(Actually roller bearings) Rolling bearings in which cylindrical rollers are used as rolling elements.
Roller ball bearings are a type of rolling bearing used in rotating applications to support radial and axial loads. Unlike deep groove ball bearings, roller ball bearings have cylindrical rollers instead of balls that move along the inner and outer rings.
The rollers in a roller ball bearing are usually longer than the balls in a deep groove ball bearing and can therefore support higher radial loads. There are different types of roller ball bearings, including
1. cylindrical roller bearings: these are the most commonly used roller ball bearings and consist of cylindrical rollers that run between an inner ring and an outer ring.
2. spherical roller bearings: These bearings have spherical rollers and are capable of supporting both high radial and axial loads.
3. tapered roller bearings: These bearings have tapered rollers and are capable of supporting both radial and axial loads, whereby the axial load can be greater in one direction than in the other.
Roller ball bearings are used in a variety of industries, including automotive, aerospace, heavy industry, engineering, electronics and power generation. They are particularly useful in applications that require high loads and speeds and where long life and high reliability are important.
