Temperature Range

The NB linear systems are heat-treated in order to harden the surface. Therefore, if the temperature of the linear system exceeds 100℃, the hardness and load rating will be reduced (refer to page Life, hardness coefficient). If resin is used in any one of the components, the system cannot be used in a high-temperature environment. The recommended operating temperature ranges for each type of linear system are listed in the table below.

* If the system is made of stainless steel and has a seal, the temperature range is up to 120℃

** Please contact NB if the system is to be used out of room temperatures.

Operating Environment

Operating EnvironmentForeign particles or dust in the linear system affects the motion accuracy and shortens the life time. Standard seals will perform well for dust prevention under normal operating conditions, however, in a harsh environment it is necessary to attach bellows or protective covers as the right figure shows.
