Your Professional PM Belt Manufacturer
PM belts are industrial poly V belts that can transmit power in narrow spaces. They combine the advantages of V belts and flat belts and are suitable for use in situations where space is limited but high power is required.
ZQDrive PM belts are widely used in automotive engines and various industrial machinery transmissions. PM belts have the advantages of long service life, heat resistance, oil resistance, wear resistance, high transmission efficiency, smooth operation, and strong load-bearing capacity. They are one of the most important types of transmission belts in industrial transmission.

PM Belt Meets the High Power Needs of Your Equipment
PM belt features a multi-rib design with a large contact area, enabling power transmission efficiency of up to 98% to meet the demands of high power and high speed transmission. The number of ribs affects the load-bearing capacity of the PM belt. The more ribs the belt has, the greater the load it can bear, thereby effectively improving the belt’s load-bearing capacity.
The efficient transmission performance of ZQDrive PM belts reduces energy loss during equipment operation, minimizes noise and vibration, ensuring long-term stable operation of your equipment.
Understand the M Section Design of Your PM Belt
The structure of the ZQDrive PM belt includes:
- Pitch: The pitch of the PM belt is 9.4 mm.
- Rib: Responsible for contacting the pulley groove, usually made of wear-resistant rubber (such as CR or EPDM), providing friction and transmission stability.
- Tensile member: Provides high tensile strength and flexibility to the belt.
- Top cover: Protect the tensile member from wear and environmental influences, further improving the structural stability of the PM belt.
- Adhesive rubber: Bond the rib to the tensile member to prevent separation between layers.
PM Belt Your Best Choice for High Power Applications
ZQDrive PM belts are high-performance drive belts that are widely used in high-power industrial applications such as large conveyors and agricultural equipment, and also play a key role in the following areas:
- Industrial equipment: compressors, pumps, paper manufacturing applications, crushers, machine tools, fans, conveyors, etc.
- Fitness equipment: treadmills and other fitness equipment.
- Automotive applications: power steering systems, air conditioning compressors, generators, and other engine accessory drive systems.
- Home appliances: vacuum cleaners, dryers, and washing machines, etc.
PM belts have the following advantages over conventional v belts:
- Higher transmission efficiency: PM belts have a larger contact area and more uniform friction, with transmission efficiency typically reaching 98% .
- Better flexibility: PM belts can bypass smaller diameter pulleys, easily achieving complex serpentine drive systems and improving belt flexibility.
- Even load distribution: Multi-rib design ensures even load distribution on the PM belt, enabling it to withstand higher loads while reducing wear and extending belt life.
- Low noise: PM belts reduce vibration and impact during operation, lowering noise levels and ensuring more stable operation.
The operating temperature range of PM belts is usually determined based on the material and specifications, generally ranging from -25°C to +100°C.
Whether the PM belt needs to be replaced depends mainly on whether it has insufficient tension causing slippage, aging and cracking of the belt surface, severe wear of the ribs, or abnormal vibration and noise.
If any of the above conditions occur, it indicates that the belt performance has declined. To ensure the normal operation of the transmission system, the PM belt should be replaced with a new one in a timely manner.
Yes, ZQDrive will refer to your equipment model, transmission power, and other parameters for fine-tuned customization. We offer PM belts in a variety of materials, lengths, widths, rib counts, and thicknesses to meet the needs of different equipment.
