Pillow blocks with bearings have self-aligning properties and are easy to mount and dismount. They are widely used in various types of machinery, especially in agricultural, textile, metallurgical, mining, and various conveying applications. With a self-aligning structure, they can compensate for alignment errors or flexing of the shaft.
A pillow block bearing is a pedestal used to provide support for a rotating shaft with the help of compatible bearings & various accessories. The assembly consists of a mounting block which houses a bearing. The block is mounted to a foundation and a shaft is inserted allowing the inner part of the bearing / shaft to rotate. Set screws, locking collars, or set collars are commonly used to secure the shaft. Bearing housings are usually made of grey cast iron. However, various grades of metals can be used to manufacture the same, including ductile iron, steel, stainless steel, and various types of thermoplastics and polyethylene-based plastics. The bearing element may be manufactured from 52100 chromium steel alloy (the most common), stainless steel, plastic, or bushing materials such as SAE660 cast bronze, or SAE841 oil impregnated sintered bronze, or synthetic materials.
