ConveyXonicTM Poly-V® Conveyor Belts

Dura-Belt is a master distributor for Hutchinson ConveyXonic High Tension Poly-V® powered roller belts (also called PolyVee, multi-rib belts,V-ribbed belts, and Micro-V® belts). ConveyXonic long-life, low maintenance, truly endless, elastic, stretchy nylon reinforced, rubber belts can greatly extend the capabilities of powered roller (MDR) conveyors:

1. While our round and flat urethane belts require less energy and therefore less powerful and lower cost motorized drive rollers than PolyVee belts, ConveyXonic Poly-V belts can move heavier boxes at higher speeds on longer zones and stop much quicker.

2. ConveyXonic belts can move extremely heavy loads, including pallets weighing up to 3400 lbs (1542 kg), or boxes weighing up to 250 lbs per roller (113 kg/roller). Driving force can be easily magnified by adding more ribs.

3. PolyVee belts move loads smoothly over a wider speed range -- up to 800 feet per minute (4 m/s).

4. Poly-V belts allow one motorized roller to power up to 20 rollers with high torque, i.e., very little reduction in rpm or torque. This means that each slave roller can provide nearly the same driving force as the motorized roller.

5. While our new HEHT round belts can also move up to 20 rollers per zone, ConveyXonic Poly-V belts can move low weight boxes up to 50 rollers per zone -- 25 on each side of a high power MDR.)

6. Nylon reinforcements in ConveyXonic belts are slightly elastic. This allows them to stretch 3% to 5.5% so that the belts will perform well over the typical center distance tolerance range (+/- 1/16”) found on most conveyor frames.

7. Plastic PolyVee endcaps (also called inserts) are available for 1.9" and 50mm conveyor rollers. They reduce standard roller ratings to 70 lbs per roller (31 kg/roller), which limits box weight to approximately 760 lbs (300 kg), but that is still more than 3 times greater driving capacity than is provided by elastic round belts. Dura-Belt's high quality Poly-V endcaps are very cost competitive.

8. Pulley grooves on adjacent rollers must be aligned within one degree. Otherwise, the belts will abrade. Alignment washers take up the slack between frames, forcing standard spring-loaded rollers into alignment. Rollers that are screwed to the frame (like those provided by Interroll) do not need alignment washers.

10. Two and three ribbed belts will work on curves down to a minimum radius of 31.5" (800 mm) or about 5 degrees between rollers, although minor belt dusting occurs.

9. Poly-V belts are excellent replacements for chains on pallet conveyors. Ribbed roller endcaps (also called hubs) made from steel take the place of sprockets. In many applications poly-v belts work better, as they usually last considerably longer and eliminate the noise, oil and dirt associated with steel chains. Click here to see our poly-v endcaps for 2.5" rollers.

10. Designed to work even in dusty environments, the tips of the belt’s Poly-v ribs are truncated so they do not extend to the bottom of the pulley’s grooves. This provides an open space where dust can accumulate. The belt’s nylon reinforcements produce enough tension to force dust into this slot. As the pulley rotates, the dust usually falls out of the pulley. Nevertheless, if there is any doubt about the operating environment, we recommend testing a section of the conveyor in the environment where it will be used.

11. The force required to install Poly-V (multi-rib, V-ribbed, Micro-V) belts is about 25 lbs (11kg) per rib. The best way to install them is to use the roller as a lever. Simply remove the roller and place it through the belt on top of the adjacent roller so that the belt is around both rollers in the appropriate poly-v endcap grooves. Then insert the roller shaft on the poly-v endcap side into the frame hole, which will be used as the fulcrum. Now grasp the other end of the roller as if it were a lever and push/pull it until its shaft pops into the opposite frame hole. Repeat this process for each roller.

12. Temperature range for standard ConveyXonic belts
is -30°C to 80°C (-22°F to 176°F).

13. ConveyXonic belts are antistatic in compliance
with ISO 1813.

14. Water, alcohol, and alkali (pH 10) resistant. Not recommended for acid, oil or grease environments.

TKF Belt Guard Safety shield

(yellow) covers Poly-V belts


Warning:  Protective guards or safety shields should be installed over poly-v belts wherever people may come in contact with them. These V-ribbed belts do not stretch enough to accommodate objects caught underneath, and the pulley's sharp ribs provide nip points that could severely damage fingers or pull hair, jewelry or clothing caught in them. Low horsepower (24 volt) motors do not mitigate the need for shields, as the force per unit area on a rib's edge is very large. Moreover, the momentum of heavy boxes would make the rollers difficult to stop by hand. Shields can be purchased from TKF, Inc, who makes yellow protective guards as shown above. King Conveyor makes low cost guard tabs that attach to the frame and fit tightly under the belt, preventing fingers from sliding under the belt.

Minimum Pulley diameter is measured from the outside edge of the belt on the pulley. It depends upon the speed and drive force required.   If less than 1" (25mm), contact Dura-Belt for a determination.
