Linear Ball Guides | Motiontek

What Are Linear Ball Guides?

Linear ball guides, also known as linear guideways or linear motion bearings, are precision mechanical components designed to provide smooth and repeatable motion along a linear axis.
They use a recirculating ball structure, where hardened steel balls roll between precision-ground rails and blocks, dramatically reducing friction and eliminating stick-slip that occurs in traditional sliding systems.

Compared with plain bearings or bushings, linear ball guides deliver superior accuracy, high rigidity, and minimal wear — making them ideal for modern automation and CNC equipment.
The balls circulate inside the block through an optimized raceway, maintaining continuous contact with the rail while ensuring even load distribution and consistent performance.

Key Advantages

Motiontek’s linear ball guides are engineered for stability and precision under high-speed and high-load conditions.
They are available in multiple sizes from 15 mm to 65 mm, supporting both compact and heavy-duty industrial systems.

Main benefits include:

• Micron-level positioning accuracy
• Reduced friction and vibration for smoother operation
• High rigidity with four-direction equal load design
• Interchangeable blocks and rails for flexible assembly
• Corrosion-resistant surface treatments for long-term durability

Applications

Linear ball guides are widely used in:

• CNC machine tools and machining centers
• Automation equipment and assembly lines
• Industrial robots and pick-and-place machines
• 3D printers and optical instruments
• Semiconductor and inspection equipment

Their high precision and low maintenance make them an essential part of modern motion systems.
