Product Description Product Description Pillow Block Bearing UnitsPillow block bearing units are integrated assemblies consisting of a bearing insert and a mounting housing. They are widely used in agricultural machinery, conveyor systems, construction equipment, and various industrial applications. The bearing insert typically features a spherical outer surface, which fits into a housing with a spherical inner bore. This design allows for a variety of structural options and ensures excellent versatility and interchangeability.The insert bearing, usually a spherical bearing, provides a self-aligning function that compensates for minor installation misalignments. These units are easy to install and are often equipped with a dual-seal structure to effectively block dust and contaminants, making them suitable for harsh working environments.The WKL series offers a wide range of pillow block units that comply with ISO, North American, and Japanese Industrial Standards, covering diverse application needs across global markets. Depending on specific usage and installation conditions, users can choose from multiple combinations of bearing inserts and housing types.Common Housing Types Include:Cast Housings:Pillow block (P), Narrow pillow block (PA), High center pillow block (PH)Square flange (F), Round flange (FC), Square raised flange (FS)Diamond flange (FL), Circular flange (C), Take-up unit (T)Hanger unit (HA), Adjustable diamond flange (FA), Hanging unit (FB)Pressed Steel Housings:Round pressed housing (PF), Diamond pressed housing (PFL)Triangular pressed housing (PFT), Pillow block pressed housing (PP)Naming Convention Example:Each unit name combines the insert bearing model with the housing type. For instance, a UC205 bearing with set screws mounted in a standard pillow block housing is referred to as UCP205. Thanks to their strong interchangeability, bearing inserts of the same size can be mounted in various housing types with compatible dimensions.Product Parameters FAQ 1. What is a pillow block bearing?A pillow block bearing is a mounted bearing unit that consists of a housing and an insert bearing. It allows easy mounting and alignment of shafts while supporting radial and axial loads.2. What are the common applications of pillow block bearings?Pillow block bearings are widely used in agricultural machinery, conveyor systems, construction equipment, textile machinery, and food processing equipment due to their durability and ease of installation.3. How to select the right pillow block bearing model?Model selection depends on shaft diameter, load requirements, operating environment, and mounting type. For example, UCP205 fits a 25mm shaft and is used in standard load applications.4. What materials are pillow block bearings made from?The bearing insert is typically made of chrome steel or stainless steel, while the housing is usually cast iron or pressed steel. Some models are available in thermoplastic or stainless materials for corrosion-resistant applications.5. What is the difference between UCP, UCF, and UCFL types?UCP: Vertical (pedestal) mounted housingUCF: Square flange mounted housingUCFL: Two-bolt flange (oval) housingEach type fits different mounting requirements.6. Are pillow block bearings interchangeable?Yes, the insert bearings (e.g., UC205) are usually interchangeable between housings of the same series and bore size, allowing flexibility in use and replacement.7. Do pillow block bearings require maintenance?Yes, most pillow block bearings come with grease fittings for periodic lubrication. Sealed types require less maintenance.8. Can pillow block bearings be used in harsh environments?Yes, many pillow block units have double-sealed structures and are designed to resist dust, moisture, and moderate chemical exposure. For extreme environments, stainless or thermoplastic types are recommendedDetailed Photos
