SFT Series Ball Screw

SFT Series Ball Screw

Product descriptions

The SFT Series Ball Screw is a high-performance linear actuator that efficiently converts rotational motion into precise linear motion. Its design features a single, flange-style nut and an innovative "end plug" internal ball circulation system, creating a compact and economical solution for a wide range of automation needs.

Performance and Specifications

The SFT series serves as an economical choice, meeting industry standards while fulfilling the requirements of most feeding equipment.

Manufacturing Process: This series offers two manufacturing processes for customer selection: rolling and grinding.

Accuracy Grades: The SFT series complies with ISO and JIS accuracy standards, with precision levels ranging from C3 to C10 available.

Preload Options: To meet varying application requirements for rigidity and clearance, the SFT series provides multiple preload levels ranging from zero preload with clearance (P0) to light preload with zero clearance (P2).

Material: Typically manufactured from GCr15 carbon steel.

Key Features and Advantages

The SFT Series is engineered for modern machinery, emphasizing efficiency, precision, and user-friendliness.

Compact Footprint: The micro-diameter design and internal ball circulation create a space-saving unit, making it ideal for compact linear systems.

High Efficiency and Low Friction: Rolling ball bearings ensure minimal friction, providing superior transmission efficiency compared to conventional sliding screws and reducing the required drive power.

Zero Backlash and High Rigidity: The ball screw assembly can be preloaded to eliminate backlash. This results in high stiffness and ensures precise, repeatable positioning for applications demanding superior accuracy.

Smooth and Quiet Operation: The end plug circulation system provides a smooth pathway for the ball bearings, leading to stable and quiet performance, even at high speeds.

Simple Maintenance: A conveniently located oil inlet on the nut allows for easy lubrication, which is crucial for maintaining optimal performance and extending the service life of the unit.

Economical and Reliable: As a cost-effective model, the SFT series meets the demands of most feeding and transport devices without sacrificing quality or performance.
