The installation of INA bearings

Whether the installation of INA bearings is correct or not, that directly do effect on the accuracy, use-life and performance of bearings. Therefore, it’s necessary that the design and assembly departments should put adequately studied on the installation of INA bearings. Please install INA bearings in accordance with the operating standards:
（1）、Cleaning INA bearings and the relevant components.
（2）、Checking the size and finish machining situation of the relevant components.
（3）、Installation.
（4）、the inspection after installation of INA bearings.
（5）、Supplying the lubricant.
Before the intallation of INA bearing, the first step is to open the packing. Generally if it is lubricated with lubricating grease, we filled with grease directly without cleaning first. If it is lubricated with lubricating oil, the most don’t need to wash at first. However, if INA bearings are used in the equipment or high-speed, we should wash them with clean oil to remove the antirust on INA bearings. Because INA bearings without antirust easily to get rusty, we should not put them in the air. If INAearings were enclosed lubricating grease, we chould use them directly without washing.
According to the strucure, coordination and condition, the installation of INA bearings are different. Usually, the most INA bearings are rotation of axes, so inner rings need pinch fit. To install Cylindrical Roller Bearings, we usually use press machine to jam them in or use hot charging method. Different from this, we directly installed Tapered Roller Bearings in the taper axis or the installation sleeve.
When we install the shell of INA bearing, because of much windage and pinch fit outer rings, we should use press machine to jam them in or intall them after cooling shrinkage. In the occasion of the installation with cooling shrinkage, if we use carbon ice for refrigerant, moisture in the air will be condensed in the bearing surface. Due to it, appropriate anti-corrosion measures are necessary.
