The Complete Guide to Pillow Block Flange Bearings: Everything You Need to Know

Pillow block flange bearings are a type of bearing that is used to support a shaft in a fixed position. They are typically made of cast iron or steel and have a spherical outer surface that fits into a matching housing. The inner surface of the bearing is lined with a bearing material, such as babbitt metal or bronze, which provides a low-friction surface for the shaft to rotate on. Pillow block flange bearings are often used in applications where the shaft is subjected to heavy loads or where there is a need for precise alignment.

Types of Pillow Block Flange Bearings

There are many different types of pillow block flange bearings available, each with its own unique set of features and benefits. Some of the most common types include:

Type	Features	Benefits
Fixed	The bearing is fixed in place and cannot move	Provides a rigid support for the shaft
Floating	The bearing is allowed to move slightly in the housing	Compensates for misalignment and reduces stress on the bearing
Self-aligning	The bearing is able to align itself with the shaft, even if the shaft is not perfectly aligned	Ensures smooth operation and extends bearing life

How to Choose the Right Pillow Block Flange Bearing
