Journal bearings generally have lower initial costs than rolling-element bearings. The ball contact angle and the shoulder that is machined in the outer ring, provide higher axial load capacity in one direction. Load type, magnitude and direction of loads are all key in determining the proper type of ball bearing. The static load rating relates to limiting loads applied to non-rotating bearings. The boundary dimensions for certain series of bearings are defined in various standards, such as ABMA, JIS and ISO. If the bearing selected is equipped with rubber seals (2RS), it has molded seals made from Buna-N and bonded to a steel inserts for strength. This means that these bearings are designed to accommodate combined loads, i.e. As with any ball bearing, more balls means more surface area for the distribution of radial load. When you choose radial load, it means that the bearing will roll or rotate when it is under tension. Radial play, or internal clearance, is the internal radial looseness in a bearing and is the measured value of the total radial movement of the outer ring with respect to the inner ring in a plane perpendicular to the bearing axis.Ball bearings are assembled to radial play values depending upon a desired range.
