Fit it right first time

Finding and fitting belt drives is a task that can take a bit of time, especially if you’re not 100% sure what you’re looking for. Our handy tips are designed to make it, giving you more time to focus on the projects that warrant more of your time being spent on them.

 How to identify the correct Poly-V belt

 The best way to identify the correct Poly-V belt is to look at the number of ribs and length of the belt. The supplier reference for Poly-V belts is made up of:

  • Number of ribs

  • Generic belt section – for Automotive it’s “PK”

  • External length of the belt in mm

For example – if the belt has 4 ribs, the reference will start with: 4 + PK. You need to measure the belt and if the length is 895 mm, then the supplier reference will be: 4 + PK + 895 = 4PK895

 

How to identify the correct V belt

 The best way to identify the correct V belt is to look at the width and length of the belt. Depending on the brand, the supplier reference for V belts is made up of:

  • Top width in mm

  • Generic belt section – for Automotive it’s “A”

  • External length of the belt in mm

  • Generic belt feature – for the belts with teeth it’s “C”

  • Generic belt section – for Automotive it’s “AV”

  • Top width in mm

  • External length of the belt in mm

  • Use “x” between the generic section, the width and the length

For example - if the belt size is 10mm wide and 1085mm long then the reference from, Dayco is - 10 + A + 1085 + C = 10A1085C. The reference from, Contitech is - AV x 10 x 1085 = AVX10X1085.
