The Kukko 20-40-B hydraulic puller offers a great solution for extracting large components in various applications. It features cross-legged jaws that remain securely suspended within the slider, ensuring a firm grip. The improved jaw geometry allows for smooth adjustments along the cross-beam, simplifying operation. A two-sided spindle tip enhances adaptability by optimizing contact with different shaft types, further improving usability.

This tool incorporates grease hydraulics and a combination of hydraulic and mechanical pressure screws to facilitate controlled force application. The standard pulling hook and parallel pulling hooks maintain their position under full load, offering consistent performance. This hydraulic bearing puller has adjustable pulling hooks provide flexibility, enabling precise adaptation to different workpieces. A milled thread with a specialized coating enhances durability, while the two-arm configuration supports use in confined spaces.

This hydraulic gear puller accommodates various extraction needs, including asymmetric workpieces, by allowing internal and external pulling through reversible hooks. Its hexagonal cross-beam profile supports secure handling, and a spindle head band prevents slippage for reliable torque application. Optional jaw extensions increase reach, while interchangeable jaw types offer mechanical conversion options. Designed for long-term use, the Kukko 20-40-B hydraulic puller benefits from self-healing corrosion protection, readily available replacement parts, and a sturdy construction that ensures extended service life.
