Dinghan linear guides adopt Taiwan's technological standards. The ball tracks are precisely ground and the straightness error is controlled within ±0.005mm/m. The repeat positioning accuracy reaches ±0.003mm. The slider of Dinghan linear guides is designed with a four-row recirculating ball system, and the rigidity is enhanced through pre-load adjustment technology. So, how to choose the right Dinghan linear guide? Let's elaborate below.

What should be noted when choosing Dinghan linear guides?

I. Clarify Basic Technical Parameter Requirements

1. Load Capacity Assessment

Based on the maximum static and dynamic loads during equipment operation, a safety margin of 20% to 30% should be reserved. For instance, the rated dynamic loads of various series of Dinghan linear guides are different. Heavy-duty equipment should prioritize the widened slider series. Special attention should be paid to shock load conditions, and models with medium (0.05C) or heavy (0.07C) preload grades should be adopted.

2. Precision Grade Matching

Dinghan guides are classified into standard grade (±50μm/m), advanced grade (±30μm/m), and precision grade (±15μm/m). Semiconductor wafer handling equipment is recommended to use precision grade models, while ordinary logistics conveyor lines can use standard grade. It is important to note the exponential growth relationship between precision and price - the price of precision grade is usually 2 to 3 times that of standard grade.

3. Speed and Acceleration Parameters

For high-speed applications, the DN value (shaft diameter × rotational speed) should be considered. The combined linear speed of Dinghan ball screw and guide rail can reach 5m/s.




 

II. Special Operating Conditions Adaptation Solutions for Dinghan Linear Guides

1. Poor Environment Adaptation

- Damp Environment: Select stainless steel models or those with surface chrome plating treatment

- Dusty Environment: Configure double oil scraper plates + labyrinth seal dust-proof kits

- High-temperature environment: High-temperature resistant models with special lubricants

2. Vibration suppression solutions

For vibration-sensitive equipment such as CNC machines, it is recommended:

- Select the series with equal load design in four directions

- Use in conjunction with damping shock absorbers

- Control the flatness of the installation base within 0.01mm/m

3. Long stroke solutions

For strokes over 4 meters, pay attention to:

- Control the joint accuracy when using spliced guide rails

- Select materials with matching thermal expansion coefficients

- Increase the number of auxiliary support guide rails

The above is an introduction to how to choose Dinghan linear guides. As a core transmission component, the performance of linear guides directly affects the precision, stability and lifespan of equipment. Dinghan linear guides, as a well-known domestic brand, have been widely used in machine tools, semiconductors, medical instruments and other industries due to their stable product quality. Through the introduction above, we hope everyone can choose the linear guide that suits them.
