Linear Guide

Our Linear Guides are high-precision motion components designed to provide smooth, stable, and accurate linear movement across a wide range of industrial applications. Manufactured using advanced materials such as high-carbon alloy steel or stainless steel and treated with precision grinding and heat-hardening techniques, our linear guides offer exceptional rigidity, load capacity, and wear resistance. The combination of linear guide rails and rolling elements (usually recirculating ball bearings or rollers) enables low-friction operation, ensuring high efficiency and minimal power loss during movement. Compared to traditional sliding systems, linear guides reduce friction by up to 90%, resulting in smoother motion, lower energy consumption, and less wear on mechanical components. Our linear guides feature high positioning accuracy and excellent repeatability, which are essential for applications such as CNC machines, 3D printers, robotics, semiconductor equipment, medical devices, and high-speed automation lines. Thanks to their ability to carry both radial and lateral loads simultaneously, they maintain consistent performance under complex dynamic conditions. The design incorporates self-aligning capabilities to absorb mounting errors and reduce assembly complexity. Optional dustproof seals and lubrication systems ensure long-term operation in harsh or dusty environments, significantly extending service life and reducing maintenance costs. Our linear guides are available in various sizes, preload levels, accuracy grades, and block types (flange, square, or miniature), offering full customization to meet specific design and installation requirements. Whether the demand is for high speed, heavy load, corrosion resistance, or silent performance, we provide the right linear guide solution tailored to your application. Additionally, our products meet international standards and can be easily integrated into existing systems. With consistent quality, fast delivery, and technical support, our linear guides offer the reliability, precision, and efficiency that modern industries demand. Choose our linear guide systems to enhance your equipment’s motion control performance, improve operational accuracy, and increase overall productivity.

Durable and Low-Friction Linear Rails for High-Speed Equipment

 

A linear guide, also known as a linear motion guide or linear rail, is a mechanical component designed to support and guide motion in a straight line with high precision and low friction. It consists of a rail and a carriage (or block) that moves along the rail with the help of recirculating ball or roller bearings. Linear guides are widely used in CNC machines, 3D printers, automation systems, packaging machinery, and other industrial equipment where precise and smooth linear motion is essential.

Compared to traditional slide systems, linear guides offer significantly higher load capacities, stiffness, and accuracy. Their rolling contact reduces friction to a minimum, resulting in higher speed capability and longer service life. Linear guides can support loads in both horizontal and vertical directions and maintain stable performance even under high acceleration and deceleration.

Linear guides are available in various sizes, preload levels, and accuracy grades to suit different application requirements. Common types include ball-type linear guides, roller-type guides, and miniature linear guides. Materials typically include hardened alloy steel or stainless steel with precision grinding for enhanced durability and corrosion resistance.

Thanks to their modular design, linear guides are easy to install, align, and maintain. Many models also support self-lubrication and come with dust-proof seals for extended maintenance-free operation.

Whether in robotics, machine tools, semiconductor equipment, or medical devices, linear guides deliver the precision, efficiency, and reliability that modern automation demands.

リニアガイドの選択、設置、メンテナンスガイド

  • リニアガイドにはどんな種類がありますか?適切なモデルを選ぶには?

    一般的なリニアガイドの種類には、ボールタイプ、ローラータイプ、ワイドレールタイプなどがあります。選定にあたっては、荷重、精度、速度、使用環境、設置方法などの要素を考慮する必要があります。様々な産業用途に適したモデルがあります。例えば、高剛性が求められる場合はローラータイプ、高速が求められる場合はボールタイプが適しています。

  • リニアガイドの精度グレードとは?アプリケーションにどのような影響を与えますか?

    一般的な精度等級には、普通等級(N)、高精度等級(H)、精密等級(P)などがあります。精度が高いほど、位置決め精度が高くなります。CNC工作機械や半導体装置など、繰り返し精度に対する要求が高い装置に適しています。

  • リニアガイドを正しく取り付けるには?注意すべき点は何ですか?

    取り付け前に、ガイドレールベースが水平であることを確認してください。これにより、ズレが生じません。専用の取り付け工具を使用して、スライダーとガイドレールを固定し、同軸度と平行度を確保してください。取り付け後は、走行試験を実施し、ズレがないことを確認してください。

  • リニアガイドのメンテナンス方法は?潤滑サイクルはどのくらいの頻度ですか?

    ガイドレール表面の埃は定期的に清掃し、スライダー内部の転動部品には専用の潤滑グリースを塗布する必要があります。500時間ごと、または使用環境に応じて給油することをお勧めします。過酷な環境では、メンテナンスサイクルを適切に短縮する必要があります。

  • リニアガイドの使用中に異常なノイズや遅れが発生した場合はどうすればよいですか?

    原因としては、潤滑不足、ガイドレールの不適切な取り付け、スライダー内部への異物の侵入などが考えられます。機械を直ちに停止し、点検、清掃、再給油、必要に応じてスライダーアセンブリの調整または交換を実施してください。
