SKF Sprocket, 25.4mm Width - PHS 40-1BH19

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.

Features and Benefits:

• 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.

Applications

• 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.

What bore arrangement allows final fitting to shafts?

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

Which material influences its wear characteristics?

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

How does the hub dimension affect assembly mounting?

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

What internal clearance is available for shaft modifications?

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