What Is a PU Round Belt?
A PU round belt is a belt of circular cross-section made from thermoplastic polyurethane. Round belting is flexible and weldable, so it can be joined on site into a truly endless loop of any length, and it runs smoothly on small grooved pulleys. PU round belts are used on small drives and conveying systems such as printing, textile, food and packaging equipment, where a tidy, quiet and easily replaced belt is needed.
Because we manufacture in our own plant, we can advise on the right compound, cord and tooth profile for your machine before you order, and back it up with sample belts for your own testing.
Key Advantages of Our PU Round Belt
Every belt is engineered, moulded and inspected in house, so the advantages below are backed by real production data rather than marketing language.
Weldable to Any Length
Round belting is joined on site into a truly endless loop, so length is never a problem.
Smooth on Small Pulleys
The round profile bends easily around small grooved pulleys at high speed.
Chemical & Water Resistant
PU resists oils, greases and water, staying clean and grippy in damp plants.
Abrasion Resistant
A tough PU surface extends service life on continuous drives and conveying.
Many Colours & Hardness
Green, yellow, orange, red and translucent, in 70A to 98A hardness.
Cut to Length
Supplied as open lengths for welding or pre-welded endless loops to your size.

PU Round Belt Frequently Asked Questions
Quick answers to the questions our customers ask most often about pu round belt.
Can a PU round belt be joined into an endless loop?
Yes. Round PU belting is weldable, so we join it into a truly endless loop of any length, and the welded joint is strong enough for demanding drives.
What diameters and colours do you supply?
We supply round PU belts from 2 mm to 30 mm diameter in green, yellow, orange, red and translucent, in 70A to 98A hardness.
Which hardness should I choose?
Softer grades (around 70-85A) grip better on light drives, while harder grades (90-98A) resist wear and carry higher load on continuous duty. Tell us the application and we will advise.
What are PU round belts used for?
They drive and convey on small machines such as printing, textile, food and packaging equipment, where a tidy, quiet and easily replaced belt is needed.
How long does production take?
Standard PU round belts are typically ready in 7 to 10 working days after we confirm diameter, colour and length or loop size.
