Roller Bearings

Roller bearings are similar in profile to ball bearings but rather than using balls to rotate they utilise cylinder rolling elements. Roller bearings carry a load by placing rolling elements such as rollers between outer rings and inner rings called races. This allows the bearing to maintain separation between moving parts, helping to reduce rotational friction and noise. For applications requiring high radial and axial load support, roller bearings are ideal and are available in a variety of designs.

Types of roller bearings

There are a wide range of roller bearing available in various sizes and types, each suited to specific applications. Popular types of roller bearings include:

  • Cylindrical roller Bearing - Ideal for handling low thrust and high radial loads at high speeds
  • Spherical Roller Bearings - These feature two rings on the inner raceway that handle loads and misalignment concerns
  • Needle Roller Bearings - This type of bearing utilises long and thin cylindrical rollers to support radial loads
  • Tapered Roller Bearings - Tapered outer, inner rollers and raceways accommodate the simultaneous thrust and radial loads of this type of bearing
