 // A Parametric Bearing Pillow Block
 // A bearing pillow block, also known as a plummer block or pillow block bearing, is a pedestal used to provide support for a rotating shaft with the help of compatible bearings and various accessories. Housing a bearing, the pillow block provides a secure and stable foundation that allows the shaft to rotate smoothly within its machinery setup. These components are essential in a wide range of mechanical systems and machinery, playing a key role in reducing friction and supporting radial and axial loads.
