What is A Rolling Bearing?

A roller bearing is a type of rolling-element bearing that uses a cylinder (roller) instead of a ball.  Rollers are usually cylindrical, but can also be tapered, spherical or needle-shaped. Roller bearings transmit loads using cylinder rolling elements, rather than balls, to maintain the separation between moving parts of the bearing.

The International Organization for Standardization (ISO) defines roller bearings as components that facilitate rolling motion (as opposed to sliding movement) between parts experiencing loads and relative motion. These components encompass features with rolling tracks and rolling elements, with or without isolating or guiding elements.

What are The Types of Roller Bearings?

There are several types of roller bearings, each with unique characteristics and applications. The most common types include:

Why Use Roller Bearings And What are the Advantages?

Compared with ball bearings, roller bearings have the advantages of small starting torque, high rotational accuracy and easy selection. Roller bearings are named because the rolling bodies are needle rollers or rollers. Compared with ball bearings, they have higher loads of the same size, higher rotational starting torque and higher accuracy of rotation and runout, and are more suitable for oscillating motion. In addition, if the rolling elements are rollers, they are more resistant to shock loads.Here's a look at the advantages of rolling bearings? Take a look together:

  • Through line contact between the rolling elements and raceways, cylindrical roller bearings have a high radial load-carrying capacity and are suitable for high-speed applications. They are commonly used in large motors, machine tool spindles, axle shaft boxes, etc.

  • Compact and lightweight with narrower axial dimensions.

  • It can withstand large loads and have a long service life.

  • Suitable for mass production with stable and reliable quality and high productivity.

  • Transmission friction torque is much lower than fluid dynamic pressure bearing, friction temperature rises, and power consumption is low.

  • Axial dimensions are smaller than traditional hydrodynamic bearings.

  • Can withstand combined radial and thrust loads simultaneously.

  • The unique bearing design allows for excellent performance over a wide load-speed range.
