The Kukko 20-40-AV heavy duty gear puller is designed for extraction jobs, handling large components such as bearings, gears, and discs. Manufactured in Germany, it features a robust two-arm design, ensuring stability in confined spaces. The individually adjustable spread and reach provide versatility across various applications, while a mechanical pressure screw enhances force distribution. A two-sided spindle tip allows optimal adjustment to different shafts, increasing precision and effectiveness.

This big bearing puller incorporates standard pulling hooks with adjustable depths, ensuring adaptability for diverse workpieces. Parallel pulling hooks remain stable under full load, while their infinitely variable adjustment on the cross-beam allows for customized configurations. The pulling hooks can be rotated for both internal and external use, making the tool suitable for asymmetric components. A large bearing puller must handle significant force, and this model’s high-performance design withstands tough conditions. Its milled thread, treated with a specialized coating, ensures smooth operation and durability. It also benefits from a spindle head band that prevents wrench slippage, improving control and safety during extraction.

 A safety label safeguards intellectual property, while the included special grease optimizes pressure spindle performance. With nearly all components available as replacements and a clear numbering system for quick part identification, this tool ensures reliability and ease of maintenance. The Kukko 20-40-AV heavy duty gear puller features self-healing corrosion protection on galvanized parts.
