Heavy Duty 3VX630 Molded Notch Belt For V Belt Drives, 3VX Section, Three Eighths Inch Width, Twenty One Sixty Fourths Inch Height, Sixty Three Inch Outside Circumference, EPDM Weather Resistant, Notched Underside For Small Sheaves, Machined Edge For
✔️ EPDM weather/solvent resistance, notches fit small sheaves, edge
This heavy-duty V-belt uses EPDM rubber for long-life in outdoor and harsh environments. The notched underside provides flexibility to fit smaller diameter pulleys while maintaining strength and traction. The belt edge is machined for smooth contact with the sheave grooves, reducing slip and wear. Suitable for use in industrial power transmission where space and horsepower are critical.
✅ 3/8 in width (9.525 mm), 21/64 in height (8.33 mm), 63 in outer circumference (1600 mm)
✅ EPDM rubber resists weather, oils, water, and some solvents
✅ Notches molded on underside for small-diameter sheaves
✅ Cords bonded to belt body for equal load distribution and reduced bending stress
✅ Belt edge machined for traction and reduced wear, -65 to +250 °F operation
