Single-strand chain wheels in the SKF PHS …BH… range carry a hub and arrive with a pilot bore, so the drive transmits motion through roller chain. They suit conveyors, production machinery and other drives where the transmission has to run consistently. Fitting is straightforward and the wheels integrate easily into existing power transmission layouts.
Reading the code helps you order the right wheel. PHS marks the series: single-strand with hub. The number that follows is the chain pitch, so 25 stands for 1/4" and 35 for 3/8". A 1 confirms single strand, BH tells you the wheel has a pilot bore plus hub, and the last figure is the tooth count. PHS 25-1BH10, for instance, is a 25 pitch, single-strand wheel with pilot bore and 10 teeth. PHS 35-1BH12 and PHS 25-1BH18 follow the same pattern, differing only in pitch and teeth.
You will see these sprockets in chain drives across food processing, metallurgy, agriculture and logistics. Belt and roller conveyors, packaging equipment, lifting gear and general drive systems are typical homes for them. Plants, workshops and production lines that need synchronized, positive transmission rely on this type of wheel.
Selection comes down to four things: chain pitch, tooth count, shaft diameter and how the wheel is mounted. Check that the pilot bore leaves enough material to be machined to your shaft. Lubrication and alignment between sprocket and chain do most of the work in keeping the drive smooth, so check tooth wear and chain tension on a regular schedule.
PHS series sprockets swap with other brands built to the same pitch and tooth count. Before replacing, compare outside diameter, pitch diameter and tooth width. Standards are usually consistent, but confirming compatibility with the system in front of you is worth the minute it takes.

Frequently asked questions
- What does the BH suffix mean on SKF PHS sprockets?
- BH means the sprocket comes with a pilot bore and a hub. The bore can then be machined to the shaft diameter and fitted with a keyway or set screw, which lets the same wheel serve different mounting arrangements.
- How do I pick the number of teeth for my drive?
- Tooth count follows the transmission ratio you need and the space you have. More teeth generally mean lower speed and higher torque. Send us your details and we can work through the combination with you.
- Will SKF PHS sprockets run with chains from other brands?
- They will, provided the chain uses the same standardized pitch. Match the pitch, such as 25 or 35, and confirm the tooth width suits the chain you plan to run.
