Tapped base bearings are a type of pillow block bearing specializing in high speed operation, reversing, and indexing applications. Pillow block housing units are used in applications where the mounting surface lies parallel to the shaft axis.Depending on the application, these housing units can be made of various types of cast iron, steel, or aluminum. Aluminum housing units are more suitable for higher temperature and load capacity applications compared to other materials. A variety of bearing insert
types can be used with tapped base pillow block housings. Standard ball bearings are designed to reduce friction for higher load applications; the width of the inner ring can impact bearing performance. 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. A multitude of seal types, such as rubber seals or metal shields, are available to protect bearing lubrication
. Typically a grease nipple is included for easy re-lubrication. 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 formidable range of tapped base pillow block bearings of different manufacturers, materials, and styles to suit any application.
