Each bearing models have different characteristics according to the design, which makes the applicability of various models for a particular purpose, more or less will be a little different. For example, the deep groove ball bearings can withstand moderate radial and axial loads. They are low friction, high accuracy can be manufactured to meet different types of quiet operation requirements. So they are more suitable for small and medium-sized electric motor.
Spherical roller bearings can withstand very high loads and can automatically aligning. Such characteristics make them very suitable for use in such as heavy engineering, such works have heavy-duty shaft deflection and misalignment.
But in many cases, in the choice of Bearings, since the need to consider a variety of factors, balanced between the severity of the pros and cons, so there are no rules.
The information provided here should be able to prompt the choice of bearing the standard model, which are the most important factors that should be considered in order to make the right choice.
- Free space
- Load
- Misalignment
- Accuracy
- Speed
- Quiet operation
- Stiffness
- Axial displacement
- Installation and Removal
- With seals
The standard model of the bearing in the table can be found in a comprehensive overview of about them design characteristics and suitability for a particular purpose of information.
For details of the individual bearing models, including the product features and design specifications have the individual bearing models, see Introduction. Not included in the table bearing models, usually only suitable for a small number of specific purposes.
The form is a plain bearing Model classification. The symbol is limited, and therefore can not make a precise distinction, and some features are not only decided by the bearing design. Contain, for example, angular contact ball bearings or tapered roller bearings configuration, its rigidity depends on the pre-load and the running speed, and the speed of operation by the precision of the bearing and its associated components and to maintain the frame design. Despite its limitations, but based on the form, or can choose to go to a suitable bearing models. Must also be noted that the total cost and inventory of the entire bearing configuration considerations also affect the final choice.
In the design of bearing arrangements, there are other important criteria need to comply with this carrying capacity and life, friction, the allowable speed range, bearing internal cleaning or pre-load, lubrication and sealing. These standards in separate chapters detailed description in the catalog.
