SKF bearing installation and maintenance

Bearing installation is correct, a direct impact on accuracy, longevity, performance. Therefore, the design and installation of the bearing assembly department to be adequately studied. I hope to be in accordance with the operating standards for installation. The projects are usually operating standards are as follows:
(1), cleaning SKF bearings and associated components
(2), check the associated component size and finishing conditions
(3), the installation
(4), installed after checking the bearing
(5), the supply of lubricant
I hope in the upcoming installation, just open the SKF bearings packaging. General grease lubrication, without cleaning, direct filling grease. Lubricating oil, do not have general cleaning, but the equipment used or high-speed bearings, etc., use a fresh oil washed to remove rust coating agent on the bearing. Removes rust bearings, rust, so you can not put aside. Moreover, the sealed bearing grease, used directly without cleaning.
When mounted to the housing, generally with more clearance, the amount of interference with the outer ring, usually pressed into the press, or is installed after the cooling method of shrink fit. With dry ice as coolant, shrink with the installation, the moisture in the air condenses on the surface of Japanese bearings. Therefore, the need for appropriate corrosion protection.
SKF Bearings Cleaning: Remove lower bearing overhaul, the first recorded appearance of the bearing to confirm remaining amount of lubricant, the lubricant used after sampling inspection, wash bearings. As a cleaning agent, general use gasoline, kerosene.
Sperm washing is to clean the oil bearing side of the rotating, while carefully cleaned. In addition, cleaning the oil must be kept clean.
SKF bearing maintenance and judgment: In order to determine whether the removed bearing can be used to clean the bearing after inspection. Check the raceway, the raceway, with the surface state, cage wear, bearing clearance increases and there is nothing to fall dimensional accuracy injury exception. Non-separable type of small ball bearings, the inner ring with one hand the level of support, rotating outer ring to confirm whether smoothly.
