These rollers have the same features as the series 135 (driven) and 138 (friction), but with a grooved head for round belts instead of pinion sprockets. This solution maintains tube concentricity. The round belt head is made of Polyamide in black colour with 2 grooves for round belt Ø 4 or 5 mm. The transmission can be completely enclosed with minimum space, without contact with the conveyed loads. This avoids possible belt misalignment and maintains driving force. The rollers have precision 6002-2RZ ball bearings. We suggest not exceeding a handling speed of 0,8 m/s, due to the transmission system In indicating the ordering code, please specify the type, the shaft diameter and execution, the tube diameter and execution, the “C” length.
