Belt type 7MS Scrum multi-rib belts

Polyurethane banded V-belts · 60° wide angle ribs · 7MS profile

Scrum belts are polyurethane banded V-belts made up of several 60° wide angle ribs joined side by side, with a grooved back that keeps the belt flexible. They’re built for high-speed drives that need smooth, quiet running with very low vibration and high precision, such as machine tools, woodworking machines and other high-speed machinery. The 7MS profile is the multi-rib version of the 7M wide angle section. Search by the code on the old belt, such as 3-7MS-800, and use the filters to narrow it down by ribs and length.

  • Multi-rib designSeveral wide angle ribs joined into one stable belt
  • High speedBuilt for fast-running drives with smooth, quiet operation
  • Very low vibrationIdeal for precision machinery and fine finishes
  • Flexible backGrooved backing lets the belt bend round small pulleys

Choosing a 7MS Scrum belt

Reading the codeScrum codes give the number of ribs, the profile and the length. 3-7MS-800 means 3 ribs of the 7MS profile, 800mm long. Match all three from your old belt.

Count the ribsThe number of ribs must match the grooves on the pulley, or the drive it was designed for. Count the ribs on the underside of the old belt before ordering.

Wide angle pulleysScrum belts have 60° ribs and run in matching 7MS multi-groove pulleys. They won’t fit standard V-belt or poly-V ribbed belt pulleys.

Tip: Scrum belts look similar to poly-V ribbed belts, but their ribs are larger and have a much wider angle. If you’re unsure, measure the width of one rib and send us a photo of the belt end-on.
