What are barrel roller bearings?

Barrel roller bearings are types of spherical roller bearings that feature single rows of roller bearings, which are self-aligning. These types of roller bearings possess a solid outer ring that has a concave raceway, solid inner rings having two ribs and a bore, and a cage with barrel rollers. Barrel roller bearings cannot be taken apart. As far as their functional ability is concerned, barrel roller bearings are only capable of carrying a low axial load. 

Importance of barrel roller bearings

Barrel roller bearings are equipped with certain impressive functional abilities that make them important components for a wide range of industrial equipment and applications. First and foremost, the spherical outline of their outer and inner rings, as well as the barrel rollers, make them effortlessly adjustable in angles, enabling them to rectify misalignments effectively. Additionally, barrel roller bearings are capable of absorbing both radial and axial forces, and can accommodate very high shock loads. 

Applications

Barrel roller bearings are typically well-suited for applications that involve high radial shock-type loads and frequent misalignments. As such, they are often used across different industries, including manufacturing, aerospace, military, and so on. Barrel roller bearings are most commonly found in:

• Heavy machinery
• Fans
• Electric motors
• Pumps 
• Gearboxes
