- 製品の特徴
- Internal Wedge Structure: Delivers powerful clamping force with compact and stable structure.
- Anti-collision Pad Design: TPU buffer pad at piston front end effectively reduces metal collision noise during gripper release.
- High Positioning Accuracy: Dowel holes at the bottom ensure high mounting precision and consistent re-installation positioning.
- Multiple Mounting Options: Supports rear tapped hole mounting and front through-hole mounting for diverse application layouts.
- Premium Material Configuration: Aluminum alloy for body and piston, stainless steel for jaws and piston rod, NBR O-rings for sealing.
- Operation Precautions
- Low circuit pressure may cause clamping force attenuation and workpiece dropping. Anti-drop devices must be installed mandatorily.
- Avoid operation under excessive external force or impact to prevent internal component damage.
- Prevent dropping, collision and surface damage during installation and fixation.
- Clean pipeline debris before piping to avoid foreign matter entering the cylinder.
- Take anti-freezing measures in low-temperature environments to prevent moisture freezing inside the system.
- 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.
- 選定基準
Recommended safety factor: a=4. The clamping force shall be 10 に 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.

- Special Working Condition Adaptation:
High-speed & high-cycle operation: Prioritize SMC (最大 180 c.p.m.) or FESTO (最大 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 (例えば, Airtac HFCQ series, SMC -M9B series).
- Procurement Suggestions for Replacement Models
- 直接交換: For non-high-precision mounting and moderate performance requirements, direct replacement according to the table is available, reducing overall cost by 30%~50%.
- 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 (例えば, SMC D-M9 series, FESTO SME series).
- Cost Optimization Solution:
Bulk procurement: 国内ブランド (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: 取付寸法, 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。
