THK’s LM Guide LM Guide (full ball type) High Temperature SR M1V SERIES represents a specialized advancement in linear motion technology, engineered to deliver exceptional performance and reliability in demanding high-temperature environments. This series incorporates a full ball-type design where recirculating balls maintain continuous contact between the rail and block, ensuring smooth, precise linear movement even under extreme thermal conditions. The SR M1V is constructed from heat-resistant materials, including specially treated steel components and high-temperature lubricants, allowing it to operate reliably at temperatures up to 150°C. Its robust sealing system effectively prevents the ingress of contaminants like dust, chips, and moisture, while retaining lubrication to extend service life in harsh industrial settings.

Key technical features of the SR M1V SERIES include its optimized ball groove geometry, which minimizes friction and distributes loads evenly across the rolling elements. This design enhances rigidity and load capacity, supporting high moment loads and dynamic forces without compromising accuracy. The guide incorporates a compact, low-profile structure, making it suitable for applications with space constraints. Preloaded ball configurations are available to eliminate backlash, ensuring precise positioning and repeatability. Additionally, the series offers corrosion-resistant options, further broadening its applicability in aggressive environments.

Performance advantages are evident in its ability to maintain smooth motion and high positional accuracy under thermal stress, reducing wear and maintenance requirements. The full ball-type recirculation system provides high-speed capability and low noise operation, contributing to energy efficiency and improved machine productivity. Its durability in high-temperature conditions translates to longer intervals between replacements and reduced downtime, offering significant cost savings over the system’s lifecycle.

Typical applications for the SR M1V SERIES span various industries where high temperatures and precision are critical. In industrial machinery, it is used in injection molding machines, die-casting equipment, and furnace door mechanisms, where thermal resistance ensures consistent operation. Automotive systems benefit from its integration into engine testing rigs, welding robots, and paint shop conveyors, where it withstands heat from processes and ambient conditions. Precision equipment applications include semiconductor manufacturing tools, LCD panel handlers, and medical device assemblers, where its accuracy and thermal stability support fine-tuned processes. By combining high-temperature resilience with THK’s renowned precision, the SR M1V SERIES enables enhanced performance and reliability in the most challenging operational scenarios.
