Applications and Use
Dunlop open-flanked, cogged classic V-belts are deployed across low-power, medium-power, and heavy-duty industrial drive applications. These belts are specifically utilised where standard wrapped belts cannot meet the efficiency or bend-radius criteria of high-performance transmission layouts.
When planning drive replacements or engineering new configurations, it is critical to observe profile geometry. The cross-sectional sizes, specifically AX, BX, and CX, feature distinct widths and thicknesses that are not interchangeable. Fitting a belt into an incorrect pulley groove profile causes accelerated flank wear, increased operational slip, and premature drive failure.
Typical installations include:
Industrial Airflow
Industrial ventilation systems and air handling machinery.
Industrial Equipment
Manufacturing plant equipment, machine tools, and processing lines.
Industrial Systems
Pumping configurations, compressors, and material handling systems.
Agri-Industrial Systems
Agricultural machinery and industrial sorting plant components.

Operational Advantages of the Dunlop V-Belts
Integrating Dunlop open-flanked, cogged classic V-belts into your power transmission systems provides measurable mechanical and economic advantages:
High flexural capacity
The structural cogging provides exceptional longitudinal flexibility, reducing internal bending stress and optimising power transfer.
Enhanced energy efficiency
The flexible design requires less deformation energy during pulley articulation, delivering power-saving operation.
Superior slip resistance
The specialised open-flank (raw edge) construction maintains precise wedging friction against pulley grooves, maximizing traction even under reduced installation preload.
Extended service lifecycle
Precision manufacturing and premium materials deliver an extended operating life compared to conventional wrapped industrial belts.
Nomenclature and Identification
Industrial classic cogged V-belts are designated by a standard alphanumeric nomenclature system that defines both the structural cross-section and the length parameters. The prefix indicates the specific top width and thickness dimensions (for instance, AX denotes a 13 mm nominal width, BX denotes a 17 mm nominal width, and CX denotes a 22 mm nominal width). The numeric suffix defines the internal length of the belt measured in inches.
How to Identify Your V-Belt
- Locate the alphanumeric code: Examine the top surface of the belt to find the printed Dunlop manufacturer marking.
- Identify the profile prefix: The first two letters indicate the cross-sectional size group – AX, BX, or CX.
- Read the length code: The two-digit or three-digit numeric suffix indicates the nominal internal length of the belt measured in inches (for example, AX50 denotes an AX profile with a 50-inch nominal internal length).
- Verify via physical measurement: If the marking is illegible, measure the internal length or reference datum length to cross-reference against the mechanical tables below.
Materials and Variants
Standard Raw-Edge Cogged Belts
The standard variant consists of high-modulus internal tensile cords embedded within an open-flanked, moulded rubber compound. The raw edges maximize friction against the pulley grooves, while the precision-moulded cogs on the inner flank enable operations over exceptionally small pulley diameters.
Specialised and Alternative Variants
Kevlar/Agricultural Variants
For heavy shock-load applications or clutching drives, specialised configurations featuring Kevlar tensile cords and cotton covers are available on request to reduce elongation and stretching. These are separate from the standard raw-edge cogged range.
Specialised and Alternative Variants
Alternative Materials/Anti-Static Options
Not specified in the provided technical documentation for standard AX/BX/CX cogged belts. For compliance with specific environmental conditions or specialised electrical conductivity criteria, please route your query to our technical support division.

Technical Specifications and Dimensional Tables
The following data tables provide the external length (Aussenlänge), datum/reference length (Richtlänge), internal length in millimetres (Innenlänge mm), and internal length in inches (Innenlänge Zoll) for the Dunlop cogged classic V-belt range. Precise mechanical weights, physical mass profiles, breaking limits, baseline kilowatt capacities, and exact torque factors are not specified in the provided documentation. For comprehensive system calculation support, forward your configuration parameters to our engineering staff.
Good Practice, Storage, and Maintenance
To secure the longest operating life and prevent premature failure of your raw-edge cogged classic drive system, follow these standard industrial guidelines:
- Pulley Inspection: Prior to new belt installation, check all pulley grooves for interior wear, scores, or surface pitting. Worn groove flanks distort contact pressure and accelerate raw-edge rubber decay.
- Alignment Validation: Ensure precision parallel alignment across all drive pulleys. Misalignment induces transverse stress and uneven flank tracking.
- Tension Maintenance: Adjust installation tension in compliance with the machine documentation. While Dunlop open-flanked belts provide reliable traction under lower preloads, correct tensioning eliminates harmonic vibration risks.
- Inventory Storage: Store raw-edge cogged belts in a cool, dry, and dust-free environment away from localized heat generation, direct solar exposure, or ozone pockets to maintain structural compliance.
- Safety Instruction: Always consult original machine manufacturer guidelines for strict tension limits, protective guarding clearances, and scheduled inspection cycles.
Frequently Asked Questions (FAQ)
What is the main difference between an AX profile and a classic wrapped A profile?
The AX profile features an open-flanked, raw-edge design with moulded interior cogs. This structure provides higher longitudinal flexibility and reduced internal stress compared to wrapped ‘A’ profiles, enabling use on smaller pulley diameters.
Can I use a BX belt inside an AX pulley groove layout?
No. The AX profile has a distinct top width of 13 mm, whereas the BX profile features a width of 17 mm. Groove cross-sections are not interchangeable; installation inside incorrect pulley slots results in drive slip and destruction of the belt flanks.
What do the numeric values in the suffix designate?
The numbers define the nominal internal length of the belt measured in inches. For example, a BX24 belt has an internal length parameter of 24 inches.
Are these belts resistant to industrial machinery oils?
The manufacturer specifies standard resistance to heat and oils for alternative lines like the agricultural variations. For specific raw-edge rubber exposure thresholds regarding chemical solvents, contact our engineering help desk.
