2 Structure and eatures 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. High temperature type miniature LM Guide model is capable of being used at service temperature up to 15 thanks to THK s unique technologies in material, heat treatment and lubrication. Maximum Service Temperature: 15 Use of stainless steel in the endplates and high temperature rubber in the end seals achieves the maximum service temperature of 15. LM Guide 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 fl uctuation in rolling resistance even if temperature changes from low to high levels. Thermal Characteristics of LM Rail and LM Block Materials Specifi c heat capacity:.481 J/(g K) Thermal conductivity: 2.67 W/(m K) Average coefficient of linear expansion: /

3 Types and eatures Models, K, M1V This model is a standard type. Specification Table Model N It has a longer overall LM block length (L) and a greater rated load than standard types. Specification Table Models W, M1WV These models have greater overall LM block lengths (L), broader widths (W) and greater rated loads and permissible moments than standard types. Specification Table Model WN It has a longer overall LM block length (L), a greater rated load than standard types. Achieves the greatest load capacity among the high temperature type miniature LM Guide models. Specification Table

4 Service Life When using this product in temperatures higher than 1 C, always multiply the basic dynamic load rating by the temperature coefficient when calculating the rated service life. See A for details. LM Guide

Contact THK for details Prevention of LM block from falling off of LM rail In models /W, the balls fall out if the LM block comes off the LM rail. or this reason, LM Guide assemblies are delivered with a part which prevents the LM block from coming off the rail. If you remove this part when using the product, please take precautions to avoid overrunning the blocks off of the rail.
