Overview
Specifications
Belt Selector
The Carlisle Super Blue Ribbon “C” section V-belt features a 7/8″ top width × 17/32″ depth cross-section and is available in both Smooth and Cogged profiles. These belts deliver exceptional performance in industrial, agricultural, and commercial drive applications across the Permian Basin and beyond.
Smooth (Wrapped) — “C” Prefix: Traditional wrapped construction with heavy-duty cover fabric. The fabric wrap provides excellent grip and quiet operation. Ideal for standard drives where smooth running and long belt life are the priority. Best for sheave diameters 9.0″ and above.
Cogged (Notched) — “CX” Prefix: Raw-edge cogged construction with precision-molded notches on the underside. Provides superior flexibility around small sheaves, cooler running temperatures, and up to 30%% greater efficiency on small-diameter pulleys compared to smooth belts. Recommended for sheave diameters under 9.0″ or variable-speed drives.

Horsepower Ratings per Belt — C-Section (7/8″ x 17/32″) at 1,750 RPM
These ratings apply to all C and CX belts. For multi-belt drives, multiply by the number of belts.
| Sheave Pitch Dia. | HP per Belt |
|---|---|
| 7.0″ | 4.37 |
| 7.5″ | 5.10 |
| 8.0″ | 5.77 |
| 8.5″ | 6.38 |
| 9.0″ | 6.93 |
| 9.5″ | 7.43 |
| 10.0″ | 7.89 |
| 10.5″ | 8.30 |

| 16.0″ | 10.78 |
| 18.0″ | 11.09 |
| 20.0″ | 11.22 |
1 HP ratings are for single C-section belt at 1,750 RPM with 180° arc of contact. For multi-belt drives, multiply by number of belts and apply arc correction factor.
2 Cogged (CX) belts provide approximately 15-20%% additional HP capacity on small sheaves due to improved flex.
3 All dimensions shown in tri-format: fractional, decimal, and metric where applicable.
Select your belt by part number. Smooth belts use the “C” prefix. Cogged belts use the “CX” prefix. Table scrolls — headers stay fixed.

1 Smooth (C) and Cogged (CX) belts are interchangeable on the same sheave — cogged versions provide better flex and efficiency on small pulleys.
2 Inside Length = belt number in inches. Outside Circumference = belt number + 2 inches. All dimensions in tri-format.
🔧 V-Belt Length Calculator
Enter your sheave diameters and center distance to calculate the correct C-belt size. We’ll recommend the closest belt from our inventory.
Formula: Belt Length = 2C + 1.57(D + d) + (D − d)² ⁄ 4C
Where C = center distance, D = large sheave pitch dia., d = small sheave pitch dia.
C-section pitch diameter ≈ sheave O.D. − 0.4″.
Tip: If the calculated size falls between two belt numbers, choose the next size up and adjust the motor mount to increase center distance for proper tension.
