"Within 0.2 degrees. Well within the 'K' limit for perpendicularity."
The designation identifies a specific combination of precision levels: iso 2768-mk
"Can we re-machine them?" Elias asked.
Part 1 defines four tolerance classes: , m (medium) , c (coarse) , and v (very coarse) . The "m" class is the most common industry default, balancing manufacturing cost with functional precision. Nominal Length (mm) Tolerance (mm) over 3 to 6 over 6 to 30 over 30 to 120 over 120 to 400 over 400 to 1000 Table data sourced from typical ISO 2768-1 Medium charts . 2. ISO 2768-2: Geometrical Tolerances (Class K) "Within 0
The result? Misaligned shafts, excess friction, and a full recall. and a full recall.
