The SKF PHG V-belt, section A, is a classic-profile belt used to transmit power between grooved pulleys in industrial machinery. It provides a secure grip in the pulley groove, keeps motion transfer smooth, and requires little maintenance. You will find it on pumps, fans, compressors, machine tools, and other driven equipment. MR Industrial Accessories supplies this belt through its power transmission line.
Reading the code is straightforward. PHG identifies SKF's classic V-belt range. The letter A is the cross section. The number that follows is the nominal length in inches, so PHG A100 is a section A belt measuring 100 inches. When an X and a digit appear at the end, the belt is multi-rib: the digit tells you how many ribs are built into the one piece.
These belts handle a broad range of duties across the United States and Latin America. Typical installations include centrifugal pumps, fans, air compressors, machine tools, conveyors, and process equipment in food, textile, chemical, and metallurgical plants. The classic profile suits drives that need a steady transmission ratio and some ability to absorb vibration. You will also see them on agricultural equipment and low- to medium-power drives.
Selection starts with the power to be transmitted, the rotation speed, and the pulley diameter. Check pulley alignment and tension carefully, since either being off shortens belt life. Belts are not lubricated, but the pulleys should stay clean and free of burrs. In oily or dusty areas, guards or covers help protect the belt. Fit the belt without forcing it over the pulley, and use the right tools so the cord is not damaged.
Because V-belts are identified by section and length, a PHG A100 can be replaced by another brand's belt with the same section A and 100-inch length, as long as it meets the dimensional tolerances. Compounds and construction can vary between manufacturers, so confirm compatibility with the original equipment. MR Industrial Accessories can suggest equivalents from recognized brands.

Frequently asked questions
- How do I identify the section of an SKF PHG V-belt?
- The section appears as a letter in the designation, such as the A in PHG A100. That letter sets the profile width and height. To confirm the section of a belt already in service, check the code stamped on the back or measure the top width.
- What does the X3 or X4 suffix mean on a PHG belt?
- The X followed by a number means the belt is multi-rib, with several ribs in a single piece. X3 is 3 ribs and X4 is 4 ribs. This allows more power to be transmitted in a smaller space.
- Are SKF PHG section A belts compatible with pulleys from other brands?
- Yes, provided the pulleys have grooves with the section A profile and standardized dimensions. Compatibility depends on the pulley's dimensional standard and the belt. Verify the pulley profile before replacing the belt.
