Pillow blocks Key benefits Provides rigid support for a rotating shaft, keeping it aligned to reduce wear and vibration. Encloses the bearing insert to protect against dust, debris, and incidental impacts, helping extend service life. Easy to install with standard mounting patterns and widely compatible bore sizes for flexible system integration. Available in multiple material options to suit different environments and load requirements. Maintains lubrication and reduces maintenance with sealed or greased bearing options and replaceable inserts. Function and features Function: A bearing housing that holds an insert bearing in a fixed position, supporting radial loads and maintaining shaft alignment during operation. Compatibility: Designed to accept common bearing inserts and match standard mounting hole patterns for easy replacement and retrofit. Size options: Offered in a range of bore sizes and housing dimensions to fit various shaft diameters and space constraints. Material and finish: Available in durable cast iron, steel, or aluminum variants, with finishes suitable for general use or corrosion resistance as required. Performance: Built for reliability in continuous operation, with predictable load handling, stable alignment, and straightforward maintenance. Materials and finishes Cast iron pillow blocks for durability and vibration damping. Steel variants for higher load capacity and impact resistance. Aluminum options for lighter weight and heat dissipation in suitable applications. Optional finishes or coatings to enhance corrosion resistance in harsh environments. Installation and maintenance Mounting: Align with existing mechanical layouts using standard mounting holes and bolt patterns to simplify replacement. Bearings: Use replaceable or serviceable insert bearings as specified for the chosen model. Lubrication: Choose from grease or oil lubrication options, with seals and shields available for dust and moisture protection. Maintenance: Regular inspection of mounting integrity, seals, and lubrication levels to sustain performance. Applications and use scenarios Conveyor systems: Support drive shafts and rollers along the line, maintaining alignment for smooth, lowfriction operation and easy belt or chain drive maintenance. Machine tools and automation: Hold precision shafts in CNC or automated equipment, preserving accurate positioning and minimizing wear on spindles and feed mechanisms. Industrial machinery and agriculture: Provide reliable shaft support for fans, blowers, pumps, augers, and other rotating components in demanding environments, with options for enhanced protection where dust or moisture is present.
