Belt Description
390 L 075 PU BANDO (390 L 075 U) is a timing belt designed for highly precise and stable transmission in low to medium power ranges, with high torque and at both low and high speeds.
The belts are made from a special BANCOLLAN polyurethane compound reinforced with steel tension member. They allow long-term, maintenance-free operation in miniature and very small transmissions, meeting demands for high transmission capacity, precision, and cleanliness.
Belt Construction
- Polyurethane teeth
- Steel or aramid tension member
- Polyurethane backing
Belt Fields of Use
Bando BANCOLLAN polyurethane timing belts provide reliable solutions for very low, low, and medium power ranges across various applications.
They are typically used in machines and devices ranging from the smallest, miniature equipment such as printers, copiers, 3D printers, plotters, cameras, ATMs, optical devices, kitchen appliances, hand tools, industrial manipulators, and robots, among many others.
Their use is particularly advantageous in applications where oil from technological processes, transmissions, or bearings may affect belt properties (e.g., machining tools or gearboxes), in applications that generate ozone during operation (e.g., optical devices and copiers), or in applications requiring clean power transmission. The belts are suitable for laboratory and medical devices, as well as food processing and packaging machines.
Belt Characteristics
- Highly precise synchronous operation and minimal backlash, even in reverse drives
- High dimensional and shape stability
- High efficiency (up to 98%)
- Temperature resistance from −30 °C to +70 °C
- Maintenance-free
- Abrasion resistance = very clean operation (no small particles or dust released like with rubber belts)
- Resistance to oils, greases, acids, and alkalis
- Resistance to ozone
