NSK Bearings installed to carry out the operation to check is to check the installation is correct. However, NSK Bearings operate in different types of mechanical inspection methods, such as small machines and large-scale machinery.
1, small mechanical check of the operation of the NSK Bearings
Small mechanical hand rotation to confirm whether the rotation is smooth. Include examinations of dysfunctional due to foreign objects, scars, indentation; rotation torque generated by the uneven due to poor installation, mount processing bad; by the clearance is too small, the installation error seal friction caused torque . If there is no exception, you can start the power operation.
2, check the operation of large machinery NSK Bearings
Large machinery can not be manually rotate, therefore, turn off the power immediately after the start of the no-load inertia operation, check for vibration, sound, and rotating parts in contact, and so to enter the dynamic, sure no abnormal operation. Power operation from no load low speed, slowly increased to the set condition rated operation. Commissioning in inspection matters as whether there is abnormal noise, the transfer of the NSK bearing temperature, lubricant leakage and discoloration. If anything unusual in the commissioning, should be immediately discontinued operation, check the mechanical, it is necessary to remove the bearing check.
