Introduction and classification application of rolling bearings

Jime

What is a rolling bearing?

Rolling bearings (also known as rolling bearings) are similar to ball bearings in that they are designed to minimize friction while carrying loads.

However, rolling bearings use cylindrical rolling elements instead of balls to transfer loads in order to maintain spacing between the moving parts of the bearing.

These multi-purpose bearings may contain single or multiple row rolling elements. Multiple rows can significantly improve radial load capacity. Similarly, the use of rollers of different shapes can further reduce friction and support radial and axial loads.

Rolling bearings all options and size requirements

Although rolling bearings can withstand higher loads than traditional ball bearings, their applications are usually limited to low speed operation. Many types of roller bearings are self-aligning, which can easily solve misalignment installation problems, reducing maintenance, repair and labor requirements.

Rolling bearings come in a wide range of shapes and sizes and can be customized for special situations. Similarly, the use of flanges, cages, and multi-row bearings can improve performance to meet specific application requirements.

Types and applications of rolling bearings

There are thousands of different types of rolling bearings to meet specific application requirements. Emerson Bearings offers a wide selection of roller bearings, including the following common types:

Cylindrical roller bearings

These bearings have rollers longer than their diameters and can withstand higher loads than ball bearings. Our cylindrical roller bearings can withstand large radial loads and can be used in high-speed applications.

 

Spherical roller bearings

They may be subjected to heavy loads even in the face of misaligned axis deflection. They can be designed with cylindrical or tapered holes for installation with or without sleeve adapters. Spherical roller bearings have a variety of internal clearance and retainer options and can withstand axial loads and strong impact loads in any direction. These bearings range in diameter from 20 mm to 900 mm.

 

Needle roller bearings

This type of bearing is thinner than traditional rolling bearings and can be designed with or without inner rings. Needle roller bearings are ideal for heavy-duty, high-speed applications to cope with radial space limitations. The drawn cup shape allows for high load capacity and large grease pools, while still providing an elongated cross-sectional design. These bearings have inch or metric seals.

 

Tapered roller bearings

These bearings can withstand both radial and axial loads. They can only withstand unidirectional axial loads, so a second reverse bearing is required. Tapered roller bearings are available in inch and metric sizes.

Rolling bearings have a wide range of applications, from heavy equipment and machinery to power generation, manufacturing and aerospace.
