Roller-to-roller drive systems are everywhere (from office equipment and packaging lines to industrial automation).
Getting the belt specification right matters: it affects system reliability, service intervals, and total cost. Not every application has the same demands, which is why a single belt technology rarely fits all.
With the addition of our new Molded PU Round Belt range, Movendis now offers two complementary technologies within its roller-to-roller portfolio. Each with a distinct role, together they cover a wider range of applications.
Two technologies in the portfolio
Molded PU Round Belts
- Fully molded construction — no thermowelding
- Tight tolerances: ±0.1 mm on length and diameter
- Stable friction behavior (μ 0.45 steel / 0.30 plastic)
- High abrasion and fatigue resistance
- More competitive pricing for high-volume applications
Poly-V EPJ Belts
- Multi-rib transmission design
- Higher load capacity
- Optimised for demanding drive conditions
- Suited to applications requiring greater torque transmission
How to choose the right belt
Both technologies are engineered for roller-to-roller applications, but they excel in different scenarios. The table below summarises the key considerations:
| Molded PU Round Belt | Poly-V EPJ Belt | |
|---|---|---|
| Load level | Standard loads | Higher loads |
| Drive conditions | Stable, repeatable cycles | Demanding / variable |
| Volume | Competitive at high volume | Standard commercial range |
| Construction | Single molded piece | Multi-rib profile |
| Fit for | Precision, consistency | Strength, torque transmission |
A closer look at the Movendis Molded PU Round Belts
Our new Molded PU Round Belts are manufactured as a single molded piece, eliminating the variability that can come from thermowelded joints. The result is a belt that behaves consistently across its full service life, with tight dimensional tolerances of ±0.1 mm on both length and diameter.
This precision makes integration straightforward. The belts are optimised for common center distances and are designed to fit standard roller configurations without additional adaptation.
Key performance characteristics include:
- High abrasion and fatigue resistance — suited to repeated load cycles in continuous operation
- Reliable friction behaviour — μ 0.45 on steel surfaces and μ 0.30 on plastic, supporting consistent torque transfer
- Lightly polluted environment compatibility — maintains performance in real-world operating conditions
For high-volume applications where cost-efficiency is a factor, Molded PU Round Belts offer a more competitive price point compared to cut-and-weld alternatives, without compromising on dimensional stability or service life.
Why complementary technologies matter
The expansion of the Movendis roller-to-roller portfolio is not about replacing one technology with another. It is about giving partners a broader toolkit. OEMs designing new equipment can specify the belt that best matches their performance requirements from the outset. Distributors can serve a wider range of customer needs from a single supplier relationship.
Both belt families share the same underlying commitment to dimensional precision and long service life, they simply approach different points on the performance and commercial spectrum.
