SKF 19 Tooth Rough Stock Bore Sprocket, PHS 40-1BH19 40-1

This sprocket is a steel drive wheel designed to transfer motion within roller chain systems. It is configured with a rough-stock bore to allow customised mounting and aligns with ANSI chain standards for consistent engagement in industrial power transmission setups.

• 19 teeth provide predictable chain engagement and speed ratio.
• Compatible with 40-1 chain to ensure correct pitch matching.
• 25.4 mm width supports lateral chain stability during operation.
• Pitch diameter 12.7 mm delivers accurate sprocket-to-chain geometry.
• Hub diameter 63.5 mm offers a substantial mounting surface for hubs.
• Outside diameter 83.82 mm reduces radial runout risk in assemblies.

• Used with conveyor drive modules requiring ANSI parts.
• Suitable for industrial chain drive replacements and refurbishments.
• Ideal for machines needing a 19T sprocket for speed change.
• Can be used where a rough-stock bore requires final machining.
• Used for retrofits demanding 40-1 chain compatible components.

The component is supplied with a rough-stock bore to permit finishing operations to the EXACT shaft size.

It is manufactured from steel which provides durability under cyclic chain loading.

The 63.5 mm hub diameter increases bearing-surface contact and supports secure fixation in hub-mounted configurations.

The maximum inside diameter is 44.45 mm, defining the largest inner space before additional machining.
