(1)在NSK轴承安装之前,应该用适当的测量工具按设计图纸上的技术要求规定,检查轴和座孔以及有关零件的加工质量(如尺寸精度、形状精度和表面粗糙度等)。
(1) prior to installation of NSK bearings, should use the appropriate measuring tool with the technical requirements on the design drawings, check the shaft and hole as well as the relevant parts of the processing quality (such as size, shape, precision and surface roughness, and so on).
(2)轴和座孔的装配表面上如有碰伤、毛刺、锈斑或固体微粒(如磨屑、砂粒、泥土)等存在,不仅会使轴承安装困难并使安装位置不正确,而且固体微粒如落入轴承内就会起研磨作用,当NSK轴承旋转时就会磨伤或擦伤NSK轴承的工作表面,所以在安装之前必须仔细加以检查,如发现有上述缺陷,应加以修正。例如利用油锉除去毛刺、凸起碰痕、锈斑,并用细砂布打光,又如清洗固体微粒、污物等。
(2) axis and block hole of Assembly surface Shang as has touch injury, and Burr, and rust or solid particles (as mill chip, and sand grain, and soil), exists, not only will makes bearing installed difficulties and makes installed location does not correct, and solid particles as hands bearing within on will since grinding role, dang NSK bearing rotating Shi on will mill injury or abrasions NSK bearing of work surface, so in installed zhiqian must carefully be check, as found has above defects, should be amendment. Such as the use of dead file remove the burrs, toe touch marks, rust and sand cloth illuminated, such as cleaning solid particles, dirt, etc.
(3)应将装配表面用洁净的汽油、煤油、甲苯或二甲苯等溶液清洗洁净,并用洁净的抹布擦干,再涂上薄薄一层润滑油,这样可使安装操作更方便。
(3) mounting surface should be clean gasoline, kerosene, such as toluene or xylene solution clean, wipe with a clean rag, and then spread a thin layer of lubricant, which can make the installation more convenient to operate.
(4)临安装时打开NSK轴承封装,将它浸入上述汽油等液体中以手轻缓地转动,要保证保持架,滚动体以及滚道表面的封装油彻底被清洗洁净。
(4) Provisional open NSK bearings when package is installed, to immerse it rotating liquids such as gasoline to hand in mitigation mentioned above, to ensure that cage, rolling elements and raceways encapsulates oil on the surface is thoroughly clean.
(5)清洗大量NSK轴承时,先用温度为90~100℃的热机油淋烫以使封装油熔化,同时用无锋口且不落屑的工具挖净全部旧油,再淋烫几分钟,然后用煤油冲洗去机油,最后再用汽油清洗一遍。清洗洁净后,应戴上薄膜手套将轴承放在工作台上的洁净的布上或纸上晾干。
(5) when you wash a lot of NSK bearings, 90~100℃ hot oil shower hot with temperature so that the encapsulated oil melted, while no ARRIS and don't exfoliation tool dig all the old oil, spraying hot for a few minutes, and then rinse it with kerosene oil, last used petrol to clean it again. After you clean, you should put on bearings are in the stage of film gloves dry on a clean cloth or paper.
(6)注意带密封NSK轴承不可用本法清洗,密封的内部应保持原样不可清洗。
 (6) note with sealed NSK bearings not used this law to clean, sealed inside should remain as it stood could not be cleaned.
