PU Flat Belt
PU Flat Belt: oil-resistant polyurethane flat belts for clean, precise and long-life transmission.
A GOODLY PU flat belt combines a tough thermoplastic polyurethane cover with a high-tensile fabric or cord carcass. Polyurethane resists oil, grease, water and abrasion, keeps a high and consistent friction coefficient, and releases product cleanly, so the belt runs reliably without marking. We manufacture to your exact width and length, endless or open-ended, for food handling, labelling, printing and precision drive duties.

What Is a PU Flat Belt?
A PU flat belt is a flat belt with a thermoplastic polyurethane cover and a fabric or cord carcass. The PU face resists oil, grease, water and abrasion while keeping a high, consistent coefficient of friction, so a PU flat belt transmits power reliably and releases product cleanly. It is often specified where hygiene, low noise and long service life matter, such as in food handling, labelling, light conveying and precision drive applications.
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 Flat Belt
Every belt is engineered, moulded and inspected in house, so the advantages below are backed by real production data rather than marketing language.
Oil, Grease & Water Resistant
The polyurethane face shrugs off oils and coolants that would harden or swell a plain rubber belt.
High, Stable Grip
A consistent coefficient of friction transmits power reliably and releases product without sticking.
Cut & Abrasion Resistant
A hard-wearing surface extends service life on high-friction and high-speed drives.
Hygienic & Easy to Clean
Non-marking, easy-clean surfaces suit food handling and clean production areas.
Exact Width & Length
Manufactured to your drawing so the belt needs no on-site trimming.
Consistent Batches
Cast in our own plant so the compound and thickness repeat from order to order.

Fabric Carcass
High-tensile woven plies for low stretch under load.
Cord Reinforced
Steel or Kevlar cord for higher-torque drive duties.
Food-Grade Option
Compounds suitable for food-contact and hygienic lines.

PU Flat Belt Frequently Asked Questions
Quick answers to the questions our customers ask most often about pu flat belt.
What is the advantage of a PU flat belt over a rubber one?
The polyurethane face resists oil, grease and abrasion better, keeps a higher and more consistent grip, and is cleaner and easier to wash down, which suits food and precision duties.
Is a PU flat belt food safe?
We supply food-contact urethane grades that are non-marking and easy to clean. Tell us your application and we will recommend the correct compound and documentation.
Can you make an endless PU flat belt?
Yes. We supply truly endless belts for the smoothest run, as well as open lengths with a joint kit for on-site fitting.
What widths and thicknesses are available?
We slit widths from 5 mm to 500 mm and offer thicknesses from about 0.6 mm to 6 mm. Tell us your pulley and load and we will advise.
How long does production take?
Standard PU flat belts are usually ready in 7 to 10 working days after we confirm width, length and form.
