Pillow Block Bearings A pillow block bearing provides stable support for a rotating shaft in a compact, ready to mount housing. It aligns the shaft and reduces friction, helping components move smoothly with less wear. The integrated housing holds an insert bearing for a self contained unit that simplifies installation and replacement. Key benefits Easy installation and alignment with a flat mounting base and predrilled holes for secure attachment to a frame Reliable shaft alignment maintained by a rigid housing Maintenance efficiency through seals that retain lubricant and replaceable inserts for longer service life Versatility with housing materials such as cast iron, steel, and aluminum to suit environment and load Broad compatibility with standard insert bearings for flexible shaft size options and easy stocking Solid performance for continuous operation with consistent radial load support in typical industrial applications Attributes to consider Function: supports rotating shafts, provides radial load support, helps maintain alignment Compatibility: accepts standard insert bearings, multiple bore sizes, and mounting configurations (foot or flange) Size: bore size and overall dimensions vary; select to match shaft diameter and space constraints Material: housing materials (cast iron, steel, aluminum); inserts (steel or stainless); seals (open, shielded, or sealed) Performance: load rating, speed capability, seal type, and lubrication method (grease filled or greaseable) Use scenarios Conveyor systems: supports the driven roller shaft to preserve alignment, reduce belt wear, and enable quick bearing replacement Milling and woodworking equipment: provides a sturdy drive shaft support with straightforward insert bearing service and maintenance Agricultural field equipment: backs rotating shafts in equipment like harvesters or balers while seals protect against dust and moisture How to select Match bore size to shaft diameter with appropriate clearance Choose housing material based on environment and weight considerations Select seal type based on exposure to dust, dirt, or moisture and planned maintenance intervals
