(2) Before the installation of NSK bearing, the machining quality of shaft, seat hole and relevant parts, such as dimensional accuracy, shape accuracy and surface roughness, should be checked with appropriate measuring tools according to the technical requirements on the design drawings.
(3) Before installation, open the NSK bearing package, immerse it in the above-mentioned gasoline and other liquid, and turn it gently by hand. Ensure that the seal oil on the cage, rolling element and raceway surface is thoroughly cleaned.
(4) The assembly surface shall be cleaned with clean gasoline, kerosene, toluene or xylene solution, dried with clean cloth, and then coated with a thin layer of lubricating oil, so as to make the installation and operation more convenient.
