SMC MHF replacement fingers are precision-manufactured alternative components for worn, damaged, or discontinued original gripper fingers. MUXI Precision produces compatible MHF2 fingers based on original parts, drawings, samples, and application requirements — with customized materials, contact geometry, and surface treatments.
What Is SMC MHF Series?
SMC MHF2 is a low-profile pneumatic parallel gripper series widely used in industrial automation for pick-and-place, assembly, machine tending, and material handling applications. Its compact design — approximately one-third lower in height than comparable gripper series — makes it a popular choice for space-constrained automation cells.
The gripper fingers are the components that directly contact the workpiece. During millions of operating cycles, these contact surfaces gradually wear due to mechanical friction, repeated clamping force, contamination, and workpiece variation. When finger wear affects gripping reliability, replacement becomes necessary to maintain production stability.
MHF2 series is available in bore sizes from 8 mm to 32 mm, each with three standard stroke lengths (short, medium, long), offering flexibility across a wide range of automation applications from small electronics assembly to CNC machine tending.
Why SMC MHF Fingers Need Replacement
Common SMC MHF2 Models
Custom replacement fingers are available for the following SMC MHF2 bore sizes. Each bore size offers short, medium, and long stroke variants. Common applications are listed for reference — if your model isn't listed, send your gripper details for compatibility evaluation.
| Model | Typical Application |
|---|---|
| MHF2-8D replacement finger | Ultra-compact automation, micro electronics assembly |
| MHF2-12D replacement finger | Small parts handling, light assembly |
| MHF2-16D replacement finger | General industrial automation, pick-and-place |
| MHF2-20D replacement finger | General handling, material transfer, light CNC |
| MHF2-25D replacement finger | CNC machine tending, heavier assembly |
| MHF2-32D replacement finger | Heavy-duty handling, large part transfer |
Replacement Finger Design Considerations
Custom replacement fingers can be engineered to better match specific application requirements through three optimization dimensions.
Finger Surface Design
The contact surface geometry directly affects gripping stability and workpiece protection. Common options include:
| Contact Surface | Best For | Consideration |
|---|---|---|
| Flat finger | General flat workpieces | Simple, cost-effective |
| V-groove finger | Round / cylindrical parts | Centers round parts, prevents rolling |
| Form-fit contour finger | Complex shaped workpieces | Maximizes contact area, reduces marking |
| Soft jaw insert compatible | Surface-sensitive / finished parts | Non-marring, vibration damping |
Material Selection
| Application | Recommended Material | Key Properties |
|---|---|---|
| General handling, high-speed | 7075 Aluminum | Lightweight, good strength-to-weight |
| CNC machine tending, oily env. | 6061/7075 + hard anodizing | Wear resistance, oil-resistant surface |
| Heavy / abrasive parts | Hardened steel (4140/4340, HRC 40-55) | High wear resistance, impact strength |
| Surface-sensitive parts | Polyurethane insert / UHMW | Non-marring, vibration damping |
| Welding fixtures / hot environment | Tool steel / heat-treated alloy (4140/4340) | High-temp strength, thermal fatigue resistance |
| High-temperature environment | PEEK / engineering plastics | Thermal stability, chemical resistance |
Surface Treatment
| Treatment | Benefit |
|---|---|
| Hard anodizing (Type III) | 2-3× wear life for aluminum fingers |
| Teflon-impregnated anodizing | Non-stick surface, reduced contamination buildup |
| Nitriding / case hardening | Surface hardness increase for steel fingers |
| TiN coating | Extreme wear resistance for high-cycle applications |
OEM SMC Finger vs Engineering-Based Custom Replacement
OEM replacement remains a reliable option. However, engineering-based custom replacement provides additional flexibility when optimization, faster delivery, or legacy support is required.
| Aspect | OEM Replacement | Engineering-Based Custom Replacement |
|---|---|---|
| Availability | Depends on supplier stock | Flexible production |
| Lead time | Depends on region | Short production cycle |
| Design | Original specification | Application optimized |
| Material | Fixed options | Selectable from engineering guide |
| Legacy support | Depends on model availability | Possible from sample or drawing |
| Small batch | May be difficult | Single set to volume pricing |
