Palm oil mill chain
Tsubakimoto Chain

Contrary to popular belief, tensile strength is not the only parameter used to judge a palm oil mill chain. In fact it is NOT even the most important parameter. A more important feature, called WEAR RESISTANCE is more critical when a palm oil mill chain is to be selected.

WHY?
Because safety factor has been taken into consideration at design stage and when a chain is selected, it means that the tensile strength of the chain meets that of the design value. So there is no necessity to use a chain with much higher tensile strength than the design value.

On the other hand, the understanding of WEAR RESISTANCE is more complex. First of all, it does not have a unit of measurement (such as KN, kgf or lbf in tensile strength). The measurement is simply chain elongation measured in terms of percentage of elongation (amount of elongation to the original chain length expressed in percentage). So the smaller percentage means a better chain used in the same period of time. Generally, a conveyor chain needs replacement when it reaches 2 % elongation. The most important measurement is therefore how long before a chain reaches its life span of 2 % elongation.
