Description
The AX51 is a heavy-duty classical cogged (notched) V-belt featuring a 1/2-inch top width, a 5/16-inch thickness, and a 53-inch outside circumference. The molded notches allow it to flex around very small pulley diameters while running cooler and more efficiently than standard wrapped belts.
Key Specifications
- Belt Series: AX Cross-Section
- Top Width: 1/2 in (13 mm)
- Thickness / Height: 5/16 in (8 mm)
- Inside Length (Pitch): 51 in (1295 mm)
- Outside Length: 53 in (1346 mm)
- Construction: Raw-edge, single-band cogged
Materials & Performance
- Tensile Cords: Premium polyester cords protect against shock loads and minimize stretch under heavy stress.
- Body Compound: Fiber-reinforced rubber engineered to maintain precise sidewall contact and resist deformation.
- Raw-Edge Sidewalls: Unwrapped edges maximize grip within the pulley grooves, eliminating slip and increasing power transfer.
- Environmental Resistance: Formulated to withstand oil contamination, heat buildup, and ozone wear.
Common Uses
- Commercial HVAC systems, exhaust fans, and air handlers
- Industrial air compressors, generators, and water pumps
- Heavy-duty shop machinery, grinders, and drill presses
