S6000 FK/FF08-40 Precision Ball Screw End Support for Industrial Use

FKFF Series Ball Screw Support Units – Introduction & Advantages

The FKFF Series is a high-precision, compact support unit specially designed for ball screws. It provides stable axial positioning, rigid support, and smooth rotation for precision machinery and automation equipment.

Product Features

Compact and integrated structure

High concentricity, high rigidity, and easy installation.

High-performance angular contact bearings

Capable of withstanding combined radial and axial loads.

Fixed side (FK) and floating side (FF) design

FK provides fixed support with high rigidity; FF acts as a floating support to compensate for thermal elongation of the screw shaft.

High precision and low runout

Ensures stable transmission accuracy and smooth rotation.

Standardized dimensions

High interchangeability, easy to assemble and maintain.

Built-in sealing and lubrication system

Prevents dust and coolant contamination for long service life.

Product Parameters

Core Advantages

1. High rigidity and high stability

Effectively reduces deflection and improves overall system precision.

2. Thermal elongation compensation

The floating side (FF) absorbs thermal expansion, protecting the ball screw.

3. Easy installation and high compatibility

Suitable for most general ball screws with no complex adjustment required.

4. High precision and low noise

Stable operation, low vibration, and low noise during high-speed rotation.

5. Long service life and high reliability

Good sealing performance reduces wear and extends maintenance cycles.

6. Cost-effective and widely applicable

Ideal for various automation and precision equipment.

Typical Applications

• CNC machine tools

• Precision positioning systems

• Semiconductor and testing equipment

• Laser processing machines

• Automation modules

• Medical and optical instruments
