Myth:  All V-Belts are same

Facts: The V-belts come in numerous variation, each of the v-belts offer various and unique characters that make them suitable for different ad various applications. However, not all V-belts are the same,  some will perform better at getting you closer to your end goal. The various types of v-belts available include: cogged, raw-edge, wrapped and banded v-belts – which incorporate two or more v-belts joined together to make a single belt which provides extra strength due to all the belts being exactly the same length. 

Myth: To replace a belt, you have to cut the belt and roll a new belt

Facts:  Rolling a belt over a sheave briefly increases the tension in the belt, often to a level that is too high for the cord structure to maintain integrity. So, belt installed this way only can last few weeks. In this situation, plan for shorter belt life.

Myth:  All high – force drive pulleys are same

Facts: Each belt drive is different and specific belt tooth profiles. Professionals know about the belt profiles which they use. The chloroprene belt body is heat and ozone resistant with a high tooth shear resistance. Fiberglass tensile cord provides high dimensional stability and maximum flexibility. The nylon tooth cover provides durability, wears resistance and increased power capacity.

Myth:  Cam belts with polyamide cord are better                        

Fact:  The purpose of cords is only to carry the force and maintain the belt dimension. Cam belts with steel, polyamide, fiberglass works the same and are equally effective.  However, that re-tensioning intervals are typically the same for belts with Kevlar and with other tensile members, because belt tension changes more rapidly for Kevlar tensile members (even though the amount of change is smaller).

Myth: Cam Belts don’t stretch

Facts: Cam Belts also stretches like V-belts but as compared to V-belts , Cam belt’s stretch are insignificant. The cord structure in Cam belts is designed not to stretch, because they must maintain dimensional accuracy. The timing belt will stretch, if not break, within 10k miles of hard abuse. That is due to the fact of the high strain those cams put on. That is why they recommend changing it at certain intervals.
