3-Jaws Gear Puller (CrV, Hydraulic) - Product Detail Page

1. Product Specifications

2. Product Details

• Dual-Jaw Versatility: It supports both 2-jaw and 3-jaw configurations. The 3-jaw setup delivers balanced clamping force for round/cylindrical parts (e.g., gears, bearings), while the 2-jaw mode adapts to irregularly shaped components or tight spaces, meeting diverse work needs.
• Ergonomic & Space-Saving Design: Equipped with a removable handle and 360-degree pressure direction adjustment. The removable handle reduces storage space, and the adjustable pressure direction allows easy operation in restricted areas (e.g., narrow machine compartments) where traditional pullers are hard to maneuver.
• High-Safety Hydraulic Cylinder: The hydraulic cylinder features a one-piece solid steel molding design. This structure eliminates weak points from assembly, enhancing pressure resistance and preventing oil leakage or cylinder deformation under heavy loads, ensuring a high safety factor during use.
• CrV Steel Durability: Key components (including jaws and connecting parts) are made of CrV (Chrome-Vanadium) steel. CrV steel offers excellent toughness and wear resistance, and after precision processing, it ensures the puller can withstand long-term high-tension use without damage.

3. Application Scenarios

• Heavy-Duty Machinery Maintenance: Ideal for factories maintaining large machinery (e.g., industrial motors, steel rolling machines, and mining equipment). It can pull out large gears, bearings, or hubs from machine shafts, even under high interference fits, minimizing equipment downtime.
• Automotive Heavy-Duty Repair: Suitable for repairing commercial vehicles (e.g., trucks, buses) or construction vehicles (e.g., excavators, loaders). It disassembles large components like transmission gears, axle bearings, and clutch hubs, which require high pulling force beyond manual tools.
• Marine Equipment Servicing: Used in shipyards or marine maintenance facilities to service ship engines, propeller shafts, or pump systems. The puller’s corrosion-resistant properties and high load capacity handle the harsh marine environment and heavy marine components.
• Power Generation Equipment Maintenance: Applied to maintain power plants (e.g., thermal power, hydropower) for disassembly tasks on turbine components, generator rotors, or large pump bearings. Its stable performance ensures safe and efficient maintenance of critical power equipment.
