Structure and Features

Features
- Operable in various environments at pressure between atmospheric pressure and vacuum (10 -3 [Pa]).
- Capable of withstanding baking temperature up to 200°C *
- Use of a newly developed labyrinth end seal dedicated for Medium-to-Low Vacuum increases grease retention and allows extended use in vacuum.
- Use of grease designed for Medium-to-Low Vacuum achieves a stable rolling resistance.
* If the baking temperature exceeds 100°C, multiply the basic load rating with the temperature coefficient.
Structure of the labyrinth end seal dedicated for Mediumto-Low Vacuum
The labyrinth end seal dedicated for Medium-to-Low Vacuum forms a multi-stage space as shown in the figure on the right to minimize the pressure difference between adjacent stages. This reduces the out-flow velocity of the oil inside the LM block to a minimum. In addition, the seal will not affect the rolling resistance since it does not contact the LM rail.

Achievable vacuum level
The LM Guide for Medium-to-Low Vacuum demonstrates an excellent achievable vacuum level.

Rolling resistance
The grease used in the LM Guide for Medium-to-Low Vacuum has a smaller rolling resistance than conventional fluorine grease and ensures stable rolling motion.

Precautions on Design
If a large moment is applied to a system consisting of one LM rail or one LM block per shaft, the labyrinth end seal may contact the LM rail, which could affect the system’s motion. If a moment is applied, it is recommended to use two rails with two LM blocks per rail. Contact THK for details.
