Linear guideways are a type of rolling guidance system where steel balls circulate infinitely between the slider and the rail, enabling the load platform to move along the rail with high-precision linear motion. Compared to traditional sliding guidance systems, rolling guidance reduces the coefficient of friction to 1/50 of that of sliding, significantly minimizing static friction differences. This eliminates slippage during operation, achieving μm-level positioning accuracy.
(1) High Positioning Accuracy
Linear guideways utilize rolling friction, reducing the coefficient of friction to 1/50 of sliding systems. The minimal difference between dynamic and static friction prevents slippage, ensuring μm-level positioning precision.
(2) Low Wear and Long-Term Precision Maintenance
Traditional sliding systems suffer from oil film inversion and insufficient lubrication, leading to wear and accuracy degradation. Rolling guidance minimizes wear, enabling prolonged precision retention.
(3) High-Speed Operation with Reduced Drive Power
The low friction of linear guideways allows smooth operation with minimal power input. Reciprocating motions further reduce energy consumption, and reduced heat generation supports high-speed applications.
(4) Multi-Directional Load Capacity
Specialized constraint structures enable simultaneous bearing of vertical, horizontal, and lateral loads, unlike sliding systems that struggle with lateral loads.
(5) Easy Assembly and Interchangeability
Alignment of mounting surfaces and torque-controlled fastening ensure repeatability. Unlike sliding systems requiring frequent scraping, linear guideways allow component replacement (slider, rail, or entire unit) to restore precision.
(6) Simplified Lubrication
Sliding systems require complex lubrication channels, while linear guideways integrate grease fittings for direct manual or automatic lubrication via hoses.
