Any equipment maintenance worker will know the headaches of needing a belt for any older machinery. There will be any number of issues when buying a replacement. The importance of a synchronous timing belt will be seen by all that have to run any needed work equipment. Going online or a new brand of belt can lead to getting something that is too small or too big. No company needs the downtime from the time it takes to find the correct size.
People who do not usually do maintenance are not always aware of the problems with getting parts, especially belts. Companies stop making belts for their own equipment when there have been too many years since a particular model stopped being made. A synchronous timing belt is needed for many pieces of equipment. If it breaks, the equipment will not work. If a company known for making the right size discontinues making the belt, then a new company will be needed. The older the equipment, the harder it is to find the right size. The right brand will help this from happening.
Word Of Mouth
The best way to find the right parts is by word of mouth. The internet has allowed for maintenance people a way to communicate with each other. Forums for people is not a place to create competitive environments. The communication will allow a company to know the best places to find a synchronous timing belt without worrying about lost time and profits.
