- Modular tool system The kit covers every step of bearing maintenance with a modular design. It enables precise inner and outer ring work and coordinates multiple tools to fit a range of bearing sizes without adding complexity. - Adjustable jaws Three jaw setup with adjustable spacing to fit inner and outer rings of many bearings. Provides secure grip across a wide size range and reduces risk of slip. - Enhanced separation process Hammer assisted separation maintains steady pulling force and allows uninterrupted impact operation. Efficiently transfers shock to the bearing to reduce manual effort and protect components. - Reinforced puller hooks Reinforced hooks and a sturdy frame distribute force evenly. Prevents slipping and minimizes damage during removal for consistent results. - Durable construction and compatibility Made from high strength steel for reliability. Compatible with common automotive, industrial and agricultural bearings and hubs. - Applications Automotive wheel hubs, industrial gearboxes, farm equipment hubs.
