SKF PHS TB sprockets are chain-drive sprockets designed to mount on shafts and mesh with ANSI-pitch chains. They are used in gearboxes, conveyors, machine tools and process equipment where torque must be transmitted positively and synchronously. MR Accesorios Industriales carries this line as part of its power transmission catalog, with more than 80 years of experience in the field. If you need to replace a sprocket or build a new drive, send us the part number and we will quote it.

The PHS TB line designation is read in parts. PHS identifies the SKF family of sprockets for chain. The first number, as in PHS 35-1TB18, indicates the chain pitch according to the ANSI standard: 35 corresponds to a pitch of 3/8 inch. The 1 indicates it is single strand, not double or triple. TB distinguishes the hub or finish variant, and the final number is the number of teeth: 18, 19, 20, 21, 22, 23, 24 or 25 in the examples of this series. The more teeth, the higher the peripheral speed and the lower the allowable torque for the same pitch.

These sprockets are found in belt and roller conveyors, bucket elevators, mixers, bagging machines and packaging lines. They also appear in the drives of woodworking, food and plastics machinery, where the chain provides positive synchronization and tolerates dusty or dirty environments. In Argentina they are common in food, cement, ceramic and aggregate processing plants, as well as in workshops that build or repair material handling equipment. As a wear part, replacement with the same pitch and number of teeth is key to avoid overloading the chain and the shaft bearings.

To choose correctly, check the chain pitch, the number of teeth, the shaft diameter and the hub type. Verify that the bore and keyway match the shaft, and that the alignment between sprocket and chain is true: angular or radial misalignment accelerates wear on teeth and bushings. Proper lubrication — oil or grease depending on speed and load — and correct chain tension extend the life of the assembly. If the sprocket is mounted with a taper bushing or set screw, respect the tightening torque and check axial play before start-up.

Regarding interchangeability, SKF PHS TB sprockets follow ANSI standardized dimensions for pitch and number of teeth, so they can replace other manufacturers that use the same standard. Still, before changing brands it is advisable to compare the outside diameter, hub diameter, bore and keyway position, because these dimensions vary between lines. If you have the old part number or a sample, send us the data and we will help you find the equivalent within what we carry.

MR Accesorios Industriales carries the SKF PHS TB sprocket line together with chains, pulleys, housings and bearings to build or repair complete drives. If you need a quote for a sprocket for your equipment, send us the part number by WhatsApp — for example PHS 35-1TB20 — or a photo of the part and the shaft data. We will reply with the available alternative and coordinate delivery.
