Temperature range Since the linear motion system will be quenched to harden the surface, when the operating temperature exceeds 100°C, the hardness of the material will decrease, and the rated load will decrease (refer to the hardness coefficient). In addition, when resin is used in components, there is a problem with its strength, and it cannot be used at high temperatures. The following are representative models and recommended operating temperature ranges of linear motion systems. Component materials include resin parts made of steel and stainless steel Other operating temperature range -20°C to 80°C -20°C to 110°C -20°C to 140°C*-Rolling guide SEB-A/SEBS-BSGL/SGWSERSEBS-BMSERS-Ball spline SSP/SSPF/SSPB-SPLFS-Outer cylinder rotary ball spline SPR---sliding bushing SM G/KB G/SW G/SMS G/KBS G/SWS G/GMSMA G/AK GCE/CDSM/KB/ SWSMA/AKSMS/KBS/SWSSMSA/AKS-Top Bushing TK/TKATKE/TKD---Stroke Bushing-SR/SRB--Sliding Rotary Bushing RK/FR/FRASRE--Cross Roller Guide NVSV/RVSVS-Sliding Taiwan NVTSVT/SYTSYTSSVTS** miniature slide rail--SYBS-sliding screw-SS--if it is made of stainless steel and has a seal, please use it below 120°C. If it is used outside of normal temperature, it needs to be discussed and confirmed in advance. In this case, please contact NB directly for consultation. If foreign matter or garbage is mixed in the use environment, it will have a negative impact on the motion performance of the linear motion system, and it will also lead to abnormal wear and tear of the product in advance. If it is used under normal conditions, the sealed linear motion system can basically prevent it, but if it is used in an extremely poor environment, as shown in the right figure, a dust cover or a protective cover must be installed separately and other components in order to protect the linear motion system.
