High-Lead Screw Jacks: Optimizing Lifting Speed and Efficiency

Compact Design – Superior Performance for Automation

Designed specifically for applications demanding high speed and efficiency, the High-Lead (Quick-Action) Screw Jack series from Nippon Gear Maker provides a lifting solution that is compact and lightweight yet offers vastly superior operation compared to standard screw jack types.

Technological Highlights and Customer Benefits

1. Ultra-Fast Lifting Speed (2x – 5x)

• Advanced Screw Technology: The product uses a quadruple-thread lead screw combined with a special high-lead pitch.

• Operational Efficiency: Thanks to this design, the lifting speed is 2 to 5 times faster than standard screw jacks (at the same input shaft speed), making it ideal for fast automation systems.

2. Optimized and Flexible Design

• Compact Size: The optimized design helps save valuable installation space in the production line.

• Multi-Directional Mounting: Smart mounting holes allow you to mount the jack on both the top or bottomof the equipment, increasing flexibility in system design.

• Load Capacity: Suitable for light and medium load ranges: 2kN / 5kN / 10kN.

3. Control and Protection Options

Despite their compact size, high-lead screw jacks can still be equipped with essential options:

• Protection: Dust-proof bellows (helps protect the lifting screw from dirty environments).

• Control: Limit Switch (for stroke control), RC Encoder (ensures positional accuracy in synchronized systems).

IMPORTANT SAFETY WARNING

Non-Self-Locking Function:

Due to the use of a high-lead screw pitch to maximize speed, this type of screw jack does not have a self-locking function (Non-Self-Locking). This means the load may slide down when the motor stops.

It is mandatory to install a Safety Brake or use an appropriate motor braking system during installation to ensure absolute safety for personnel and equipment.

Ideal Applications

High-lead screw jacks are the perfect choice for:

• High-speed lifting/lowering tables.

• Fast positioning systems in assembly lines.

• Actuators requiring quick response in automated environments.
