Features

Structure and Features

Balls roll in two 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. 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 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) ● 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. SeeCalculating the Modified Nominal Lifefor details.
