Do you know Pillow block bearing?
2012/11/1

Pillow blocks are usually referred to the housings which have a bearing fitted into them & thus the user need not purchase the bearings separately. pillow block bearing wholesale are usually mounted in cleaner environments & generally are meant for lesser loads of general industry. These differ from "plummer blocks" which are bearing housings supplied without any bearings & are usually meant for higher load ratings & corrosive industrial environments. However the terms pillow-block & plummer-block are used interchangeably in certain parts of the world.

A pillow block bearing is a type of bearing that is housed within a cast-iron mounting bracket that doubles as the outer housing for the bearing. Typically manufactured from a gray cast iron, the pillow block bearing housing has provisions to allow the housing to be bolted down snugly.

The inner bearing component of the pillow block bearing is commonly a soft metal material, such as white metal, while the outer housing can be a split or single housing. Primarily designed for low-torque, minimal-load situations, this bearing is also designed to be used in clean environments within an industrial setting.

By using a pillow block bearing manufacture on a spinning shaft, the duty cycle of the shaft is greatly increased. The bearings prevent the shaft from distorting and wobbling while turning, thereby damaging any connective unions and weakening the very structure of the steel shaft.
