Roller Bearings

At ProSource we provide a wide variety of roller bearings, which are sometimes also called rolling-element bearings. These bearings are similar to ball bearings in that they are designed to carry loads and minimize friction. The difference? These bearings transmit loads using cylinder rolling elements, rather than balls. This difference helps maintain the separation between moving parts. Roller bearings can contain single or multiple rows of rolling elements. Also, the use of different roller shapes can further reduce friction and support both radial and axial loads.

Roller bearings extend the working life of: 

  • Wheels 
  • Pulleys 
  • Fans
  • Pumps
  • Compressors 
  • And more! 

They do this by reducing friction and enabling parts to move smoothly. These bearings have a wide, flat bearing to provide stability in high-speed applications with high radial loads. Radial loads exert force across the diameter (radius) of the shaft, such as those exerted by the load supported by a pulley or wheel. Tapered bearings, cylindrical bearings, and combination bearings support axial and radial loads, and needle bearings support high speed, high radial loads in confined spaces. Spherical bearings support heavy shock loads where misalignment is a risk, and tapered roller bearing cones and cups support high radial and axial loads.

Many types of these bearings are self-aligning and can overcome misalignment and mounting issues. This helps you cut down on maintenance, repair, and labor needs. These bearings come in a wide range of shapes and sizes, and can be customized for specialized situations. The use of flanges, cages, and multiple bearing rows can allow for higher performance. While these bearings can handle higher loads than conventional ball bearings, applications are limited to low-speed operations. 

Additional features include:

  • The support and guidance of rotating machine elements and transfer loads between machine components. 
  • High precision and low friction, which enables high rotational speeds and reduces noise, heat, energy consumption, and wear. 
  • Cost-effective and exchangeable machine elements that typically follow national or international dimension standards.

Frequently Asked Questions

  • What applications are roller bearings used in? They are used in a wide range of applications, from heavy equipment and machinery to power generation, manufacturing, and aerospace.
  • What are cylindrical roller bearings? They feature rollers that are longer than their diameter and can tolerate higher loads than ball bearings. 
  • Can cylindrical bearings carry heavy radial loads? Yes, they can and are able to be used in high-speed applications.
  • What are spherical roller bearings? They can carry heavy loads even when dealing with misalignment and shaft deflection. 
  • For spherical bearings, are sleeve adapters mandatory? They can be designed to have cylindrical or tapered bores for mounting with or without a sleeve adapter. 
  • Can spherical roller bearings handle axial loading in either direction? Yes, they can and can handle heavy shock loads. 
  • What are the bore dimensions for spherical bearings? They are available in bore dimensions ranging from 20 mm to 900 mm.
  • What are needle roller bearings? They are thinner than conventional bearings and can be designed with or without an inner ring. 
  • What environments are needle bearings used in? They are perfect for radial space constraints in heavy-load, high-speed applications. 
  • What are taper roller bearings? They can support radial and thrust loads. 
  • What axial loads can taper bearings handle? Only unidirectional axial loads, so a second laterally reversed bearing is required for counterstay.
