For chain drives that face washdowns or damp conditions, SKF offers the PHS SS line: stainless steel sprockets sized for 25 pitch roller chains. MR Industrial Accessories supplies these sprockets to maintenance and purchasing teams throughout the United States and Latin America, as part of its power transmission range.

The part number tells you most of what you need. Take PHS 25-1B9SS: PHS is the SKF series for roller chain sprockets; 25 is the chain pitch expressed in eighths of an inch, so 25/8 equals 1/4 in; 1B means single strand, one row of teeth; 9 is the tooth count; and SS confirms stainless steel construction. The same logic applies across the line, for example PHS 25-1B10SS or PHS 25-1B16SS, where only the tooth count changes. Reading the code this way speeds up identification.

These sprockets suit low- to medium-power drives where corrosion resistance matters. Food plants that wash equipment often, pharmaceutical operations that need clean rooms, and beverage lines exposed to constant moisture are typical users. You will also find them on packaging machinery, conveyors and process equipment. Stainless steel handles frequent cleaning without the rust issues of standard carbon steel.

When selecting a sprocket, start with the tooth count. Fewer teeth raise chain speed and accelerate wear; more teeth give a smoother drive but increase the outside diameter. Confirm the pitch matches your chain (25 in this case) and check that the bore and keyway fit the shaft. During installation, align the sprocket and chain carefully to prevent premature wear. Keep the chain properly tensioned and lubricated. Sprockets do not use seals, but keeping the surrounding area clean helps.

For cross-reference, SKF PHS sprockets can be swapped with equivalents from other makers that use the same pitch and tooth count, as long as hub and bore dimensions match. Interchangeability hinges on tolerances and tooth profile. On critical drives, have a specialist confirm the replacement before you install it.
