SKF PHG timing belts with 3M profile are toothed drive elements that mesh with pulleys of the same pitch, achieving a constant speed ratio with no slippage. They are used when shafts need to be synchronized, an exact angular position maintained, or force transmitted with low noise and no tension maintenance. MR Accesorios Industriales carries this line as official brand product for industrial and automation applications.

The designation PHG …M-S… reads as follows: PHG identifies the SKF timing belt line; the number before the M indicates the pitch length in millimeters; 3M is the profile and the pitch (3 mm); and the suffix S with the final number defines the belt width. For example, PHG 81-3M-S60 is a belt with 81 mm pitch length, 3M profile and 60 hundredths of an inch in width, while PHG 141-3M-S200 combines 141 mm pitch with a greater width. Always check the complete part number before ordering.

These belts are used in drives where synchronization is critical: machine tool shafts, printing heads, packaging equipment, dosing systems, robotics and automation. In Argentina you will find them in food, textile, plastics and wood production lines, where repeatability and low maintenance are required. They are also used in pumps, compressors and fans that require constant speed and cannot tolerate slippage.

To select correctly, cross-check the pitch length, profile and width with the corresponding pulley. The 3M profile requires 3 mm pitch pulleys and the width must match the groove. During installation, align the pulleys precisely, do not force the belt over the teeth and check the tension according to the equipment manual. Low tension accelerates wear; excessive tension damages bearings and shafts. Keep the drive clean and free of oils that degrade the compound.

As for equivalents, timing belts are identified by profile, pitch and length, and different brands offer interchangeability if those three data points and the width match. A similar part number is not enough: you have to compare the complete designation and the tooth type. If you have doubts, send us the original part number and the pulley dimensions, and we will help you find the equivalent without making up part numbers.

To request a quote, send the complete belt part number on WhatsApp, for example PHG 117-3M-S160, or the pitch, profile and width measurements. At MR Accesorios Industriales we advise you so that you order the right belt and avoid downtime from a rushed choice. We can also check the pulley and the general condition of the drive if you send us the data.
