Needle bearing extractor - Kukko Quality Tools Inc

The Kukko 21-46 Needle Bearing Extractor is a professional-grade tool meticulously engineered for the clean and controlled removal of needle bearings, pilot bearings, and similar components from housings and blind bores. Designed for rigorous daily use in demanding automotive and industrial environments, this German-made tool ensures a secure grip and precise extraction, minimizing the risk of damage to surrounding shafts and housings.

Key Features

• Internal Grip Design: Features a robust 2-shell design with extra-large grasp edges, ensuring a secure grip for extracting needle bearings and pilot bearings from blind holes within a diameter range of 20-25 mm.
• Durable German Construction: Manufactured from quality high-grade hardened steel in Germany for exceptional durability, high performance, and extended service life under extreme pulling loads and repeated shop use.
• Precision and Safety: The precision jaws expand securely behind the bearing, providing a reliable, slip-resistant grip. An integrated internal safety stop protects against excess spreading and overloading, enhancing tool longevity and operational safety.
• Controlled Pulling Mechanism: Utilizes a screw-type pulling mechanism, or is compatible with common counter supports and slide hammer sets, to provide controlled, non-impact removal, protecting sensitive components from damage.
• Compact Profile: Engineered with a compact design for optimal access in confined engine bays, transmission cases, and differential housings.

Applications

The Kukko 21-46 Needle Bearing Extractor is an indispensable service tool for professional mechanics, transmission rebuilders, and industrial maintenance teams. It is ideal for removing needle roller bearings and similar press-fit components from critical assemblies such as engine blocks, transmission cases, gearboxes, and driveline components. Common applications include extracting pilot bearings from crankshafts, needle bearings from transfer cases and differentials, and small bushings or sleeves from housings where access is limited to one side, providing a precise method for internal bearing removal without resorting to destructive techniques.
