Lubrication has the following purposes: to reduce the friction between the rolling elements or between the rolling elements and the track surface, prevent sintering, reduce the wear of components, and at the same time, it can also generate an oil film on the surface of the components to prevent rust, etc. . In order to fully utilize the performance of the linear motion system, it is necessary to determine the lubrication method suitable for the conditions of use and select the most appropriate lubricant. Lubrication methods include oil lubrication and grease lubrication. Turbine oil ISO specification VG32-68 is recommended for oil lubrication, and lithium soap base grease No. 2 is recommended for grease lubrication. Sliding bushes, etc. are only coated with anti-rust oil that has little influence on the lubricant. Please use after applying lubricant. (Refer to Table 1-37) In addition, parts with track grooves such as rolling guides can be used as they are because they are filled with grease. In the future, please supplement in time according to the conditions of use and the environment. Under normal usage conditions, the recommended refueling interval is about 6 months or 1,000km. NB has prepared the following greases, please select and use according to the operating conditions. KGL grease (low dust generation grease) KGL grease is an extremely excellent grease with low dust generation using a lithium-based thickener, suitable for use in clean rooms. KGU Grease (Low Dust Generation Grease) KGU Grease is a grease that uses a urea-based thickener. It is characterized by not only excellent low dust generation, but also very low dynamic friction resistance at low speeds. Item Grease Name KGL Grease KGU Grease Appearance Yellowish White Light Brown Base Oil Synthetic Oil/Refined Mineral Oil Mixed Synthetic Oil/Refined Mineral Oil Mixed Base Oil Kinematic Viscosity (mm/s 40°C) 32 About 85 Thickener Lithium After mixing soap and urea, the viscosity is 237246 Dropping point (°C) 201250 or above Copper plate corrosion (100°C, 24hrs) Qualified Evaporation (mass%) 0.8 (99'22h) 0.61 (150'22h) Oil separation (mass% 100 ℃, 24hrs) 0.90.1 Oxidation stability (MPa 99℃, 100hrs) 0.040.015 Bearing rust prevention (52℃, 48hrs) Qualified Qualified Operating temperature range (℃) -20~120-20~150グリース关にする Various data 、こちらのPDFをごRefer to ください. Precautions during operation and use NB linear motion system is a precision component, in order to ensure its accuracy and enable you to use it safely, please pay attention to the following items. Handling Precautions If the linear motion system is dropped or given a strong impact by hitting it with a hammer, etc., it may cause indentations on the track surface, affecting the smoothness of movement and affecting the life. In addition, resin parts may be damaged, so please be careful. If you disassemble each part without authorization, dust, etc. may enter the inside, which may deteriorate the assembly accuracy, so please do not disassemble the parts. Sometimes just tilting the rail or shaft can make the slider or outer cylinder slide, so be careful not to remove the rail or shaft by mistake. In order to fully utilize the performance of the linear motion system, the accuracy of the mounting surface and the parallelism of the installed axis are very important factors. Therefore, ensure sufficient mounting accuracy. Precautions for use Please try to avoid dust and foreign matter from entering during use. If dust, coolant, etc. are scattered in the operating environment, please use a dust cover or a protective cover to protect it. Fix the rails of the NB linear motion system to the roof, and when the slider or outer cylinder is used under load, if the slider or outer cylinder is damaged, it may fall off the rail, so please install safety devices, etc., and implement Additional measures to prevent falling. Relevant points for life study When the load acting on a slider or outer cylinder exceeds 0.5 times the basic dynamic load rating (P>0.5C), the actual life may be shorter than the life calculation value, so it is recommended to use it below 0.5C. When rolling elements such as steel balls and cylindrical rollers perform repeated motions with a small stroke of less than half a revolution, early wear called fretting wear occurs at the contact part between the rolling elements and the raceway surface. Although there is no perfect countermeasure, the life can be extended by using anti-fretting grease or by performing a movement of approximately the entire stroke of the slider or the outer cylinder every thousands of times. NB has prepared anti-fretting grease, please use it when a slight stroke occurs.
