B54 V-Belt

Traditional V-Belts come in cross-sections like Z, A, B, C, and D, with over 500 available lengths. For industrial applications, V-belts are classified by RMA standards (e.g., A52) — where the letter indicates the cross-section and the number is the nominal internal length in inches — and by DIN standards (e.g., 13x1320Li), with the first number representing width in mm and the second the internal length in mm.
