What Is a Spigot Bearing?

A spigot bearing is a type of bearing that is used to support a rotating shaft. It consists of a cylindrical outer ring with a tapered bore and a flanged inner ring with a matching taper. The shaft is inserted into the bore of the outer ring and the inner ring is then pressed onto the shaft, causing the flanges of the inner ring to engage with the tapered bore of the outer ring. This creates a tight fit between the shaft and the bearing, which prevents the shaft from moving axially or radially.

Spigot bearings are often used in applications where high loads and high speeds are involved, such as in automotive engines and gearboxes. They are also used in applications where precision is important, such as in machine tools and robotics.

There are several advantages to using spigot bearings, including:

* They provide a high degree of accuracy and precision.

* They can support high loads and high speeds.

* They are relatively easy to install and maintain.

* They are relatively compact in size.

However, there are also some disadvantages to using spigot bearings, including:

* They can be relatively expensive.

* They can be sensitive to misalignment.

* They can be noisy at high speeds.

Overall, spigot bearings are a good choice for applications where high accuracy, precision, load capacity, and speed are required. However, they can be relatively expensive and sensitive to misalignment, so they should be used with caution in applications where these factors are critical.
