Split Pillow Block Bearings

Split Pillow Block BearingsSplit pillow block bearings have been around since the industrial revolution and were designed for improving application versatility and ease of maintenance; they are also commonly referred to as Plummer block bearings. These versatile assemblies can accept a range of shaft sizes at higher loads than other mounted bearing types. The SAF series is the most common series of split pillow block bearings, accommodating five bearing types, four sealing options, and two mounting methods. We also offer the SAW series split pillow block bearings which can accommodate higher load capacities. Additionally, we have the SDAF split pillow block bearings, typically found in high shock-load environments such as steel mills, mineral processing facilities, and more.

Features of split pillow block bearings

Our high-strength split pillow block bearings utilize several features to exemplify quality, durability, and performance. First, our split housings are made from high-grade cast iron and reinforced with thin webs for heat transfer and ribs to prevent deformation from over-tightening. The SAF housings also feature two threaded plugs on top of the housings for grease fittings and various testing equipment, along with two drain plugs on opposite sides of the housing at the bottom faces. Most of these units are supplied with Labyrinth Seals (LER) and a stabilizing ring (please confirm with your customer service agent for specific sizes). The spherical roller bearings provide superior performance and are made to precision standards from high-quality steel material. Made to perfection, our adapters, seal rings, and stabilizer rings are sure to impress! For additional information or to get a quote, please contact our customer support team, and we will be happy to assist you.The split pillow block bearings are the most versatile mounting components. The product design is halved, and the cover and the bottom can be split, so it is convenient to install and debug the equipment. For demanding equipment, the split pillow block bearings are also designed with double stud holes and four stud holes. These components primarily withstand the radial loads directly experienced by the inner base. Used on demanding and high equipment.The split pillow block bearings accommodate a wide range of shaft sizes and can withstand high loads. Heavy-duty housings are available in grey cast iron as standard, providing greater flexibility in sealing and lubrication (with grease or oil). The split pillow block bearings can be used in equipment such as belt processing equipment in steel mills, fans, and blowers, felt rolls and drying cylinders for the paper industry, crushers for the ore processing industry, hammer mills, and drying ovens.
