Nippon Bearing products recommended temperature range
No. 170E-1 main catalogue page Eng-5. and Eng-38.
The NB linear systems are heat-treated in order to harden the surface. Therefore, if the temperature of the liner system exceeds 100 °C, the hardness and load rating will be reduced (refer to pages Eng-5. hardness coefficient). If resin is used in any one of the components, the system cannot be used in ahight-temperature environment. The recommended operating temperature ranges for each type of linear system are listed in below downloadable brochure.
