High temperature linear guides handle 150C

THK is launching a new range of High Temperature LM Guides, specified 'M1', for applications that involve exposure to extreme heat.

The new series of LM Guides are designed to operate at temperatures of up to 150C and feature stainless steel endplates and special purpose rubber seals, which resist high temperatures and remain fluid in motion.

The thermal characteristics of LM Rail and Block materials are 0.481 J/(g-K) specific heat capacity and 20.67 W/(m-K) Thermal conductivity, which can cope with difficult temperatures.

The High Temperature Guides are treated to minimise changes in dimension due to heating and cooling.

Another important feature of the new series is that the Linear Motion Guide is corrosion resistant and entirely made of stainless steel.

The lubricant used in the guide is fluorine based high temperature grease, and is sealed against external temperatures.

THK, aware of the fact that mixing other greases and lubricating oils can degrade performance, has chosen this lubricant as being the most compatible with LM Guide systems.

The end seals used in the new Linear Guides are rubber based, however, in the high-temperature 'M1' LM Guide a temperature resistant rubber is used for the seals to make them durable in hot and hostile environments.

The range of High Temperature Resistant LM Guides includes the SR-M1 high rigidity radial types, HSR-M1 four way equal load types, and RSR-M1 and RSR-M1W miniature types, in standard, wide rail and high capacity 'N' type.
