The THK LM Stroke Miniature Stroke Model MST SERIES represents a compact, high-precision linear motion solution engineered for applications demanding minimal space utilization without compromising on performance or reliability. Characterized by its ultra-slim design and lightweight construction, this series integrates a miniature stroke cylinder with a guided mechanism, delivering smooth, accurate linear movements in constrained environments. The MST SERIES employs a unique ball screw or lead screw drive system, encapsulated within a rigid aluminum alloy housing that ensures structural integrity while minimizing overall mass. Key technical features include a self-lubricating bushing system for maintenance-free operation, corrosion-resistant stainless steel shafts, and precision-ground components that guarantee consistent stroke accuracy and repeatability. With stroke lengths tailored to specific needs—typically ranging from 10mm to 100mm—the series supports dynamic load capacities up to 50N and offers optional configurations for custom mounting, sealing, and feedback integration.

Performance advantages of the MST SERIES stem from its optimized design for low friction and high efficiency. The incorporation of THK’s proprietary Caged Ball technology reduces noise and vibration during operation, extending service life even under high-cycle conditions. Its compact footprint allows for seamless integration into multi-axis systems, while the guided mechanism prevents rotational movement, ensuring straight-line accuracy with deviations of less than 0.01mm per 100mm of travel. The series operates efficiently across a temperature range of -10°C to 60°C and is compatible with various lubricants, enhancing adaptability to harsh industrial environments. Additionally, the MST SERIES boasts rapid response times and low power consumption, making it ideal for energy-sensitive applications. These attributes contribute to reduced downtime, lower total cost of ownership, and enhanced system throughput.

In industrial machinery, the MST SERIES excels in precision assembly robots, pick-and-place units, and semiconductor manufacturing equipment, where its miniature size and accuracy facilitate delicate component handling and positioning. For automotive systems, it is deployed in fuel injection testing apparatus, transmission control modules, and sensor calibration devices, leveraging its durability and repeatability to meet stringent automotive standards. In precision equipment, such as medical diagnostic instruments, optical alignment systems, and laboratory automation, the series provides reliable linear motion for tasks requiring micron-level precision and contamination-free operation. By combining compactness with robust performance, the THK MST SERIES addresses the evolving demands of modern automation, offering a versatile solution for applications where space, weight, and accuracy are critical factors.
