Fast assembly, as strong as a welded belt.
Since the first patent in 2014, we've been constantly improving ERO Joint® HP.
We've created new versions: with polyamide textile, with antistatic textile, with integrated drive guide, as well as a version for the food industry.
And we've also created tooling to facilitate assembly.
For this new version, we have once again optimized the axes, modified the shape of the assembly teeth, optimized the entire manufacturing process to gain in quality, created cable jumps to improve width cutting, and above all we are replacing the original cables with Zylon® (the polymer fiber with the highest tensile and bending strength).

Benefits
ERO Joint HP® replaces any welded belt with ultra-fast installation.
The Zylon version is even more efficient, more stable under heavy loads and more durable.
ERO Joint® HP is a patented mechanical splicing solution for polyurethane belts. A hinge pin with a single stainless steel rod is used to close the belt.
ERO Joint® HP is produced in sheets from 100 to 300 mm wide, cut to size and welded to the base belt.
Belts are available with steel, aramid, HF or stainless steel Cords, with all types of coating, machining and guiding system.
The admissible tractive strain and service life are similar to those of welded belts.
We can supply finished belts, as well as plates that can be welded to polyurethane belts of any brand (with the same melting parameters as the belts).
Alternatives
Spiral joints
Mechanical spiral joints are as easy to assemble as an ERO Joint® HP joint, but their mechanical strength is very low.
Pin Joint
The Pin Joint mechanical jointing system is more difficult to assemble than an ERO Joint® HP joint.
Mechanical strength is also lower than an ERO Joint® HP joint.
