Pillow Seat Bearing

Pillow block bearings are a common bearing type, also known as block bearings. It consists of a bearing with a spherical outer ring and a housing with a spherical inner ring. This kind of bearing can bear large radial load and axial load on the horizontal axis.Pillow block bearings are usually made of cast iron or steel for high strength and rigidity. They are commonly used to support the shafts of rotating mechanical equipment such as fans, pumps, compressors, etc. Pillow block bearings are easy to install and maintain, making them suitable for a variety of industrial applications.The working principle of the pillow block bearing is to support and transmit the load through the rolling contact between the spherical inner ring and the spherical outer ring. They are usually supplied with grease or oil to reduce friction and wear and provide good bearing lubrication.
