Stroke length and contact length of micro components
The contact length depends on the position of the guide bush, ball bushing and guide rod relative to each other at the end position of the linear movement, distinguishing 2 different modes according to type:
| 1. Open guide bushing STROKE Series and MINI STROKE Series The steel ball bushing length L2 is greater than or equal to the guide bushing length L1 Maximum stroke linear motion: S=2*(L2-L1) |
 |
| 2. Closed (integrated) guide bushing CLOSED series The length of the guide bushing L1 is greater than the length of the ball bushing L2 The steel ball bushing is a special integrated design fixed in the guide bushing. Maximum stroke linear motion: S=2*(L1-L2) |

Actual measurement analysis of micro components
Actual Measurement Analysis - Operational Efficiency
The micro-components in the measuring equipment are shown in Table 2-4-1. Under normal use conditions, excluding major equipment damage and human negligence,
their lifespan is approximately between 2 and 3 years without interruption. It can operate up to 30 to 50 million times, and its operating efficiency is 3 times higher than other brands.
The advantages of choosing HEADWAY micro components are shown in Figure 2-4-2, which include high precision, low wear rate, and greatly extended service life.
