135 - VA/VE/VB

135 Series Rollers with Poly-V Pulleys: High Torque, Fast Speeds, and Low Noise for Efficient Conveyor Systems

Versions VA, VE and VB of the 135 rollers are constructed to operate with Poly-V flexible belts. They have all the standard characteristics of the 135 series, but have a pulley inserted with tight interference directly into the end of the steel tube, which is further swaged during assembly. They are available with just one tube size: Ø 50 x 1.5 mm. 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 +80°C. Lower minimum temperatures are admissible, subject to verification of the conditions of use. Packages can be moved at a speed of up to 2 m/s, while maintaining extremely low noise levels.

Catalog Unit Handling Roller (EN|IT)

Optional

High friction sleeves

Where it is necessary to increase friction between the rollers and the handled unit loads the employment of these sleeves are particularly effective. They are made with transparent Polyurethane 75 Sh.A with longitudinal grooves and are supplied separately only for rollers with tube Ø 50.

Optional

PVC covered rollers

Although not special, information on this design is given. The rough or zinc plated steel tube “N” or “Z and J” rollers with “D” values as per table, can be covered with a soft, elastic and smooth surface (hardness 73 ShA) grey colour (RAL 9006) PVC (Polyvinylchloride) plastic tube, particularly resistant to chemical agents. It is normally used to protect the roller surfaces and mostly to avoid scratching painted, enamelled, smooth, etc. load, and in some cases to increase friction. The PVC lagging is simply fitted on the tube with excellent coupling thanks to elastic tightening. Application temperatures ranging from -10°C to +50°C.
