Pillow blocks are bearing housings designed to hold insert bearings and mount to a supporting surface, providing stable support for rotating shafts in machinery. Key benefits Precise shaft alignment and smooth rotation to reduce wear and vibration. Protection for bearings from dust and contaminants when seals are available. Easy installation and maintenance with standard mounting patterns and accessible lubrication points. Durable construction available in multiple materials to suit different environments. Reliable performance for typical industrial applications with consistent operation. Key attributes Function: bearing housing for insert bearings; supports rotating shafts in linear and rotary equipment. Compatibility: designed for common shaft sizes and insert bearing configurations and compatible with standard mounting accessories. Size: offered in a range of sizes to fit different shaft diameters and load requirements. Material: available in multiple materials to match environmental and durability needs. Performance: engineered for stable alignment, low maintenance, and long service life in industrial settings. 23 use scenarios On a conveyor line, pillow blocks support drive and idler shafts to maintain belt alignment and smooth motion. In a milling or drilling machine, pillow blocks provide rigid support for a feed shaft, improving stiffness and accuracy. In automation and packaging systems, pillow blocks form the backbone of linear axis assemblies for consistent travel and reliable operation.
