Pillow blocks are bearing housings used to support shafts and house insert bearings. They provide alignment, protection, and mounting for reliable operation in mechanical drive systems. Key benefits Secure shaft support: Maintains precise shaft alignment to reduce wear, vibration, and downtime. Bearing protection: Shields bearings from contaminants and supports proper lubrication pathways for longer bearing life. Easy maintenance: Accessible mounting and, where applicable, lubrication provisions simplify inspection and service. Function and compatibility Supports insert bearings: Accommodates standard insert bearings sized to fit common shaft diameters. Mounting flexibility: Available configurations include twobolt and fourbolt foot mounting to fit standard frame patterns. Spares and interchangeability: Designed to align with conventional bearing housings and mounting footprints for easy replacement. Size, material, and performance Variable bore sizes: Offered in a range of bore options to fit various shaft sizes and machine requirements. Material options: Typically cast iron housings, with stainless steel or other materials available in select models for different environments. Durability and load handling: Built to provide rigid support, resist wear, and maintain alignment under operating loads to improve uptime. 23 practical use scenarios Conveyor systems: Support drive and idler shafts along a belt conveyor, maintaining consistent rotation and reducing shaft wobble for reliable material handling. Machine tools and automation: Provide stable shaft support for feed drives, rollers, or rotating assemblies in automated equipment, helping to preserve precision and reduce maintenance. Outdoor or harsh environments: In applications exposed to dust, moisture, or washdowns, stainless steel or specially finished pillow blocks offer corrosion resistance while maintaining dependable operation. Notes for selection and installation Verify bore size and mounting pattern: Choose a model that matches the shaft diameter and the frame's mounting footprint. Consider environment and material: Select material and finishes suited to exposure conditions (e.g., stainless steel for corrosive or washdown contexts). Check maintenance features: Look for lubrication provisions, sealing options, and accessibility for bearing inspection when selecting a model.
