The THK LMIH SERIES flanged type Cut Flange Model LMIH linear bushings represent a specialized evolution in the Ball Bushing Linear Bushing family, engineered for high-load capacity and exceptional rigidity in compact linear motion systems. Featuring a unique cut-flange design, these units provide versatile mounting options, allowing for secure fixation from the top or side, which simplifies installation and enhances design flexibility in space-constrained applications. The construction incorporates a precision-engineered outer sleeve with a cutout section on the flange, maintaining the structural integrity necessary for demanding operational environments.

Key technical features include the utilization of high-grade chromium steel for both the outer ring and precision-ground balls, ensuring durability and long service life. The balls are arranged in a optimized recirculation system with a reinforced resin retainer, which minimizes friction, reduces noise, and prevents ball-to-ball contact, thereby extending component lifespan. The flanged design inherently provides high moment load resistance, making these bushings suitable for applications subject to tilting or overturning forces. Additionally, the inclusion of seals or shields at both ends effectively excludes contaminants such as dust and chips while retaining grease lubrication, which is critical for maintaining performance in harsh industrial settings.

Performance advantages of the LMIH SERIES are substantial, offering smooth, low-friction linear motion with high positional accuracy and repeatability. The compact flange design allows for direct mounting onto machine frames, reducing the need for additional support structures and saving valuable space. This series excels in handling both radial and moment loads efficiently, contributing to stable operation under varying dynamic conditions. The low maintenance requirements, coupled with the ability to operate at high speeds with minimal wear, result in reduced downtime and lower total cost of ownership for end-users.

Typical applications span across multiple high-performance sectors. In industrial machinery, these linear bushings are integral to automated assembly lines, precision machining centers, and material handling equipment where reliable linear guidance is paramount. Within automotive systems, they are employed in robotic welding arms, engine component testing fixtures, and transmission assembly jigs, benefiting from their robustness and precision. In the realm of precision equipment, the LMIH SERIES finds use in semiconductor manufacturing apparatus, medical device positioning systems, and optical instrument stages, where minimal vibration and high accuracy are critical. Their versatility and reliability make them a preferred choice for engineers seeking to enhance the performance and longevity of linear motion systems across diverse industries.
