In addition to bearing, the Bearing system also includes a shaft and seat. The importance of lubrication and sealing is also uncontrollable. A defective one-bore function depends on the existence of a proper lubricant, which, in addition to working fluid, also prevents corrosion of the burring and the penetration of foreign contaminating particles.
Cleaning the operating environment is a major factor in Bearing's life.
In order to design the layout of roller bearings,
• Pick the right bearings and
• The dimensions of the bearings are also determined,
But this is not the end. The other aspects of the issue should also be examined:
• Proper design and design of other layout components,
• Required Fit (Fit), Internal Clearance, Preload,
• Holding Devices,
• Necessary gaskets
• The type and amount of fluids,
• How to install and remove and so on.
Each of the above is effective in the function, reliability, and cost of layout.
The amount of work required depends on whether the previous experience with the same arrangement is available. When there is no previous experience, there is an unusual situation or the cost of the lay-out and related issues are of particular importance, and the amount of work required is increased. For example, more detailed calculations or tests are required.
As an advance, SKF produces a variety of bearings ups in the bearing industry in a series of up and running designs. In the next section of the MySQL, the layout designers will be able to find the necessary information in the order they need. Obviously, it's not possible to provide full coverage of all the details of the various applications.
The information provided in this section is relevant to the overall bearings, or at least a group of them, and specific information relating to any type of bearings in the relevant section is provided.
Note that information on load ratings, nominal speed, and fatigue load limits are highly rounded in the tables.
In order to better understand the common terms of bearings, these terms are described with help. The full details of the terms and definitions of Birling can be found in ISO 5593: 1997, "Rolling Bearings Vocabulary".
