Features
High-Temperature LM Guide
- The use of stainless steel in the endplates and high-temperature rubber in the end seals enables a maximum service temperature of 150°C.
- Since it is dimensionally stabilized, the product demonstrates superb dimensional stability after being heated or cooled (note that it shows linear expansion at high temperature).
- Since the LM block, LM rail, and balls use stainless steel, which is highly corrosionresistant,this product is optimal for clean room applications.
- This product uses high-temperature grease that shows little grease-based fluctuation in rolling resistance even if the temperature changes from normal to high levels.
LM Guide for Medium-to-Low Vacuums
- This LM Guide can be used in various environments ranging from atmospheric pressure to a vacuum (10-3[pa]).
- This product is capable of withstanding baking temperatures up to 200°C*.
* If the baking temperature exceeds 100°C, multiply the basic load rating by the temperature coefficient. - The use of a labyrinth end seal designed for medium-to-low vacuum increases grease retention and allows extended use in a vacuum.
- The use of a grease designed for medium-to-low vacuums enables stable rolling resistance.
Corrosion-Resistant LM Guide
- The LM rail uses the highly corrosion-resistant, austenitic stainless steel SUS304, and the LM block and balls are made of SUS431, the martensitic stainless steel with the highest corrosion resistance. This enables a drastic increase in corrosion resistance over conventional stainless steel (SUS440C).
