THK’s LM Guide HSR M1LC SERIES represents a specialized linear motion solution engineered for high-temperature environments where standard components would falter. As a full ball type LM Guide, it incorporates a recirculating ball bearing system within a robust carriage and rail assembly, ensuring smooth, precise linear motion under demanding thermal conditions. The series is constructed from heat-resistant materials, including specially treated steel and high-temperature grease, allowing continuous operation in ambient temperatures up to 150°C and peak resistance to 200°C. This thermal resilience is critical for applications involving process heat, friction-induced warmth, or proximity to heating elements.
Key technical features distinguish the HSR M1LC in performance and reliability. Its full ball contact design maximizes load distribution across all rolling elements, significantly enhancing rigidity and load capacity while minimizing deformation under stress. The guide incorporates a highly efficient sealing system with multi-layer contact seals and metal scrapers that prevent ingress of contaminants like dust, chips, or splashing liquids, even as material properties shift with temperature. Pre-loaded ball circuits eliminate internal clearance, delivering high positional accuracy and repeatability essential for precision tasks. Additionally, the optimized recirculation system reduces noise and vibration, contributing to smoother operation and extended service life by mitigating wear.
Performance advantages are evident in its operational stability and longevity. The high-temperature compatibility ensures consistent precision and minimal thermal expansion effects, maintaining alignment and reducing downtime for recalibration. Its high rigidity allows for higher loads and moments, supporting heavier components or more aggressive machining without sacrificing accuracy. The low-friction coefficient of the ball bearings translates to reduced drive power requirements, enhancing energy efficiency in continuous operations. Maintenance intervals are extended due to the durable construction and effective sealing, lowering total cost of ownership.
Typical applications span industries where heat and precision intersect. In industrial machinery, the HSR M1LC is deployed in injection molding machines for ejector mechanisms, die-casting equipment for linear actuation, and furnace door systems requiring reliable movement under radiant heat. Automotive manufacturing utilizes these guides in welding robots operating near high-temperature processes, engine assembly lines for positioning components, and brake testing equipment subjected to frictional heat. Within precision equipment, they are integral to semiconductor manufacturing tools like wafer handling robots, where cleanroom compatibility and thermal stability are paramount, and in packaging machinery for sealing stations that generate consistent heat. This versatility makes the series a cornerstone for advancing automation in challenging thermal environments.
