Browning HN50B17 Idler

The Browning HN50B17 IDLER is a steel idler sprocket designed for Browning chain size 50 drives, with a 3.72-inch outside diameter. It functions as a tensioning and guiding component in Browning chain-drive systems, helping to maintain proper chain tension and alignment along the drive path. Built to endure typical industrial workloads, the HN50B17 carries Browning branding and the model designation HN50B17, indicating its compatibility with Browning 50-series chain assemblies. The 3.72" outside diameter provides the engagement footprint for the chain path and contributes to stable, even wear across the chain, sprockets, and related components. This part is commonly used in industrial machinery and equipment that rely on Browning chain-driven power transmission, conveying energy through the chain while maintaining proper tension and preventing slack.
