Mounted insert Bearings
SUMMARY
Pillow block bearings are a type of mounted bearing designed to support rotating shafts and reduce friction between the shaft and housing. These bearings feature a ball bearing insert housed in a solid block, often made of cast iron, steel, or polymer materials, with a variety of housing designs for different installation needs. They are commonly used in industrial machinery, conveyor systems, and agricultural equipment, providing reliable performance and easy maintenance with a compact, self-aligning design.
