SKF PHS DSA series sprockets are chain drive components used for power transmission. They mount on shafts and engage with roller chains to transfer motion and torque in many types of machinery. As a brand that MR supplies, SKF sprockets are built to SKF standards for dependable operation in demanding industrial settings.
The part number tells you the main features. PHS is the SKF sprocket line. The next number is the chain pitch per ASA standard. The -1 means single strand, one row. DSA indicates a hub with a pilot bore. The final digits give the tooth count, such as 15, 16, or 17. For example, PHS 40-1DSA15 is a sprocket with pitch 40, single strand, and 15 teeth. Suffixes can appear for special finishes, but the basic structure stays the same in this series.
These sprockets are found in chain drives on industrial machines, conveyors, elevators, agricultural equipment, packaging lines, and motion systems in food and beverage plants. They are also common in metallurgical, cement, and agro-industrial operations where a robust, low-maintenance drive is needed. Their design adapts to different mounting arrangements and transmission ratios.
When selecting a sprocket, consider chain pitch, number of teeth, shaft diameter, and hub type. Check that the pilot bore can be machined to the required diameter and that the hub width suits your mounting. Proper alignment between sprocket and chain is essential; misalignment speeds up wear. Follow the manufacturer's lubrication instructions and check chain tension regularly. If you bore the sprocket, work to suitable tolerances to prevent eccentricity.
For equivalences, SKF PHS DSA sprockets follow ASA standards for pitch and tooth count, so they can interchange with other brands that meet those dimensions. Always confirm hub dimensions and bore diameter, as these can differ between manufacturers. If you are unsure, send us the full designation and we will help you find the right option.

Frequently asked questions
- What does the designation PHS 40-1DSA15 mean?
- PHS is the SKF sprocket line. The number 40 is the chain pitch per ASA standard. The -1 means single strand (one row). DSA is the execution with hub and pilot bore. The final 15 is the number of teeth. So it is a sprocket with pitch 40, single strand, and 15 teeth.
- How do I choose the right sprocket for my machine?
- You need the chain pitch, the number of teeth you want, the shaft diameter, and the available space. Also consider the transmission ratio and service conditions. If you have doubts, contact us with your application details and we will advise you.
- Are SKF sprockets interchangeable with other brands?
- Yes, as long as they follow the ASA standardized dimensions for pitch and number of teeth. Still, check the hub and bore dimensions because they can vary between manufacturers. For a safe replacement, compare the critical measurements before mounting.
