Pillow Blocks

High-Quality Pillow Blocks for Mechanical and Industrial Applications

Pillow blocks are essential components in rotating systems, used to support and position shafts with safety and stability. 

With a durable housing and an insert bearing, they ensure proper alignment and help reduce friction in industrial, agricultural, automotive, and many other machines.

At PGN Bearings, you'll find pillow blocks designed for high performance, durability, and easy installation. Explore our selection and find the right solution for your project.

What Are Pillow Blocks?

Pillow blocks are metal housings that contain bearings and are used to support and align rotating shafts safely and efficiently.

Designed for easy mounting on flat surfaces, they can handle moderate radial and axial loads, making them a practical and reliable solution for various mechanical systems.

While the term “pillow block” is widely used, it’s often confused with “plummer blocks.” The key difference lies in their size and application: plummer blocks are typically larger and built for heavier loads and more demanding industrial environments. 

Pillow blocks, on the other hand, are more compact and suitable for a wider range of uses, offering versatility and ease of installation.

Other common names for pillow blocks include “bearing housing,” “mounted bearing unit,” or simply “shaft support block.”

How Do Pillow Blocks Work?

Pillow blocks work as complete support units, combining a robust metal housing with an insert bearing. This structure offers both stability and easy mounting, allowing the rotating shaft to spin smoothly with minimal friction and wear.

The internal bearing — known as an insert bearing — is precisely aligned within the block to ensure efficient operation. It helps reduce friction between the shaft and the support, extending the equipment’s lifespan and maintaining consistent performance, even in environments with vibration or varying loads.

These components are widely used in agricultural machinery, ventilation systems, conveyor belts, manufacturing equipment, and more. In all these cases, pillow blocks provide reliable shaft support and help keep operations running smoothly.
