What is Pitch?
Pitch is the length in toothed belts from top of a tooth to top of the side tooth. This length can be metric or British unit (inch).
Where is the width and length of belt?
Basically its narrow part is its width; long part is its length or perimeter.
How should I measure the length of belt?
Length of all belts does not be measured in the same way. For example while the length of toothed belt is calculated as (Pitch*Number of Teeth), the length of V belts is calculated by measuring girt from back of the belt. You can contact us for that.
How should I measure the width of belt?
You can easily measure the width of belt with the help of a caliper, however in case it may be abrasions from edges at belts worked very long time the most reliable method is to measure the width of part of pulley and gears where the belt sit.

There are so many different colors of polyurethane belts; does it affect power and quality of belt?
Polyurethane is a material which can be produced in desired color with pigments. The color (pigment) of product does not definitely affect the quality of product and carrying capacity. The quality of production and polyurethane material affects the quality of product.
Do colored belts paint materials in my system?
Pigments have chemically fused into structure of material and this color does not depart from the material definitely. Consequently you can use colored belts in your system.
I used colored belts but materials in my system are painted?
Such a case can only be in case starting to abrasion of belts from edges and at the same time this indicates that your system is not operating properly. If your belt narrows from edges in time while operating, pulley axis can be wrong and this wrong turns into many problems till engine burning.
What is the advantage of using colored belt?
If a problem occurs while colored PU belts are operating, eye notices the difference more quickly because of being colored of the belt. Eye can fall into illusions at white or transparent belts.
Why do we need for different tooth types?
Different tooth types also bring along different strength and hold specifications. Consequently, it can be necessary to be used of belts have different tooth structure for different systems.
At machine design according to what should I choose the tooth type?
In such a case basically there is need to look strength and hold specifications of different typed belts from product catalog. If strength and hold are not very important for you, choosing of tooth form is totally relevant to corporate culture. There won’t be any difference in your using metric or British units.
How much is hauling power of belt affected at making endless of open ended belts?
In PU timing belts, mostly cord inside carries the power. Due to that cords in the belt cannot be glued together in case of making endless of open ended belts, only PU material will carry the power. And this causes declines at maximum power resistances.
I cannot decide which attaching methods of open ended belts I will choose?
Attaching methods show differences according to place of use. You can consult us relevant to this subject.
Why confused Flex (Self Endless) belts with attached belts?
Due to attaching operation is made by thermally boiling, if not be looked carefully, the place where attachment was made cannot be found and you can cause wrong product use.
How do I distinguish the attached belts from the nonattached belts?
Find the point where cord starts at its edge from the back of your belt and start to follow inside the belt. If there is any disorder or interruption, or if you constantly revolve within the same circle and cannot get out from other side of the belt, your belt is attached. Because cords in endless belts are rolled in spiral order, and cords in open ended belts are rolled in longitudinal order.
There is coat on my belt, I cannot distinguish whether my belt is attached or not?
Turn as the part where teeth of your belt will be above. Start to follow its teeth. Usually after heat sealing operation it leaves a very slight roughening at sealing part. It can be difficult to notice that, you can contact us in such a case.

Where stainless steel cord belts are used?
In heavy humid environments it is faced with cases where belts rust in long times. However, these cases are valid for very unusual systems. You can consult us before deciding for use stainless steel cord.
What carries power in belt if there is breaking at cords in attached endless belts?
It is true that at PU belts the cord inside carries the power however the idea of which at attached belts steel wires do not carry power is not true. If the system is operating at points that are too close to breaking powers, tensile forces can concentrate in its joints and if this tensile cannot be carried by PU material, the belt starts to break.
I am using attached PU V belt and at its joints breaks frequently occur, what should I do?
If you have trouble at joints, its mean that you cannot probably catch the heat value of product which is required to be attached. You should purchase special equipment for a healthier bonding (attaching) operation. You can contact us for this.
