Roller Bearings and Its Types
Roller bearings which are also known as rolling-element bearings are very much the same to ball bearings because they have been created to carry a haul while minimizing friction. Roller bearings can transfer loads using cylinder rolling elements, rather than balls, to maintain the separation between moving parts of the bearing. For a more detailed look on roller bearings and their functions read the article below.
These functional bearings may possess single or multiple rows of rolling elements including but are not constrained to multiple rows that can significantly improve radial load capacity. Also, the use of different roller shapes can further reduce friction and support both radial and axial loads. While roller bearings can handle higher loads than conventional ball bearings, their applications are generally limited to low-speed operations. Some versions types of roller bearings are self-aligning, and are easily able to overcome misalignment and mounting issues — cutting down on maintenance, repair, and labor needs.
Roller bearings come in a wide range of shapes and sizes, and can be customized for specialized situations. Also, the use of flanges, cages, and multiple bearing rows can permit for better performance to meet certain criteria application needs. There are thousands of different types of roller bearings available to meet specific application requirements.
1. Cylindrical Roller Bearings
In terms of cylindrical roller bearings, these bearings display rollers that are longer than their diameter, and can tolerate higher loads than ball bearings. Our cylindrical roller bearings can carry heavy radial loads and are able to be used in high-speed applications. As for spherical roller bearings, these can carry heavy loads even when dealing with misalignment and shaft deflection. They can be designed to have cylindrical or tapered bores for mounting with or without a sleeve adapter. Found with many internal clearances and retainer options, spherical roller bearings can handle axial loading in either direction as well as heavy shock loads. These bearings are available in bore dimensions ranging from 20 mm to 900 mm.
2. Needle Roller Bearings
With regards to needle roller bearings, this type of bearing is thinner than conventional roller bearings and can be designed with or without an inner ring. Needle roller bearings are ideal for dealing with radial space constraints in heavy-load, high-speed applications. Drawn cup styles allow for high load capacities and large grease reservoirs while still offering a slim cross-section design. These bearings are offered with inch or metric seals.
3. Tapered Roller Bearings
Taper roller bearings are bearings that can support radial and thrust loads. They can only handle unidirectional axial loads, so a second laterally reversed bearing is required for counter stay. Taper roller bearings are available in inch and metric sizes. Roller bearings are used in a wide range of applications, from large machinery to power generation, manufacturing, and aerospace.
