Belt Type Comparison:

Chain drives are generally ideal for high torque, low speed applications.  They are relatively easy to install and are       well suited for conveyor type applications. However, chain drives do require some sort of oil bath to run efficiently. Pretensioning is also required for chain drives.  One of the major concerns regarding chain drives is sprocket misalignment.

Roller chains tend to be very lightweight but undergo considerable elongation.  These belts are prone to wear as a result of friction between the mating of the pin and bush.  The major advantage of these belts are that they are easily installed and can transmit very high torque levels.

Silent chains are heavier than roller chains.  They tend to be very expensive but are easily installed.  These belts are preferable for applications in which noise reduction is a concern.  The belt can bear heavy loads and operate at high speeds.

V-Belts are used to transmit horsepower and reduce speed.  They are a quiet, low cost product which requires little maintenance.  These belts perform better at higher speeds but are prone to slippage and high elongation.  The v-belt is made in fixed lengths and is not ideal for long belt applications.  The belt must be installed precisely to prolong life.  V-belts are also capable of producing much higher torque than flat belts.

Generally used in conveyor type applications a flat belt will take longer to wear when compared to a V-belt.  The belt is not affected by tight bends.  When put in a wet environment slippage becomes a major concern, due to a lack of positive engagement.   The ideal flat belts are ones with a nylon core because they undergo minimal elongation and are virtually maintenance free.

Wire rope is very light weight, easily installed, and inexpensive.  Based on the material selection the belt can be designed     for high corrosion resistance.  Wire rope has the ability to support very high loads with minor amounts of elongation.  The wire rope requires periodic lubrication and is best suited for long length applications.
