Radial ball bearings are subjected to load and strength requirements

- Mar 20, 2019-

Radial ball bearings are mainly subjected to radial bearings during operation. This is also the most common bearing. Generally, the deep groove ball bearings we see are radial bearings. There are many types of plain bearings, which can be divided into radial bearings (bearing radial loads) and thrust bearings (with axial loads) depending on how they are loaded.

 

A threaded hole in the lubricant cup is attached to the radial ball bearing. An oil hole is formed in the sleeve, and an oil groove is formed on the inner surface of the sleeve. The advantage of this type of bearing is that it is simple in construction and low in cost. It can only be detached from the end of the journal. For shafts of heavy machinery or shafts with intermediate journals, assembly and disassembly is inconvenient or impossible to install. Therefore, such bearings are often used in low-speed, light-load or intermittent machines, such as certain agricultural machinery, manual machinery, and the like.

 

The bearing shell of the radial ball bearing is made of a sliding bearing material with good friction reducing properties, including metal materials (such as copper alloy, aluminum alloy and babbitt) and non-metal materials (such as plastic, graphite, rubber and wood). Some metal materials with good friction reduction have low strength (such as babbitt), and only one layer is cast on the surface of the bearing with high material strength, which is called bearing lining.
