Abrasion Cycles and Travel Distance: Keep Stroke Length in the Report

A cycle count does not fully describe a reciprocating abrasion exposure. The stroke length and definition of a cycle determine the associated travel distance.

Updated · NANOLAB Knowledge

The key distinction

Reports should preserve movement, load, contact material and endpoint together. Comparing counts alone can make a shorter-path test appear equivalent to a longer-path test without supporting evidence.

Practical checks

  1. Confirm whether a cycle includes one stroke or a complete return.
  2. Record the stroke length and number of cycles.
  3. Retain the other method parameters in the comparison.

Example

Arithmetic example: if a complete cycle travels out and back over a 50-millimetre stroke, its travel is 100 millimetres. One thousand such cycles represent 100 metres of travel under that definition.

Scope and limits

Travel distance alone still does not establish equivalent wear. Do not convert laboratory exposure into years or customer wash cycles without a justified correlation.
