Pillow Block Bearings Standard Duty Concentric Locking

Pillow block bearings are a type of mounted bearing. They consist of a housing (a mounted block) and an insert bearing that is self-aligning. The housing, which is perpendicular to the shaft, features bolt holes that allow it to be secured to a foundation which runs parallel to the running shaft. Pillow block bearings function as support for rotating shafts and couplings in mechanical power transmission systems. This type of mounted bearing is quite versatile. It is suitable for a wide range of applications including rolling mills, ventilation systems, paper machines, conveyor belt rollers, and long shafts connecting motors and industrial gearboxes.

Take note that while the terms pillow block bearings and plummer blocks are sometimes used interchangeably, they are actually not the same. These two types of mounted bearings are used in different applications. Pillow block bearings are typically used for lightweight applications while plummer blocks are designed for high power, heavier load applications.

Pillow block bearings are available in a variety of types based on their housing construction - solid and split types - and the type of bearing used - plain, ball, roller (tapered, spherical, and needle roller bearings), and hydrodynamic bearings. These bearings can also be further categorized based on the shaft securing method used. Pillow block bearings that feature a concentric pillow block lock use tapered or adapter sleeves placed between the shaft and the bearing to ensure little vibration during high running speeds.
