The Cutting Belt is a new type of belt that, with its unique design and superior performance, is gradually replacing traditional wrapped belts (A, B, C, SPZ, SPB, etc.). Unlike traditional wrapped belts, the cutting belt has no outer fabric layer, exposing the belt material and internal structure directly. This allows users to more intuitively observe the material and quality of the belt. It not only helps quickly identify the belt’s quality but also effectively reduces performance degradation caused by fabric detachment or wear.
The precision cutting process of the cutting belt ensures dimensional stability and transmission efficiency, enabling it to maintain excellent performance under high-load and high-speed conditions. Additionally, the cutting belt offers greater flexibility and tensile strength, demonstrating longer service life in complex environments. The simplified manufacturing process also makes the cutting belt more cost-effective.
The cutting belt undoubtedly represents a new trend in the development of belts. With its high performance and reliability, it is set to gradually become the mainstream choice in industrial, agricultural, and automotive sectors, driving the belt industry toward a new stage of development.
Cutting belts (also known as raw edge V-belts, cut edge V-belts, or precision-cut V-belts) are manufactured using a precision cutting process that produces a raw (unwrapped) edge with exact dimensional accuracy. The exposed rubber sidewalls provide superior grip in pulley grooves, and the precision-cut profile ensures tight dimensional tolerances. LYBELT cutting belts are used in:
Precision Industrial Machinery — CNC machines, precision grinders, and high-accuracy machine tools use cutting belts where dimensional consistency and minimal vibration are critical for workpiece quality.
High-Speed Equipment — Equipment operating at high rotational speeds benefits from the precise balance and consistent cross-section of cutting belts, reducing vibration and extending bearing life.
Compact Drive Systems — Equipment with small pulley diameters and tight drive layouts use cutting belts because the raw edge construction provides greater flexibility than wrapped belts, allowing tighter bend radii.
Textile Machinery — High-speed spindle drives, winding machines, and weaving equipment use cutting belts for their precision dimensions and smooth, vibration-free operation.
Automotive Auxiliary Drives — Alternator, water pump, and power steering drives on vehicles use raw edge cut belts for improved grip, higher efficiency, and better heat dissipation compared to fabric-wrapped alternatives.
Printing & Packaging Equipment — High-speed printing presses, converting machines, and packaging equipment use cutting belts for consistent speed transmission and minimal belt stretch.
Precision-Cut Dimensional Accuracy — Each cutting belt is produced through a precision cutting process that achieves tighter dimensional tolerances on V-angle, top width, and thickness than molded or wrapped belt manufacturing methods. This accuracy translates to better pulley fit, more even load distribution in matched sets, and reduced vibration.
Raw Edge Sidewalls — The exposed rubber sidewalls make direct contact with the pulley groove, providing higher friction coefficient and better grip than fabric-wrapped belts. This means less slip, higher power transmission efficiency, and more responsive drive behavior.
Enhanced Flexibility — Without the constraining effect of a fabric wrapper, cutting belts flex more freely around pulleys. This makes them suitable for drives with smaller pulleys, higher speed ratios, and more compact configurations.
Superior Heat Dissipation — The raw edge construction allows heat to dissipate more readily from the belt core, reducing operating temperature and extending service life — particularly important in enclosed or high-temperature drive environments.
Premium Compound Technology — LYBELT cutting belts are manufactured with select rubber compounds from our 130+ formulation library, engineered for the specific performance demands of raw edge belt applications including heat resistance, wear resistance, and flex fatigue life.
Custom Size Capability — Our precision cutting process accommodates both standard and custom V-belt profiles and lengths, providing flexibility for OEM applications and non-standard drive requirements.

What is a cutting belt and how is it different from a standard V-belt?
A cutting belt (raw edge V-belt) is manufactured using a precision cutting process rather than a molding and wrapping process. The result is a V-belt with exposed rubber sidewalls (raw edges) instead of a fabric covering. This provides better pulley grip, improved flexibility, tighter dimensional tolerances, and better heat dissipation compared to fabric-wrapped V-belts.
Are cutting belts the same as cogged V-belts?
Not exactly. Cogged V-belts are a specific type of raw edge belt that also features notches (cogs) on the inner surface for additional flexibility. Cutting belts refer to the broader category of precision-cut raw edge V-belts, which may or may not have a cogged inner surface. Both types feature raw edge sidewalls, but cogged belts have the additional notched profile.
What V-belt profiles are available as cutting belts?
LYBELT manufactures cutting belts in classical (A, B, C, D), narrow (SPZ, SPA, SPB, SPC), and specialty profiles. Custom cross-sections can also be produced to match specific OEM requirements. Contact us with your specific profile and length requirements.
Can cutting belts be used as a replacement for wrapped V-belts?
Yes. Cutting belts with the same cross-section designation are dimensionally compatible with standard V-belt pulleys. They are often used as a performance upgrade, offering improved efficiency, longer life, and better heat resistance. However, not all applications require the raw edge advantage — consult our engineering team if you are unsure whether a cutting belt is the right choice for your application.
What is the lead time and MOQ for cutting belts?
Lead time for standard cutting belt sizes is typically 15–30 days. Custom profiles or non-standard lengths may require slightly longer. MOQ is flexible and depends on the specific belt profile and size. Contact us with your requirements for detailed lead time and pricing information.
