Three-arm puller NEO tools Three-arm puller 12" — workshop extraction tool for bearings and gears

NEO tools Three-arm puller 12" is a mechanical extraction tool designed to remove bearings, gears, pulleys and other press-fit parts. The three-arm (three-jaw) configuration ensures a balanced grip around the component, allowing even distribution of pulling force to reduce the risk of damage. The 12" designation refers to the maximum span between opposing arms, making this puller suitable for a range of medium to large components commonly encountered in automotive and workshop maintenance.

Advantages

The three-arm design provides stable, centered pulling action for cylindrical and irregularly shaped parts. Hardened, shaped jaws offer secure contact with components while the central forcing screw transmits controlled mechanical force. Durable construction and corrosion-resistant finish ensure reliable performance in workshop environments. The tool's span and adjustability permit use on a variety of shaft diameters and part sizes without requiring improvised adapters.

Suitable for

• Removing wheel bearings and hub assemblies
• Extracting gears from shafts in automotive and industrial applications
• Pulling pulleys, couplings and similar press-fit parts during maintenance
• Machinery servicing and general workshop disassembly tasks

Key specifications

• Three-arm (three-jaw) configuration for balanced gripping
• Maximum span: 12 inches (approx. 305 mm)
• Central forcing screw for controlled mechanical extraction
• Adjustable arm positions to accommodate different part diameters
• Hardened contact surfaces on the jaws for improved durability

How to use

Position the puller arms evenly around the component to ensure a centered grip. Adjust the arms so the jaws engage securely behind the part to be removed. Turn the central forcing screw using an appropriate wrench or socket, applying steady, even force until the component is freed from the shaft or housing. If resistance is high, check alignment and re-seat the jaws rather than applying excessive torque. Use appropriate safety measures such as eye protection and secure the workpiece before extraction.

Usage recommendations

For best results, clean contact surfaces and inspect jaws for wear before use. Use penetrating oil on stuck parts when appropriate and apply steady, incremental force with the central screw. Avoid sudden impacts that can damage both the tool and the workpiece. Store the puller in a dry place to prevent corrosion and periodically check threads and jaw condition to maintain safe operation.
