Description
FSSH63 — 304 Stainless Steel | 63mm Center Distance | IP69K | Food Grade
Engineered for gate operators and access-control mechanisms, the FSSH63 from Ever-power Australia Worm Reducer Co., Ltd. delivers dependable speed reduction with premium 304 stainless steel housing engineered for washdown environments. Trusted by OEMs and system integrators across 60+ countries.
📜 FSSH63 Product Overview
The FSSH63 is a precision-built worm gear speed reducer designed for reliable right-angle power transmission in demanding industrial environments. Featuring premium 304 stainless steel housing engineered for washdown environments, this unit transforms high-speed motor rotation into controlled, high-torque output suitable for gate operators and access-control mechanisms. The worm gear mechanism provides inherently smooth, low-vibration operation with significantly lower noise levels than spur or helical gear alternatives — typically below 65 dB(A) at rated load.
All gear components are manufactured under ISO 9001-certified quality management. The worm wheel is machined from wear-resistant bronze alloy, while the worm shaft undergoes carburizing and precision grinding to achieve a hardened tooth surface. This material combination ensures gradual, predictable wear characteristics rather than sudden failure, giving maintenance teams confidence in planning scheduled interventions.
✅ Key Features & Benefits
The 304 stainless steel housing with optimized fin geometry ensures efficient thermal dissipation during continuous duty cycles.
At higher ratios, the unit provides reliable self-locking — the load cannot back-drive the output, eliminating external brakes in many applications.
Input interface accepts both IEC metric and NEMA imperial motor flanges, providing worldwide sourcing flexibility.
Oil-bath lubrication, double-lip oil seals, and corrosion-resistant finishes minimize maintenance intervals and downtime costs.

📚 Selection & Sizing Guide
Proper sizing prevents premature failure. Follow this simplified procedure to confirm the FSSH63 suits your application:
Step 1: Calculate required output speed: n₂ = Motor Speed / Ratio
Step 2: Determine required output torque from your machine design.
Step 3: Apply service factor (fs) based on duty cycle, load type, and daily running hours.
Step 4: Verify M₂ × fs ≤ rated torque from the specification table above.
Step 5: Calculate motor power: P₁ = (M₂ × fs × n₂) / (9550 × η)

🛠 Installation & Maintenance
☑ Mount on a flat, rigid surface with all foundation bolts properly torqued. ☑ Align motor and gearbox shafts within 0.5° angular and 0.05 mm parallel tolerance. ☑ Fill lubricant to the oil-gauge center line before first operation. ☑ Remove the breather vent plug to allow air circulation. ☑ Perform the first oil change after 100 operating hours, then every 2,500 hours thereafter. ☑ Maximum allowable oil temperature is 95°C — if exceeded, check load, alignment, and oil condition.
💧 Lubrication
Use synthetic PAG oil (ISO VG 460) for ambient temperatures 15–40°C, or ISO VG 320 for cooler environments. Recommended brands: Shell Tivela S, Mobil Glygoyle, or Esso Spartan EP series. For food-processing applications, use NSF H1 certified food-grade lubricant only. Fill to the sight-gauge center line.
🚧 Troubleshooting
| Symptom | Cause | Action |
|---|---|---|
| 🌡 Overheating | Overload / misalignment / low oil | Reduce load; re-align; check oil level |
| 📳 Vibration | Loose bolts / worn bearings | Re-torque fasteners; replace bearings |
| 🔈 Noise | Poor mesh / insufficient oil | Inspect gears; refill lubricant |
| 💧 Leakage | Worn seals / loose drain plug | Replace seals; tighten with sealant |
❓ Frequently Asked Questions
How do I select the correct size?
Determine your required output torque and speed, apply the service factor for your duty cycle, then verify against the rated torque table. Our engineering team can assist — contact us for free sizing support.
Can this unit handle bidirectional rotation?
Yes. The gearbox operates identically in both directions with no preferred rotation. Simply reverse the motor wiring. Note that at self-locking ratios, reversal must be initiated from the input side.
What is the maximum operating temperature?
The oil temperature should not exceed 95°C. The aluminum housing provides efficient heat dissipation. If ambient temperature exceeds 40°C, derate the torque or add supplemental cooling.
How noisy is this worm gearbox?
Under rated load, noise is typically below 65 dB(A). Worm gears are inherently quieter than spur or helical gears due to their sliding contact. Synthetic lubricant further reduces noise.
Does Ever-power provide technical support?
Absolutely. Our application engineers provide free sizing calculations, CAD drawings, and motor-matching guidance. Email us your requirements for prompt assistance.
