Engineered for specialized industrial machinery, compact conveyor assemblies, and light-to-medium power transmission applications, the CSB209-26 1-5/8 inch insert ball bearing combines precision 1-5/8" x 85mm x 19mm dimensions with a specialized profile for space-constrained mountings. Designed for smooth rotation and reliable shaft retention, it serves as an exact direct replacement for Peer/Link-Belt FHSR209-26 / SL-26, Fafnir/FAG YA110RR / AY1-5/8-NPP, Asahi/NTN ASS209-110N / SB209-26, Dodge/IPTCI BR209-26 / CSB209-26N, and Browning/Morse SLS-126.

✨ Engineering Architecture & Performance Merits
Space-Saving Narrow Profile: Engineered with an optimized 19mm width to fit into restricted industrial housings where standard width bearings cannot be accommodated.
Spherical Outer Ring Design: Self-aligning outer contour compensates for minor angular shaft misalignments during operation.
Enhanced Sealing System: Equipped with precision-fitted protective seals to effectively retain high-grade grease while blocking dust, dirt, and moisture.
Pre-Lubricated & Maintenance-Ready: Factory-filled with high-performance anti-friction grease for immediate, reliable deployment right out of the box.
🚛 Target Industrial Sectors & Deployment Fields
Compact Conveyor Systems: Lightweight roller beds, sorting lines, and material handling modular equipment.
Specialized Industrial Machinery: Textile equipment, packaging machinery, woodworking tools, and agricultural auxiliary drives.
Ventilation & Fan Units: Commercial air handlers and moderate-duty HVAC blower assemblies.
