5. Caracteristicile produsului
6. Internal Wedge Structure: Delivers powerful clamping force with compact and stable structure.
7. Anti-collision Pad Design: TPU buffer pad at piston front end effectively reduces metal collision noise during gripper release.
8. High Positioning Accuracy: Dowel holes at the bottom ensure high mounting precision and consistent re-installation positioning.
9. Multiple Mounting Options: Supports rear tapped hole mounting and front through-hole mounting for diverse application layouts.
10. Premium Material Configuration: Aluminum alloy for body and piston, stainless steel for jaws and piston rod, NBR O-rings for sealing.
11. Operation Precautions
12. Low circuit pressure may cause clamping force attenuation and workpiece dropping. Anti-drop devices must be installed mandatorily.
13. Avoid operation under excessive external force or impact to prevent internal component damage.
14. Prevent dropping, collision and surface damage during installation and fixation.
15. Clean pipeline debris before piping to avoid foreign matter entering the cylinder.
16. Take anti-freezing measures in low-temperature environments to prevent moisture freezing inside the system.
17. For long-term storage after disassembly, perform rust protection on surfaces, install dust plugs on air ports, and apply anti-rust oil on moving parts.
18. Referință de selecție

Recommended safety factor: a=4. The clamping force shall be 10 la 20 times greater than the workpiece weight.

Clamping Force Formula: F > mg/(n×μ)×a

(n = number of jaws, μ = friction coefficient, m = workpiece mass, g=9.8m/s²)

If friction coefficient μ＞0.2, follow the 10~20 times weight standard for clamping force selection.

Reserve a higher safety factor for high acceleration and heavy impact working conditions.

3. Key Notes for Replacement & Selecţie

3.1 Structural Difference Comparison

3.2 Selecţie & Ghid de înlocuire

1. Function Matching: The HFC series are double-acting type. La înlocuire, select the double-acting models of corresponding brands (de ex., SMC suffix `-D`, FESTO suffix `-A`).
2. Compatibilitate de montare:

Mounting hole positions, dimensions and bolt specifications may vary; please check the mounting dimension drawing before replacement.

Airtac HFC rear positioning hole: Φ26⁺⁰·⁰⁵ mm, depth 1.5mm, different from some competitor brands.

3. Performance Parameter Verification:

4. Special Working Condition Adaptation:

High-speed & high-cycle operation: Prioritize SMC (max 180 c.p.m.) or FESTO (max 150 c.p.m.); Airtac: 120 c.p.m.

High-precision positioning: All brands meet ±0.01~±0.02mm for interchangeable use.

Corrosion-resistant environment: Select stainless steel jaw models (de ex., Airtac HFCQ series, SMC -M9B series).

4. Procurement Suggestions for Replacement Models
5. Înlocuire directă: For non-high-precision mounting and moderate performance requirements, direct replacement according to the table is available, reducing overall cost by 30%~50%.
6. Fully Compatible Replacement:

For 100% dimensional matching, use the same brand series or custom mounting brackets.

If sensor interfaces differ, replace with brand-specific magnetic switches (de ex., SMC D-M9 series, FESTO SME series).

3. Cost Optimization Solution:

Bulk procurement: Branduri autohtone (Airtac, Chelic) offer higher cost performance to replace imported products.

Small-batch trial: Purchase 1~2 replacement units for mounting and performance testing before mass adoption.

Airtac HFC series and mainstream brand parallel open/close pneumatic fingers share consistent core functions and are mutually replaceable. Prioritize verifying four key parameters: dimensiuni de montaj, clamping force, stroke and port specifications to guarantee system compatibility and stability. It is recommended to refer to the official technical manuals of corresponding brands for accurate specifications before replacement。
