Shafts and supports for linear motion technology – guides for linear bearings and bushings

Linear shafts and supports form the foundation of precise guidance in linear motion technology. A properly selected guide shaft and shaft supports ensure stable motion geometry, limit guide deflection, and allow the full capabilities of components such as linear bearings and rolling bushings to be utilized.

Application and characteristics

In practice, guide shafts are used in industrial automation, CNC machinery, assembly workstations, transport systems, and wherever smooth reciprocating movement and repeatable axis positioning are required. Selecting the right guide based on loads, axis length, and support type is of crucial importance.

Most frequently, you will find:

• unsupported shafts – for shorter axes or systems where the design provides sufficient rigidity,
• supported shafts – guides supported along their entire length, which limit deflection over longer distances and under heavier loads,
• shaft support rails and shaft end supports – mounting elements that stabilize the system and facilitate correct axis alignment,
• material executions tailored to the working environment, e.g., corrosion-resistant variants or those with enhanced surface resistance.

When selecting a shaft + support assembly, it is essential to consider the guide diameter, axis length, expected loads, and environmental conditions. It is the complete alignment of the guide with the linear bearings (e.g., open-type bushings for supported shafts) that directly impacts the service life and smooth operation of the entire system.

Key advantages

• Higher guiding rigidity – particularly in systems utilizing supported shafts.
• Enhanced motion precision – stable axis geometry and positioning repeatability.
• Reduced deflection and vibration – highly beneficial in dynamic CNC and automation applications.
• Easier installation – supports and brackets assist in the correct alignment of the guide.
• Compatibility with linear bearings – a cohesive assembly of shaft + linear bushings/bearings.
