Maximum load In general, the maximum load of a ball bearing is proportional to the outer diameter of the bearing times the width of the bearing (where the width is measured in the direction of the axis). Ball bearings tend to have a lower load capacity than other types of bearings due to the smaller contact area between the balls and the races. In order for a bearing to have its rated life at its rated load, it must be lubricated with a lubricant (oil or grease) that has at least the minimum dynamic viscosity (usually referred to the Greek letter) for that bearing. Ball bearings are designed to connect machine parts so that they absorb as little friction as possible when sliding against each other during their intended operations. When a lateral torque is applied to a radial bearing with a depth groove, the rolling elements apply an uneven force to the outer ring in the form of an ellipse, concentrating in two areas on opposite sides of the outer ring. A more cost-effective arrangement of the bearing outer ring with similar advantages is a snap ring groove at both ends of the outer diameter. Part of his task was to ensure that the textiles were produced efficiently, which obliged him to regularly monitor the equipment and production process. The advantage of a slot filling bearing is that more balls can be mounted (even if a complete complement design is possible), which results in a higher radial load capacity than a Conrad bearing of the same dimensions and material type. For small bearings, this is best done with a press, since tapping with a hammer damages both the bearing and the shaft, while for large bearings the necessary forces are so great that there is no alternative to heating a part before installation, so thermal expansion allows a temporary sliding fit. Since there is little surface contact between the balls and races, ball bearings usually have a lower load capacity for their size than other bearings. If this is the case, it can significantly increase the stresses in the bearing, which can often invalidate general rules of thumb in relation to the relationships between radial and axial load. Angle contact bearings support combined loads (load in both radial and axial directions), and the contact angle of the bearing should be adjusted to the respective relative proportions. A 4-point angular ball bearing A ball bearing for skateboard wheels with a plastic cage A ball bearing is a kind of ball bearing that uses balls to maintain the separation between the bearing breeds. The housing for such bearings can consist of a through hole of uniform diameter, but the entrance surface of the housing (which can be either the outer or inner surface) really needs to be machined normally to the axis of the hole. Again, this allows more balls, including full ball complement, but unlike either slitting or relieving racing designs, it can support significant axial load in both directions. Like angular contact bearings, deep groove bearings support both radial and axial loads without selecting the contact angle to allow the relative proportion of this load capacity to be selected. Slot Fill In a slot-filling radial bearing, the inner and outer breeds are notched on a surface so that when the notches are aligned, balls can be slipped into the resulting slot to mount the bearing. While the ceramic material itself is stronger than steel, it is also stiffer, which leads to increased stresses on the rings and, as a result, reduced load capacity. If the outer ring is not strong enough, or if it is not sufficiently stretched through the supporting structure, the outer ring deforms from the lateral torque voltage to an oval shape until the gap is large enough for the roller elements to escape. Integrated shaft ball bearings An integrated shaft ball bearing has two raceways on the shaft that allow integration with the inner ring and the shaft of two ball bearings. Conrad bearings have the advantage of being able to withstand both radial and axial loads, but have the disadvantage of lower load capacity due to the limited number of balls that can be loaded into the bearing assembly. A lateral torque on a radial bearing also exerts pressure on the cage, which keeps the rolling elements at equal distances, as the rolling elements try to slide all together at the point of the highest lateral torque.
