Pillow blocks, meanwhile, offer a more compact and lightweight alternative to plummer blocks. These housings, typically made of cast iron or thermoplastic materials, house ball bearings or sleeve bearings and are suitable for applications where space is limited or lighter loads are involved. Pillow blocks find widespread use in conveyor systems, agricultural machinery, and HVAC equipment, contributing to efficient operation and reliability. Despite their smaller size, pillow blocks provide robust support and play a crucial role in maintaining the integrity and functionality of mechanical systems across various industries. Both types of bearing housings are indispensable components, ensuring the smooth operation and longevity of machinery in diverse applications.
