Rolling bearing type selection-08

form factor restrictions

Once the final value for the required load rating has been determined, you must consider the external dimensions required for bearing mounting, including the mounting and mounting of the bearings considered here. and the size of the shaft to match the bearing with the required load rating. These factors help determine bearing construction and size and can also exclude certain bearing types. In some cases, space constraints preclude selection even before the load rating is determined.

For example, if the bearing profile is very narrow, ball bearings are the only type that will work here. Alternatively, if a very small diameter bearing housing must be used, you will need to install two or more roller bearings on the same shaft to achieve adequate load ratings.

Another common contradiction arises when the size of the shaft differs significantly from the required bearing load rating. If the shaft is large but the load is light, even if the required rated load is small, an expensive, large bearing with a high rated load will have to be proposed. In this case, it is best to contact the bearing manufacturer in order to propose the most cost-effective one. Solution.
