I am reading a catalogue about mechanic product-clutch. It lists the advanced features of that type of clutch. One of the features is 'long life and low wear on machine parts'. This phrase seems ambiguous to me.
Does 'long life' refer to the product-clutch itself? Or does it refer to the advances of the clutch make the machine parts long life?
P.S. I know the context I can offer is so little, and this might be difficult to give an accurate answer. But I cannot copy the other context here because it is in PDF format, and I think other contexts are not germane to this question, such as a low maintenance, quick delivery. If you cannot help without more context, it is fine for me.
"Long life" means that the clutch will last a very long time. "Low wear" on machine parts means that the friction and stress typically experienced by the components of a clutch are minimalized on this model. An automotive clutch is engaged every time the car starts or stops, so it is often one of the first pieces of equipment to break down and need replacing.
"long life" means the parts will last a long time before breaking.
"low wear" means minimal bad effects on other parts. Usually (in American English) you hear "wear and tear" to mean how "rough" something is on something else.
Example: City streets have more wear and tear on a car than do freeways.
