Linear bearings

Linear bearings for guide shafts in linear motion technology

Linear bearings are crucial components of linear motion technology that enable precise and smooth reciprocating movement along a guide rail with minimal friction. Combined with shafts and supports, they form reliable axis guiding systems in automation, CNC machinery, and production equipment where positioning repeatability and stable motion geometry are paramount.

Application and characteristics of linear bearings

This category includes solutions for building and modernizing guiding systems: from simple feed mechanisms to multi-axis systems in robotics and industrial automation. The most common variant is rolling bushings (including the linear ball bushing), where the recirculation of rolling elements ensures low travel resistance and high precision.

Depending on the design and mounting method, choices include:

• closed linear bearings – standard bushings for operation on unsupported shafts, frequently used in compact guiding assemblies,
• open linear bearings – designed for operation on supported shafts, where the application requires the guide rail to be supported along its entire length,
• flanged linear bearings – facilitate mounting and provide rigid fastening within the moving component,
• rolling bushings as a subcategory – solutions for precise shaft guidance in CNC and automation applications.

The selection of a linear bearing should be based on the shaft diameter, required loads, speed and stroke of movement, expected rigidity, and operating conditions (dust, moisture). In practice, it is the precise matching of the bearing to the shaft and supports that determines the durability of the guidance and the performance quality of the entire axis.

Key advantages

• Smooth movement and low friction – stable axis operation with low feed resistance.
• High guiding precision – enhanced repeatability in automation and CNC machinery.
• Various design executions – closed, open, and flanged options for different shaft and support configurations.
• Rigidity and stability – secure guidance of moving elements in multi-axis systems.
• Long service life – properly selected rolling bushings and linear bearings withstand intensive cyclic operation well.
