❓ Frequently Asked Questions | Solid PU Closed Round Belt FAQ
What equipment is this PU round belt suitable for?
This closed polyurethane round belt works together with matching U-groove pulleys. Widely used on packaging machines, printing equipment, textile machinery, tile processing lines, food transport conveyors, woodworking machines and various DIY model transmission systems.
How do I choose the correct circumference size?
Measure the actual center distance between two pulleys, calculate the required closed loop circumference. Select the corresponding diameter to match your pulley groove dimension. Ensure appropriate pre-tension after installation to avoid excessive elongation or slipping.
Can this PU round belt be cut and reconnected?
The belt can be hot-melt welded. However, original factory closed loop offers more stable performance. If you need custom length, please confirm size before purchase.
What is the maximum continuous operating temperature?
Recommended continuous working temperature is between -30℃ and 60℃. Avoid long-term usage above 60℃, otherwise premature aging and deformation may occur.
What is the advantage of plasticizer-free solid PU material?
No plasticizer precipitation, harder to deform, less elongation, longer service life, avoids contaminating transported goods, ideal for food and printing industry applications.
