Indentation load capacity has been reported for relatively large (12.7 millimeters diameter) ceramic (Si3N4) indenter balls pressed against flat plates of 60NiTi. In order to develop damage load threshold criteria applicable to a wide range of bearing designs and sizes, the effects of indenter ball radius and the accuracy of interpolation of the Hertz contact stress relations for 60NiTi must be ascertained.

Effects of geometric parameters on static load

The compartments could contain different ball sizes. Large to small from the feed end. Some mills have a conical section. In the conical section near the discharge, fine particles preferentially move into the conical section thereby creating segregation. This type has low feed capacity and is rarely used in the metallurgical industry.

Technical Information: Ball bearing types, selection

Radial load capacity is higher in this bearing than in the standard deep-groove construction, but high-speed performance and thrust-load capacity is impaired. When large thrust loads in one direction are coupled with radial loads, angular contact ball bearings, Figure 2(c), are usually superior.

Maximum Capacity Series Deep Groove Radial Ball

2021-5-27  Maximum capacity bearings incorporate a filling slot in the inner and outer ring so that they can be loaded with additional balls for greater capacity. This makes them ideal for applications requiring heavy radial loads and low speeds where thrust loads are comparatively low. They are available with metal shields (ZZ) or rubber seals (2RS).

Why Do Hitch Extenders Reduce Hitch Capacity but

Longer ball mounts typically have lower capacities than standard ball mounts, so that is generally how they reflect the lower capacity from the increased leverage. 2-1/2 inch hitches also follow a similar train of thought. While the rule doesn't necessarily apply to the hitch it does apply to the extension pieces.
