Features
Structure and Features
Balls roll in two rows of raceways precision-ground on an LM rail and an LM block, and end plates incorporated in the LM block allow the balls to circulate. The high-temperature type miniature LM Guide Model RSR-M1 is capable of being used at service temperatures up to 150°C thanks to THK’s unique technologies in material, heat treatment, and lubrication.
Maximum Service Temperature: 150°C
Use of stainless steel in the end plates and high temperature rubber in the end seals achieves the maximum service temperature of 150°C.
Dimensional Stability
The product has undergone processing which grants it superb dimensional stability even when heated or cooled (though it does expand some at high temperatures).
Highly Corrosion Resistant
Since the LM block, LM rail, and balls use stainless steel, which is highly corrosion resistant, this model is optimal for clean room applications.
High-Temperature Grease
This model uses high-temperature grease that shows little grease-based fluctuation in rolling resistance even if temperature changes from normal to high levels.
Thermal Characteristics of LM Rail and LM Block Materials
● Specific heat capacity: 0.481 J/(g･K) ● Thermal conductivity: 20.67 W/(m･K) ● Average coefficient of linear expansion: 11.8 × 10-6/℃
Service Life
When using this product in temperatures higher than 100°C, always multiply the basic dynamic load rating by the temperature coefficient when calculating the rated service life. See Calculating the Modified Nominal Life for details.
