Measure the center-to-center distance between your pulleys, then calculate the required belt circumference using the standard formula: 2 × C-to-C + π × (D1 + D2) / 2. These belts are typically around 815mm (≈32.1") in circumference. If you need a custom length, contact us before ordering and we can advise on available options.

Rubber drive flat belts of this type generally handle light-to-medium power transmission loads suitable for mask machines, small motors, and conveyor systems. Exact tensile strength depends on belt width and thickness — contact us to confirm specs for your specific application.

Rubber flat belts are generally resistant to moisture and mild humidity, making them suitable for indoor industrial environments. For prolonged outdoor exposure or contact with oils and chemicals, please confirm material compatibility with us before ordering.

These flat belts are designed for smooth-face pulleys. Compatible pulley width should match or slightly exceed the belt width. Pulley diameter should be appropriate for the belt thickness — in most cases, a minimum pulley diameter of 10–20× the belt thickness is recommended to avoid excessive bending stress.

Yes — these belts are listed as customizable. If you need a specific length, width, or thickness beyond the listed variant options, please contact us with your machine specs and we will advise on the best fit or arrange a custom order.

Mask machines and conveyor systems in production environments go through belts regularly due to wear and tension cycling. Buying in a 100-piece bulk pack ensures you have on-hand replacements to minimize downtime, and typically offers a lower per-unit cost compared to single purchases.

In most cases, flat belts are installed by loosening the motor mount to reduce pulley tension, slipping the belt over both pulleys, then re-tensioning the motor until the belt has minimal slack without excessive stretch. Always power off the machine before replacing belts.
