What is a 3-jaw puller? Key notes for using a 3-jaw puller

A 3-jaw puller is an essential tool for every mechanical workshop, supporting the quick and safe removal of bearings and gears. At Naltako, we provide high-quality 3-jaw pullers, crafted from durable Cr-V steel, ensuring superior performance in automotive repair and machinery maintenance. With a flexible design and uniform pulling force, this product helps optimize mechanical work. Let’s explore in detail the 3-jaw puller and solutions from Naltako to enhance your work efficiency.

What is a 3-Jaw Puller and Its Uses?

A 3-jaw puller, also known as a triple-leg puller, is a specialized mechanical tool used to remove parts like bearings, ball bearings, gears, or pulleys from shafts or tightly fitted positions. This tool operates by using three jaws to create uniform pulling force, helping to remove components without causing damage. 3-jaw pullers are widely applied in automotive repair, industrial machinery maintenance, and production lines, bringing high efficiency to mechanical repair systems.

At Naltako, 3-jaw pullers are made from Cr-V (chromium-vanadium) steel, ensuring outstanding durability and load-bearing capacity. This product combines perfectly with equipment such as hydraulic pallet trucks or mini cranes, creating a comprehensive solution for assembly and disassembly work. For example, in automotive repair, a 3-jaw puller helps remove wheel hub bearings in just minutes, reducing time by 30% compared to manual methods. With 360-degree rotation capability, this tool is ideal for narrow spaces in industrial maintenance systems.

Common Types of 3-Jaw Pullers

3-jaw pullers on the market have many variations, each meeting specific needs in mechanical equipment systems. Common types include:

• Self-centering 3-jaw puller: Features a self-adjusting spring mechanism, ensuring balanced pulling force, suitable for small bearings.
• Hydraulic 3-jaw puller: Generates strong pulling force, ideal for large components like industrial gears.
• Symmetrical 3-jaw puller: Evenly spaced jaws, used for circular components like pulleys.
• Asymmetrical 3-jaw puller: Flexible for components with special shapes.

How to Use a 3-Jaw Puller to Remove Bearings

To remove bearings with a 3-jaw puller safely and effectively, follow these steps:

1. Preparation: Measure the bearing size and choose a suitable 3-jaw puller (75 mm – 300 mm).
2. Installation: Place the three jaws evenly around the bearing, ensuring a secure contact.
3. Alignment: Adjust the central pull bolt so the jaws grip the component tightly.
4. Apply Pulling Force: Use a wrench or hydraulic system to turn slowly to remove the bearing.
5. Inspection: Clean the component and tool after removal for long-term preservation.

Naltako provides 3-jaw pullers with a 360-degree rotating design, making operation easy in restricted spaces. Naltako’s self-centering 3-jaw pullers ensure uniform pulling force when removing automotive bearings, reducing the risk of component damage. Combined with freight elevators or scissor lifts, this tool makes the disassembly process faster and safer in industrial maintenance systems.

Choosing the Right Size 3-Jaw Puller

Choosing a 3-jaw puller that fits the size of the component to be removed is a key factor in ensuring work efficiency. Consider:

• Component size: Measure the diameter of the bearing or gear (50 mm – 300 mm) to choose the appropriate puller.
• Component type: Use a self-centering puller for small bearings, and a hydraulic puller for large components like pulleys.
• Working environment: Choose a 360-degree rotating puller if the space is narrow.

Safety Precautions When Using a 3-Jaw Puller

When using a 3-jaw puller, it is necessary to follow safety precautions to ensure occupational safety:

• Protective Gear: Wear safety goggles and gloves to prevent injury from debris or pulling force.
• Tool Inspection: Ensure the 3-jaw puller is not rusted and the jaws are secure before use.
• Regular Maintenance: Clean and lubricate the pull bolt after each use to maintain performance.
• Proper Operation: Pull slowly, avoid using excessive force to prevent damaging the component.

Naltako provides 3-jaw pullers with a safety design, integrating 360-degree rotating jaws and durable Cr-V steel, helping to reduce the risk of accidents in mechanical equipment systems. Naltako’s self-centering 3-jaw puller has a balanced spring mechanism, ensuring stable operation. Combined with forklift ramps, this tool supports safer and more efficient mechanical work.
