How to choose the size of the bearing
The load-carrying capacity and wear characteristics of Viiplus oilless bushing depend on the specific conditions of the specific application. Therefore, any calculation formula can only provide an approximation. To determine the required size of bushings, washers or strips, load-carrying capacity, service life requirements, operational reliability and a specific set of operating conditions (eg load, sliding speed) needs to be taken into account.
Various bushings available
Oilless Bushings are suitable for rotating, reciprocating, and linear motion, while straight (cylindrical) bushings can only carry radial loads, and flanged bushings can carry radial and axial loads in one direction.
Each bushing design and the combination has unique properties that make it suitable for certain specific applications.
What Other Bearing Specifications Are Important?
While the bearing tolerance classes primarily control boundary dimensions of the rings, it should also be noted that there are features that are critical to the bearing’s performance and life that are not controlled. These include internal clearance, surface finish, ball accuracy, torque, noise, cage type, and lubrication. These items should be specified along with the precision class when selecting bearings to ensure optimum life and performance. In many cases, it is one of these features, not precision level, that when specified properly yields the desired performance and or life.
Find the Bearing Load & Load Capacity
Bearing loads are generally defined as the reaction force a component places on a bearing when in use.
When choosing the right bearing for your application, first you should find the bearing’s load capacity. The load capacity is the amount of load a bearing can handle and is one of the most important factors when choosing a bearing.
Bearing loads can either be axial (thrust), radial, or a combination.
An axial (or thrust) bearing load is when force is parallel to the axis of the shaft.
A radial bearing load is when force is perpendicular to the shaft. Then a combination bearing load is when parallel and perpendicular forces produce an angular force relative to the shaft.
