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.Each row of balls is placed at a contact angle of 45° so that the rated loads applied to the LM block are uniform in the four directions (radial, reverse radial and lateral directions), enabling the LM Guide to be used in all orientations.The high temperature type LM Guide 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.

Dimensional Stability Data

Since this model has been treated for dimensional stability, its dimensional change after being cooled or heated is only minimal.

Note1) The above data on overall length and curvature indicate dimensional change when the LM rail is cooled to normal temperature after being heated at 150°C for 100 hours.
Note2) The samples consist of high temperature, standard and stainless steel types of model HSR25 + 580L.

Rolling Resistance Data in Relation to Grease

Use a high temperature grease with which the rolling resistance of the LM system little fluctuates even temperature changes from a normal to high range.

For the measurements above, model HSR25M1R1C1 is used.

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/°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. See Calculating the Modified Nominal Life for details.
