Product Description:

PFDW Series Ball Screw is designed with a preloaded internal structure to eliminate clearance and enhance motion consistency. The series focuses on reducing mechanical play, improving directional response, and maintaining uniform linear output. It is suitable for systems requiring precise force response and stable bidirectional movement.

Specification:

PFDW-1PFDW-2

Advantages:

1. Zero clearance performance

Preloaded design effectively eliminates axial play.

2. Improved motion consistency
Maintains uniform linear response during direction changes.

3. Enhanced positional reliability
Supports stable control in repeated start-stop operations.

4. Smooth bidirectional transmission
Ensures controlled movement without delay or slack.

5. Reliable performance under precision demands
Designed for applications sensitive to motion deviation.


Features:

1. Preloaded ball screw assembly

2. Zero-clearance linear transmission

3. Reduced mechanical compliance

4. Consistent force response behavior

5. Designed for precision-driven systems


Applications:

1. Precision positioning modules

2. Servo-driven linear systems

3. Industrial automation requiring zero play

4. Tool alignment and adjustment units

5. High-consistency motion platforms

6. Bidirectional control mechanisms
