What is roller bearing?
A roller bearing is a cylindrical or spherical object that aids in the movement of items, typically those that are heavy or large. Roller bearings are designed to reduce friction between moving parts. Roller bearings have a wide surface area to provide stability at any speed. There are many types of roller bearings available, depending on the application that you need them for.
What are the types of roller bearings?There are thousands of different types of roller bearings available to meet specific application requirements. Emerson Bearing offers a broad selection of roller bearings, including the following popular types:
Cylindrical roller bearings
These bearings feature 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.
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. Available with various internal clearances and retainer options, spherical roller bearings can handle axial loading in either direction as well as heavy shock loads. These spherical roller bearings are available in bore dimensions ranging from 20 mm to 900 mm.
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 needle roller bearings are offered with inch or metric seals.
Taper roller bearings
These bearings can support radial and thrust loads. They can only handle unidirectional axial loads, so a second laterally reversed bearing is required for counterstay. These taper roller bearings are available in inch and metric sizes. Roller bearings are used in a wide range of applications, from heavy equipment and machinery to power generation, manufacturing, and aerospace.
What are roller bearings used for?
Roller bearings can be used anywhere that you see moving parts working together. Roller bearings are used in pulleys and fans. They will also be found in wheels. Since the roller bearing can be used in so many different scenarios, they are seen across a wide range of industries. The roller bearing will help increase the productivity and long term durability of a product.
