Installation
Tightening Torques
| Fastener | Tightening Torque |
|---|---|
| Main plate to robot flange (M6×12) | Per dedicated flange instructions |
| Finger attachment bolt (M4×0.7) | 1.35 to 1.65 N·m |
| Protective cover bolt (M3×0.5) | Per protective cover instructions |
| Body tapped holes (M5×0.8) | 2.7 to 3.3 N·m, max screw-in depth 10 mm |
| Body through-holes (M4×0.7) | 1.35 to 1.65 N·m |
Attachment Mounting — 3-Finger Specific
| Step | Action |
|---|---|
| 1 | Mount the attachment using M4×0.7 bolts at 1.35 to 1.65 N·m. |
| 2 | Position the attachment from the reference plane of the finger and the mounting face. The 3-finger design self-centers round workpieces — ensure all 3 attachment faces are at equal radial distance from the axis. |
| 3 | Do not drop or bump the gripper when mounting — slight deformation causes inaccuracy or malfunction. |
| Inertial force caution: The 3-finger design uses a finite orbit type guide. When the robot generates inertial forces during movement or rotation, operate the fingers to full stroke to reset the guide. Failure to do so causes accuracy degradation over time. |
Air Supply Requirements
| Requirement | Detail |
|---|---|
| Filtration | Install air filter upstream of valve. Filtration degree: 5 µm or finer. |
| Moisture | Install air dryer or water separator upstream. Drain condensate regularly. |
| Air Quality | Clean, dry compressed air only. No chemicals, synthetic oils, salt, or corrosive gases. |
| Max Pressure | 0.6 MPa maximum — lower than RMHF2/RMHZ2. Do not exceed. |
| Lubrication | Non-lube — no lubrication required. If system uses lubrication, use turbine oil Class 1 (ISO VG32, no additive). Once applied, must be continued. |

Gripping Force Selection Guide
| Condition | Recommended Gripping Force Margin |
|---|---|
| Standard cobot operation (≤1,000 mm/s², ≤250 mm/s), µ = 0.2 | At least 5× workpiece weight |
| Standard cobot operation, µ = 0.1 (smooth surfaces) | At least 10× workpiece weight |
| High acceleration or impact loads | Increase margin beyond 5× |
| 3-finger gripping of round parts — all 3 fingers in contact | Follow SMC 5–10× guideline; the 3-finger contact distribution means total grip force exceeds single-finger spec |
| Gripping point note: For the RMHS3, the gripping point L is measured differently from 2-finger grippers — it is the radial distance from the finger pivot to the contact point with the workpiece. Keep L within the range shown in the gripping force graphs for your operating pressure. Gripping point range: 0 to 50 mm. Exceeding this range adversely affects product life. |

Application Examples
| Industry | Application | Why the RMHS3 |
|---|---|---|
| Life Sciences / Lab Automation | Test Tube & Vial Transfer | 3-finger design self-centers tubes and vials of varying diameters without tool changes. Used in automated sampling, capping, and centrifuge loading applications on collaborative robot platforms. |
| Automotive | Round Bar Stock & Shaft Handling | High internal gripping force (130 N per finger) securely holds shafts, pins, and round bar stock for lathe loading and grinding machine tending. 3-finger grip resists axial pull-off during transfer. |
| Food & Beverage | Bottle & Container Handling | Picks bottles, cans, and jars from conveyors for inspection, labeling, and case packing. The normally-closed valve option (C) retains grip on power loss during emergency stops. |
| Electronics / Hardware | Fastener & Threaded Insert Handling | Grips hex bolts, standoffs, and threaded inserts by their hex faces or shanks for precision placement into fixtures. 3-finger centering reduces placement error without vision correction. |
| Pharmaceutical | Syringe & Cartridge Assembly | Handles cylindrical syringe bodies and cartridges for filling and capping operations. Clean-room compatible with protective cover removed. Non-lube design avoids contamination risk. |
| Machine Tending | CNC Lathe Loading — Round Parts | Loads and unloads turned round parts from CNC lathes. Internal grip (expanding into bore) allows positive engagement with hollow workpieces during high-speed transfer cycles. |
Frequently Asked Questions
| What is the SMC RMHS3 used for? | |
| The RMHS3 is designed for axial gripping of cylindrical workpieces — test tubes, vials, bottles, round bar stock, fasteners, and any part with a circular or hex cross-section. The 3-finger design self-centers round parts without requiring precise pre-positioning, reducing dependency on upstream fixturing or vision systems for simple pick-and-place tasks. | |
| What is the difference between the RMHS3 and the RMHF2? | |
| The RMHS3 has 3 fingers, 8 mm stroke (diameter), and 118/130 N gripping force — optimized for cylindrical parts. The RMHF2 has 2 fingers, 64 mm stroke, and 90 N force — optimized for format flexibility and wide workpiece range. Max pressure is 0.6 MPa for the RMHS3 vs 0.7 MPa for the RMHF2. The RMHS3 does not offer an analog position sensor; the RMHF2 does (for UR, FANUC, DENSO WAVE). | |
| Does the RMHS3 work with Universal Robots? | |
| Yes. Robot code 011P (PNP) supports UR3e, UR5e, UR10e, and UR16e. All three tool changer types are supported. Connector cable: RMH-A00-11-A. Note: unlike the RMHF2, there is no analog (D-MP) sensor option for the RMHS3. | |
| Does the RMHS3 work with FANUC CRX cobots? | |
| Yes. Robot code 051P (PNP) supports CRX-5iA, CRX-10iA(L), CRX-20iA, and CRX-30iA. All three tool changer types supported. Connector cable: RMH-A00-11-A. | |
| What is the operating pressure range? | |
| 0.1 to 0.6 MPa — note the 0.6 MPa maximum, which is lower than the RMHF2 and RMHZ2 (both 0.7 MPa). The auto type tool changer requires 0.4 to 0.7 MPa. Gripping force spec (118 N external, 130 N internal) is measured at 0.5 MPa with gripping point L = 30 mm. | |
| Does the RMHS3 have an analog position sensor option? | |
| No. The RMHS3 only supports NPN (N) and PNP (P) auto switches. There is no switch code A or D-MP sensor option. If analog stroke position feedback is needed, the RMHF2 with switch code A is the appropriate product (compatible with Universal Robots, FANUC, and DENSO WAVE). | |
| What gripping force does the RMHS3 deliver? | |
| 118 N external and 130 N internal gripping force per finger, measured at 0.5 MPa with gripping point L = 30 mm. With all 3 fingers in contact, the total grip force applied to a cylindrical workpiece is significantly higher than a 2-finger gripper of equivalent per-finger spec. SMC recommends gripping force at least 5 to 10 times the workpiece weight. | |
| Does the RMHS3 work with KUKA cobots? | |
| Yes, with constraints. Robot code 061P supports the KUKA LBR-iiwa with the I/O Pneumatic media flange only. Max temperature 40°C. Power supply tolerance: 24 VDC −15%/+20%. Auto type tool changer not supported. Connector cable: RMH-A00-11-B. | |
| Is plug-in software available for the RMHS3? | |
| Yes. URCap for Universal Robots, Plug and Play Kit for YASKAWA, TMComponent for OMRON/Techman, CRX Plug-in for FANUC, and Library for DENSO WAVE. These allow gripper programming from the robot teach pendant without custom code. | |
| Can I mount multiple RMHS3 grippers on one robot? | |
| Yes. SMC RMMA Series Multi Hand Adapter supports up to 3 grippers simultaneously. Mounting angles: 90°, 120°, or 180° (two 90° adapters). ISO 9409-1-50-4-M6 compliant. | |
| What is the warranty? | |
| 1 year in service or 1.5 years from delivery, whichever comes first. Warranty applies to the product independently and does not cover consequential damage to other equipment. |
