Series 135/138 - Poly-V belt driven roller conveyor
Other information about the product
With the same features of driven and friction chain driven rollers with pinion sprockets series 135/138, these rollers are the namesake version for belt driven roller conveyors. These rollers feature a PVC or antistatic steel tube on request, an interchangeable Poly-V flexible belt head made of black polyamide with 9 V-grooves (pitch 2,34 mm PJ form, ISO 9981 DIN 7867) and precision 6002-2RZ ball bearings.
Standard Poly-V belts have 2 ribs, but also 3 or 4-rib belts are admitted. As proof of the high performance of this transmission system, a transfer of twice the amount as that delivered by a comparable round belt driven roller conveyor is possible even when using double ribbed elastic belts. Indeed, this standard version allows up to 20 rollers to be looped together with a central drive.
Also, high handling speeds can be achieved with driven/frictioned head flexibility. In particular, a belt driven roller conveyor with series 135 can reach a speed of up to 1,5 m/s with low noise levels. Instead, when using friction rollers series 138, a maximum speed of 0,8 m/s is recommended due to the friction system and possible unit accumulation.
