry and performance over time. 🛠️
Consider that the maker’s parts list repeats one size of 4-inch extension screws, and some items may require user judgment to configure correctly for a particular extraction. Also keep in mind that because instructions are not provided, assembly can be slower for less experienced users.
Usage Recommendations
Start by selecting the separator jaw that fits most closely to the bearing outer diameter and mount it squarely to avoid tilting. Use the yoke and forcing screw with gradual, even turns to apply force, checking alignment frequently so the inner race is not contacted. For deeper or hard-to-reach bearings, add extension screws incrementally rather than forcing a long extension in one step. Wear safety glasses and gloves while working to protect against sudden slips or part ejection.
