Features
Structure and Features
Balls roll in four rows of raceways precision-ground on an LM rail and an LM block, and endplates incorporated in the LM block allow the balls to circulate. Since it is a compactly designed model that has a low sectional height and a ball contact structure rigid in the radial direction, this model is optimal for horizontal guide units. High temperature type LM Guide model SR-M1 is capable of being used at service temperature 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 endplates and high temperature rubber in the end seals achieves the maximum service temperature of 150°C.
Dimensional Stability
Since it is dimensionally stabilized, it demonstrates superb dimensional stability after being heated or cooled (note that it shows linear expansion at high temperature).
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 low 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)
- Averagecoeffi cient of linear expansion: 11.8×10-6/°C
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. SeeCalculating the Modified Nominal Lifefor details.
