Roller Bearings

Roller Bearings are rolling-element bearings that utilizes cylindrical rollers to sustain the division between moving parts of the bearing. They are designed to carry a load while minimising friction.

The impetus of a roller bearing is to lessen rotational friction and support radial and axial loads. They are versatile as they can consist of single or multiple rows of elements in which the latter can considerably improve radial load capacity.

This best allows for the many applications necessitated across a multitude of potential purposes in which ball bearings can be used. Some of the more commonly found types of ball bearings are axial, deep-groove, angular contact, and preloaded pairs.

Types of Roller Bearings

Cylindrical Roller Bearings

Unlike Ball Bearings, Roller Bearings are bearings in which cylinders are used as the rolling elements. Cylindrical roller bearings have a wider contact area with the outer ring as they distribute loads across a broader surface. Consequently, they have a generally higher radial load capacity and are appropriate for high speeds.

Needle Roller Bearings

In essence, needle roller bearings are cylindrical roller bearings but with a length 3 to 10 times their diameter. Needle bearings utilise small & cylindrical rollers. Therefore, they have a rather high radial load capacity as the ratio of the bearing outside diameter to the inscribed circle diameter is small.

Spherical Roller Bearings

Spherical Roller Bearings are specially intended to work in applications with severe misalignments be it from shaft deflection or mounting. These bearings are also extremely resistant to shock loads. Spherical Roller Bearings are made to be more sturdy so as to carry heavier loads but at lower maximum speeds. They have barrel-shaped rollers between the inner ring and are self-aligning.

Benefits and Advantages


Has the ability to withstand momentary shock loads and has the accuracy of shaft alignment


Has a low cost of maintenance as no lubrication is needed while in service


Easy to mount and erect, thus application and installation are fuss-free
