LONGLOOD Hydraulic Self-Centering Puller for Bearing and Gear Removal

The LONGLOOD Hydraulic Self-Centering Puller Kit is a professional heavy-duty pulling solution designed for the safe and efficient removal of bearings, چرخ دنده ها, pulleys, bushings, and other press-fitted components.

Featuring an advanced three-jaw linkage self-centering system, the puller automatically adjusts the jaws to maintain balanced pulling force and ensure accurate positioning. The hydraulic system provides powerful and controlled pulling force up to 700 نوار, reducing manual effort while improving safety and efficiency.

Built with high-strength alloy steel and equipped with a stable support base and omni-directional wheels, this hydraulic puller delivers excellent durability, mobility, and reliability for industrial maintenance applications.

Product Features

Automatic Three-Jaw Self-Centering Design

The three-jaw linkage system allows automatic centering during operation, ensuring the pulling force is evenly distributed around the component.

This design improves pulling accuracy, reduces setup time, and minimizes the risk of damage to shafts and parts.

High-Strength Alloy Steel Construction

Manufactured from high-strength alloy steel, the puller provides excellent strength, مقاومت در برابر سایش, and long service life even under demanding industrial conditions.

The heavy-duty structure ensures stable performance during high-force pulling operations.

Powerful Hydraulic Operation

With a maximum working pressure of 700 نوار, the hydraulic system delivers strong and precise pulling force for removing difficult press-fitted components.

Hydraulic control provides smoother operation compared with traditional mechanical pullers.

Stable Base Support Design

The large support pad provides a stable foundation for the hydraulic cylinder, improving safety and reducing movement during operation.

This design ensures better force transmission and reliable pulling performance.

Easy Mobility with Omni-Directional Wheels

Integrated wheels allow easy transportation and positioning of the puller, making it suitable for workshop and field maintenance applications.

Operators can quickly move and adjust the tool according to different working conditions.

Hydraulic Pressure Self-Locking Safety System

The hydraulic control check valve maintains pressure stability and prevents sudden pressure release during operation.

This safety feature improves operator protection during heavy-duty pulling tasks.

Easy Maintenance and Service

The hydraulic cylinder and pump assembly can be easily disassembled, simplifying maintenance and allowing flexible use across different applications.
