NSK bearings installation effect on the bearing life

NSK bearings for proper installation, affects the precision, life and performance. Therefore, the design and assembly department for NSK bearings installed to fully research. Hope to work in accordance with the standards for installation. Operation standard project usually is as follows: ( 1) Check the size of the associated components and finish machining condition; ( 2) Installation; ( 3) Supply of lubricant. ( 4) NSK bearing NSK bearings and related parts cleaning; ( 5) NSK bearings installed after check; Hope before the installation, NSK bearings before open the packaging. Lubricating oil, ordinary also don't have to be clean, but the instrument with or high speed with NSK bearings, etc. , to be washed with clean oil, remove rust inhibitor) on the NSK bearings. General grease lubrication, cleaning, not directly fill grease. Furthermore, NSK bearings has grease sealed, not directly use cleaning. NSK bearings to remove the rust inhibitor, is easy to rust, so can't place. When installed on the shell, clearance fit more commonly, outer ring have surplus quantity, usually use the pressure into the press and or have shrink fit method of cooling after installation. Use dry ice as coolant, shrink fit installation, the moisture in the air condenses on the surface of NSK bearings. So, need a good rust prevention measures. NSK bearing NSK bearing installation method, structure, cooperate, conditions vary, in general, as more as the axis of rotation, so the inner circle need interference fit. Taper hole, installed directly on the taper shaft, or use the socket installation. NSK bearings cylindrical hole, multi-purpose press pressure into, or multi-purpose hot charging method.
