Rulmeca operates a Service centre fully dedicated to the repair and assembly of Motorized Pulleys
Versions V1, V2, V3 and V4 of the 138 rollers are made to operate with flexible Poly-V belts. In terms of construction, they share all the general characteristics of the 138 series, allowing for simple changing of a range of pinions and pulleys of varying type and construction, including those from the 135 series.
The pulley is made from black polyamide with 9 V-shaped grooves 2.34 mm pitch, profile J, ISO 9981 DIN 7867. The most common fittings provide for Poly-V belt rings with 2 ribs, but the pulley also allows for versions with 3 or 4 ribs. With just 2 ribs, the Poly-V belt can transmit double the torque of round belts, usually allowing at least 20 rollers to be linked together with the motor positioned centrally.
This series is intended for use in temperatures of between -5°C and +40°C for all constructions. Lower minimum temperatures are admissible, subject to verification of the conditions of use. Packages can be moved at a speed of up to 1.5 m/s, in accordance with the loads applied, but in the case of prolonged accumulation over time, it is recommended that speeds are kept to a maximum of 0.8 m/s.
