RSR-M1WN SERIES

THK’s LM Guide RSR M1WN SERIES represents a specialized linear motion solution engineered for high-temperature environments where standard components would fail. This full ball type LM Guide incorporates unique material selections and design innovations to maintain precision, load capacity, and longevity under continuous operating temperatures up to 150°C. The system features a stainless steel retainer and specially formulated heat-resistant engineering plastics that prevent deformation, seizure, or lubrication breakdown when exposed to sustained thermal stress. Races and balls are manufactured from through-hardened stainless steel, providing inherent corrosion resistance while retaining mechanical properties at elevated temperatures. A optimized sealing system combines metal and rubber seals to exclude contaminants like dust, chips, or fumes commonly found in industrial heating processes, while containing the high-temperature grease lubrication essential for smooth operation.

Performance advantages begin with maintained accuracy under thermal expansion, critical for precision positioning tasks in heated environments. The full ball contact design distributes loads evenly across four bearing points, delivering higher rigidity and stability than simplified linear guides. This configuration allows the RSR M1WN to handle moment loads effectively while providing smooth, low-friction motion with consistent precision over extended service life. The heat-resistant components prevent galling and retain proper preload, eliminating play that would compromise positioning accuracy. These guides exhibit minimal maintenance requirements despite harsh conditions, with lubrication intervals extended through specialized high-temperature greases.

Typical applications span industries where heat is inherent to the manufacturing process. In industrial machinery, these guides are deployed in semiconductor manufacturing equipment for wafer handling in high-temperature chambers, glass tempering lines where carriers move through heating and cooling zones, and plastic injection molding machines for ejector mechanisms operating near molten material. Automotive manufacturing utilizes these guides in painting line ovens where carriage systems transport components through curing cycles, and in engine test stands with heated environmental simulations. Precision equipment applications include laboratory automation in environmental testing chambers, food processing packaging machinery with steam sterilization requirements, and medical device sterilization systems where components must maintain accuracy through repeated high-temperature cycles. The RSR M1WN SERIES enables reliable linear motion where thermal challenges would compromise conventional guide systems, ensuring precision and durability in the most demanding heated applications.
