Bearing Pillow Block | blogger.googleusercontent.com Pillow block bearings are used in most industrial applications today because of the bearing housing's relatively simple construction. The most noticeable part of this kind of bearing unit is the housing with a mounted bearing insert.
Pillow block bearings are well known for their complex engineering design, which consists of a rotating shaft, bearing support, and an appropriate bearing unit composed of rollers and ring raceways. In industrial sectors where a hygienic bearing solution and great performance are required, these housing units with bearings are mostly used. With cast iron or pressed steel housing in internationally accepted designs, series, and dimensions, they are intricately designed to provide higher durability, better interchangeability, and greater performance. A bearing pillow block is made to use as a single-piece unit or as assembly pieces based on the industrial requirement. The entire unit is fastened to a supporting or flat surface using a mounting base. To improve production efficiency, pillow blocks with the proper bearing units are used in industrial applications like textile machinery, material handling systems, food and beverage processing machines, and pharmaceutical machinery. How Can You Design a Suitable Bearing Pillow Block? When choosing the bearing housing type for different applications, you should consider a number of factors including the diameter, size, and height of the shaft, the speed, and the load-handling capacity. Other than these, you should look for the proper bearing type and ring raceways to hold the rollers in place. You can choose a suitable bearing from the plain, ball, needle, cylindrical, or spherical types depending on your requirements and application. Ball or roller bearings, ring raceways, and a separator are needed to make a pillow block bearing. The machine runs smoothly because of the minimal friction during the operation of logarithmic profiles of the rolling elements. Rolling elements with tapered, conical, crowned-end or spherical shapes are used in the bearing unit. Pillow block bearings can support heavy axial, radial, or combined loads thanks to their larger contact area. You can choose a bearing pillow block unit for specific applications by taking into account the information above. Learn about the various Pillow Block Bearing design variations Due to recent developments in bearing technology, better bearing pillow block variants are being developed to meet the requirements of industrial applications. Here are some popular ones: • Cast Iron Housing Type: An in-built lubrication mechanism in this specific bearing unit carries out periodic lubrication and re-lubrication. It helps to extend service life. • Pressed Steel Housing: Made using zinc-coated steel, which is chromium-free and inhibits corrosion, is used to make the bearing unit. Its applications typically involve restricted loads at slow speeds. • Composite Housings: You can find lightweight glass fiber, a reinforced PA6 material, used in this housing type to support high-speed applications. Your best option for a bearing pillow block will depend on your industrial application and its specifications.
