For manufacturers on Alibaba.com, positioning CNC machining capabilities correctly in product listings directly impacts buyer inquiry rates and conversion.

ISO 2768 Tolerance Standards: The Foundation of Precision Manufacturing

ISO 2768 is the international standard for general tolerances in manufacturing, widely adopted for CNC machined components. Understanding this standard is crucial for Southeast Asian exporters communicating with global buyers on Alibaba.com.

The standard consists of two parts:

ISO 2768-1: Covers linear and angular dimensions with four tolerance classes:

f (Fine): ±0.05mm for 0.5-3mm dimensions, ±0.1mm for 3-6mm
m (Medium): ±0.1mm for 0.5-3mm, ±0.2mm for 3-6mm - most common for general manufacturing
c (Coarse): ±0.2mm for 0.5-3mm, ±0.5mm for 3-6mm
v (Very Coarse): ±0.5mm and above for non-critical components

ISO 2768-2: Defines geometrical tolerances (flatness, straightness, perpendicularity, symmetry, run-out) with three classes:

H (High precision): Tightest geometrical controls
K (Medium precision): Standard for most industrial applications
L (Low precision): For non-critical features

ISO 2768-1 Linear Dimension Tolerance Classes

Nominal Length Range (mm)	Fine (f)	Medium (m)	Coarse (c)	Very Coarse (v)
0.5 to 3	±0.05mm	±0.1mm	±0.2mm	±0.5mm
3 to 6	±0.05mm	±0.1mm	±0.3mm	±1.0mm
6 to 30	±0.1mm	±0.2mm	±0.5mm	±2.0mm
30 to 120	±0.15mm	±0.3mm	±0.8mm	±4.0mm
120 to 400	±0.2mm	±0.5mm	±1.2mm	±6.0mm
400 to 1000	±0.3mm	±0.8mm	±2.0mm	±10.0mm

For material handling equipment like hand carts and trolleys, ISO 2768-mK (medium linear tolerances with K-class geometrical tolerances) is the most commonly specified standard. This provides adequate precision for wheel axle fits, frame assembly interfaces, and load-bearing surfaces without incurring unnecessary manufacturing costs.

Critical components requiring higher precision (such as bearing seats or precision shafts) may specify ISO 2768-fH or even tighter ISO 286 fit classes (IT6/IT7) for interference or transition fits.

ISO 2768 eliminates the need to specify individual tolerances for every dimension on engineering drawings. Instead, manufacturers apply the standard tolerance class globally, with exceptions noted for critical features requiring tighter control ^[1].
