How to Choose OPTIBELT Belts: Types, Applications and How to Get a Quote

Classic OPTIBELT V-belts transmit power between pulleys in industrial machines. They are used in compressors, pumps, fans, and material handling equipment. Their trapezoidal profile provides good grip on standard grooved pulleys. They are a common choice when replacing a worn belt or assembling new equipment.

To identify them, look at the code engraved on the back of the belt. The letter indicates the profile and the number indicates the length. It is also advisable to measure the top width and section height. If the brand is erased, these measurements can help find the equivalent.

When requesting a quote, send the complete code or the belt measurements. A common mistake is confusing the profile: an A belt does not fit properly in a B profile pulley. Also check the condition of the pulleys before mounting the new belt. We commercialize classic OPTIBELT V-belts and provide quotes by code or measurement.

Narrow OPTIBELT V-belts have higher transmission capacity than classic ones in the same pulley width. They are used in machine tools, agitators, mills, and equipment where space is limited. Common profiles are XPZ, XPA, XPB, and XPC, each with different width and height. They allow more compact designs without losing performance.

On the part, the code usually includes the profile and length. Read it with good light and clean the belt first, as dust and grease can easily cover the letters. If the code is not readable, measure the top width and section height to determine the profile. The outside length can also be measured with a flexible tape.

To get a quote, send the complete code or the section and length measurements. Avoid ordering a narrow belt as if it were classic: they are not interchangeable. Check that the pulleys have the correct groove for the profile. We distribute narrow OPTIBELT V-belts and indicate the alternative according to your equipment.

OPTIBELT timing or synchronous belts transmit motion without slipping, maintaining synchronization between shafts. They are used in printing machines, robotics, positioners, and dosing equipment. They have teeth that mesh with toothed pulleys, so they do not slip. They are ideal when precision in the transmission ratio is needed.

The code of a timing belt indicates the pitch, width, and number of teeth. There are also profiles such as T5, T10, AT5, or AT10. If you do not have the code, count the teeth and measure the pitch between them.

When quoting, send the complete code or the pitch, width, and number of teeth data. A frequent mistake is confusing the tooth profile: HTD is not the same as T or AT. Verify that the pulley has the same pitch and profile. We commercialize OPTIBELT timing belts and provide quotes by code or measurements.

OPTIBELT Poly-V or micro-V belts have longitudinal ribs on the inner face. They are used in household appliances, office machines, fans, and equipment with small diameter pulleys. They allow power transmission with little space and high flexibility. They are common in applications where a flat belt is not enough.

On the part, the code indicates the length, profile, and number of ribs. Write down all three data as they appear, without rounding, because one rib more or less changes the part. The total width and pitch can also be measured. If the belt is very worn, the marking is sometimes lost and measurement is necessary.

To get a quote, send the complete code or the profile and number of ribs. Do not confuse a Poly-V with a flat belt: they have different pulleys. Check that all ribs on the pulley are in good condition. We distribute OPTIBELT Poly-V belts and indicate the correct option for your machine.

Flat transmission belts are used in machines with flat pulleys or drums. They appear in conveyor lines, textile machines, printing presses, and old equipment. They transmit power by friction on the flat surface. They are flexible and allow large distances between shafts.

The code of a flat belt may indicate the width and length. Sometimes they are custom-made according to the equipment. If there is no code, measure the width and outside length with the belt untensioned. The thickness and material of the friction face also matter.

When quoting, send the width, length, and thickness measurements, or the code if it has one. A common mistake is ordering a flat belt without specifying the type of splice. Check if the belt is endless or open. We quote the flat belt according to your measurements.

OPTIBELT also offers pulleys for its belts, with different types of bushings. They are used in complete drives where the entire assembly is replaced.

To identify a pulley, look at the number of grooves, the pitch diameter, and the type of bushing. For example, a pulley for a B belt with 2 grooves and a tapered bushing is ordered by those characteristics. If you do not have a catalog, measure the outside diameter and groove width.

When quoting pulleys, send the part code or the data on grooves, diameter, and bushing. Avoid ordering a pulley without knowing the type of belt it uses. Check that the bushing is compatible with the shaft. We distribute OPTIBELT pulleys and help you select the correct model.

To quote any OPTIBELT product, send the complete code that appears on the part. If you do not have the code, send the main measurements: profile, length, width, number of teeth or ribs. A photo of the belt or pulley helps identify the model. If possible, add a photo of the machine and the motor plate, which provide context about the drive. At MR we work with the brand and provide quotes promptly.

You can write to us via WhatsApp or email with the product data. If you have a belt from another brand, indicate the code and we will find the OPTIBELT equivalent. You do not need to know the exact name: measurements are enough.

Remember that we are in Buenos Aires, Argentina. We commercialize and distribute OPTIBELT products. Send your inquiry with the code, measurements, or a photo of the part. We will respond promptly with the quote.
