Overview of rolling bearings
Rolling bearings (also called rolling bearings) are similar to ball bearings in that they are designed to carry loads while minimizing friction.
However, rolling bearings use cylinder rolling elements instead of balls to transmit the load to maintain the spacing between the moving parts of the bearing.
These multi-purpose bearings can contain single or multiple rows of rolling elements. Multiple rows can significantly improve the radial load capacity. Similarly, the use of different roller shapes can further reduce friction and support radial and axial loads.
All options and sizes required
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 and installation problems-reducing maintenance, repair and labor requirements.
The rolling bearing has 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 commonly used types:
1.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.
2.Spherical roller bearing
Even in the face of misalignment and shaft deflection, they may be subject to heavy loads. They can be designed with cylindrical or tapered holes for installation with or without sleeve adapters. Spherical roller bearings have various internal clearances and retainer options, which can withstand axial loads in any direction and strong impact loads. The bore diameters of these bearings range from 20 mm to 900 mm.
3.Needle bearing
This type of bearing is thinner than traditional rolling bearings and can be designed with or without an inner ring. Needle roller bearings are the ideal choice for heavy-duty, high-speed applications to cope with radial space constraints. The drawn cup shape enables high load capacity and large grease pools while still providing a slim cross-sectional design. These bearings have an inch or metric seals.
4.Tapered Roller Bearings
These bearings can withstand radial and axial loads. They can only withstand one-way 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.
