Pillow block units are a type of mounting bracket that houses a bearing
. They are typically used in low-torque, light load applications, where the mounting surface is parallel to the shaft axis; they are designed for facilitating quick and easy mounting. Depending on the application, these housing units can be made of various types of cast iron, steel, or aluminum. Aluminum pillow block housings can handle higher temperature conditions and load capacity compared to other materials. Pillow blocks can be split or unsplit; the cap or housing element can be separated from the base of a split pillow block, while unsplit is one solid piece and is non separable. A variety of bearing insert types can be used with pillow block housings. Standard ball bearings are designed to reduce friction and have high load capacity. Needle roller bearings have particularly small rolling elements, normally with a cylindrical shape, and can have different specializations depending on the design. Roller bearings are the larger counter-part to needle roller bearings
, specialized for rotational motions and a wide variety of applications.Plain ball bearings are typically used in linear load applications, and are commonly constructed from bronze and metal alloy. Due to the wide variety of bearing inserts
, pillow block housing units can be used for a multitude of applications, such as agricultural machinery, conveyor systems, industrial fans, textile equipment, special machinery, and other industries like food and beverage processing and packaging. MRO Supply offers a wide selection of pillow block bearings of different manufacturers, materials, and styles to suit any application.
