GIA0802-181.5-201-D Ball Screw: Specific Parameters and Application Uses

Ⅰ. Core Parameters (Derived from Model Interpretation + Industry Characteristics)

1. Model Composition and Core Identification

• GIA0802-181.5-201-D: Composed of G (Customized Design, parameters adjustable on demand) + I (Floating Diverter, optimizing ball circulation) + A (Round Nut with Triangular Thread, self-locking and fastening) + 0802 (Basic Specification) + 181.5 (Auxiliary Parameter) + 201 (Length Parameter) + D (Accuracy/Version Identifier).

2. Basic Specification Parameters

• Nominal Diameter: 8mm. The "08" in the model is a common industry designation, corresponding to an 8mm outer diameter of the screw, suitable for small to medium load scenarios.

• Lead: 2mm. The "02" represents the lead, meaning the nut moves 2mm axially per full rotation. It belongs to a small to medium lead, balancing precision and stability.

• Nut Structure: Round Nut with Triangular Thread (marked by "A") + Floating Diverter (I).

• Triangular Thread: Usually has a 60° thread angle (metric system), with strong self-locking performance. It can be firmly fixed without additional locking parts, making it suitable for vibrating environments.

• Floating Diverter: Optimizes the ball circulation path, reduces friction and noise, improves transmission smoothness, and extends service life.

3. Length and Auxiliary Parameters

• 201: In line with industry practices, it most likely refers to the total length or effective stroke of the screw being 201mm, adapting to the stroke requirements of medium-stroke equipment (e.g., small to medium-sized automated modules).

• 181.5: May be the nut length, thread segment length, or customized feature dimension (e.g., effective engagement length of the triangular thread). Specific values need to be confirmed based on actual customized parameters, which mainly affect installation space and fastening strength.

• D: Usually represents the accuracy class or version code. It is inferred to be a customized accuracy identifier (e.g., Class D corresponding to a specific tolerance range, or an exclusive version number customized for customers).

4. Performance Parameters (Based on Customized Characteristics)

• Accuracy Control: Due to the "G (Customized)" attribute, it can be adjusted to Class C3-C7 on demand (e.g., Class C3 for precision scenarios, Class C7 for general scenarios). The positioning error can be controlled within ±0.01mm ~ ±0.05mm/300mm.

• Axial Play: ≤0.01mm by default for a single nut, supporting customized preloading (e.g., double-nut preloading can reduce it to ≤0.005mm). The floating diverter further reduces play fluctuation.

• Rated Load: Referring to the customized enhanced design of 8mm diameter + 2mm lead, the dynamic load is approximately 1.5-2.5kN, and the static load is approximately 2.5-4.5kN (specific values can be customized according to material/heat treatment).

• Transmission Efficiency: ≥92%. The floating diverter reduces circulation loss, which is higher than the 90% efficiency of standard ball screws.

5. Customized Characteristics (Core Value of "G" Identifier)

• The specifications of the triangular thread (e.g., thread diameter, pitch), screw material (e.g., high-strength alloy steel, stainless steel), surface treatment (e.g., chrome plating for rust prevention), and end processing (e.g., with keyway, flange) can be adjusted on demand.

Ⅱ. Application Uses (Based on Structural Characteristics and Customization Advantages)

1. Customized Automated Equipment

• Typical Applications: Positioning axes of non-standard small production lines (e.g., special-shaped part assembly machines), feeding mechanisms of customized testing equipment.

• Adaptation Reasons: "G (Customized)" can match the special size requirements of the equipment; the round nut with triangular thread has strong self-locking performance, preventing loosening caused by equipment vibration; the floating diverter ensures stability during low-speed feeding (e.g., precise movement of testing lenses).

2. Transmission Systems in Vibrating Environments

• Typical Applications: Feeding adjustment mechanisms of small vibrating screens, displacement components of vehicle-mounted testing equipment.

• Adaptation Reasons: The self-locking feature of the triangular thread (A) resists loosening due to vibration, without the need for additional anti-loosening devices; the floating diverter reduces the interference of vibration on ball circulation, ensuring transmission accuracy.

3. Precision Instruments and Medical Equipment

• Typical Applications: Sample stage drive of customized spectrometers, fine-tuning mechanisms of portable medical diagnostic equipment.

• Adaptation Reasons: The customized design (G) meets the compact space requirements of instruments; the low-noise characteristic (≤55dB) of the floating diverter is suitable for medical environments; the round nut with triangular thread is easy to install and can be fastened without complex tools.

4. Outdoor or Harsh Environment Equipment

• Typical Applications: Lifting mechanisms of small outdoor monitoring equipment (e.g., meteorological sensor adjustment axes), material pushing devices in dusty environments.

• Adaptation Reasons: Stainless steel material + anti-rust treatment can be customized (G attribute) to improve corrosion resistance; the triangular thread combined with a sealed design (e.g., adding an O-ring) reduces dust/moisture intrusion; the floating diverter reduces the impact of impurities on transmission.

5. Scientific Research and Experimental Devices

• Typical Applications: Customized mechanical testing platforms in laboratories, joint transmission of small bionic robots.

• Adaptation Reasons: Customized parameters (e.g., special lead, end structure) meet the unique needs of experiments; the high dynamic response (start-up delay ≤0.05s) of the floating diverter adapts to the rapid movement of robot joints; the round nut with triangular thread is convenient for manual fine-tuning and fixing.

Ⅲ. Selection and Customization Recommendations

1. Clarify Customization Needs: If used in a vibrating environment, emphasize the anti-loosening level of the triangular thread; if used in a precision scenario, prioritize customizing Class C3/C5 accuracy.

1. Load Matching: The actual load is recommended not to exceed 40% of the rated dynamic load (customized design can improve redundancy, but overloading should be avoided).

1. Environmental Adaptation: For outdoor or humid scenarios, it is recommended to customize stainless steel material + surface coating, and optimize the nut sealing structure.
