FSSM40 \u2014 304 Stainless Steel | 40mm Center Distance | IP69K | Food Grade<\/h2>\n

Engineered for automated production lines and conveyor-driven logistics, the FSSM40<\/strong> from Ever-power Australia Worm Reducer Co., Ltd.<\/strong> delivers dependable speed reduction with premium 304 stainless steel housing engineered for washdown environments. Trusted by OEMs and system integrators across 60+ countries.<\/p>\n<\/div>\n

📜 FSSM40 Product Overview<\/h2>\n

The FSSM40<\/strong> 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 automated production lines and conveyor-driven logistics. The worm gear mechanism provides inherently smooth, low-vibration operation with significantly lower noise levels than spur or helical gear alternatives \u2014 typically below 65 dB(A) at rated load.<\/p>\n

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.<\/p>\n

✅ Key Features & Benefits<\/h2>\n
\n
Precision Gear Meshing<\/strong>
Ground worm shaft with Zi tooth profile ensures optimal contact geometry, reducing wear and maximizing transmission efficiency.<\/div>\n
Compact Right-Angle Layout<\/strong>
90\u00b0 shaft arrangement saves space in tight machine envelopes compared to inline reducers of equivalent torque capacity.<\/div>\n
Wide Ratio Range<\/strong>
A single gearbox covers a broad ratio spectrum, simplifying inventory management across multiple machine designs.<\/div>\n
Robust Bearing System<\/strong>
High-quality radial ball bearings support both shafts, providing excellent load capacity and minimizing axial play.<\/div>\n<\/div>\n

📚 Selection & Sizing Guide<\/h2>\n

Proper sizing prevents premature failure. Follow this simplified procedure to confirm the FSSM40 suits your application:<\/p>\n

\n

Step 1:<\/strong> Calculate required output speed: n\u2082 = Motor Speed \/ Ratio<\/p>\n

Step 2:<\/strong> Determine required output torque from your machine design.<\/p>\n

Step 3:<\/strong> Apply service factor (fs<\/sub>) based on duty cycle, load type, and daily running hours.<\/p>\n

Step 4:<\/strong> Verify M\u2082 \u00d7 fs<\/sub> \u2264 rated torque from the specification table above.<\/p>\n

Step 5:<\/strong> Calculate motor power: P\u2081 = (M\u2082 \u00d7 fs<\/sub> \u00d7 n\u2082) \/ (9550 \u00d7 \u03b7)<\/p>\n

\"NEMA<\/p>\n

🛠 Installation & Maintenance<\/h2>\n

☑ Mount on a flat, rigid surface with all foundation bolts properly torqued. ☑ Align motor and gearbox shafts within 0.5\u00b0 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\u00b0C \u2014 if exceeded, check load, alignment, and oil condition.<\/p>\n

💧 Lubrication<\/h2>\n

Use synthetic PAG oil (ISO VG 460) for ambient temperatures 15\u201340\u00b0C, 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.<\/p>\n

❓ Frequently Asked Questions<\/h2>\n
\n
\nWhat materials are used in the gear set?<\/summary>\n
\n

The worm wheel is precision-machined from CuSn12Ni2 tin-nickel bronze for exceptional wear resistance. The worm shaft is 20CrMnTi carburized alloy steel, ground to HRC 58-62 with Zi tooth profile for optimum meshing efficiency.<\/p>\n<\/div>\n<\/details>\n

\nCan I mount this in any orientation?<\/summary>\n
\n

Yes. Multiple mounting positions are supported including horizontal foot-mount, flange-mount, and vertical configurations. Ensure the oil level and breather are appropriate for your chosen orientation.<\/p>\n<\/div>\n<\/details>\n

\nWhat is the typical service life?<\/summary>\n
\n

Under rated conditions with proper lubrication and maintenance, service life regularly exceeds 20,000 operating hours. Bronze worm wheels exhibit gradual, predictable wear patterns rather than sudden failure.<\/p>\n<\/div>\n<\/details>\n

\nHow does efficiency vary with ratio?<\/summary>\n
\n

Efficiency decreases as ratio increases. Low ratios (5-10:1) achieve 85-90%, medium ratios (20-30:1) achieve 68-82%, and high ratios (60-100:1) range from 44-60%. Select the lowest ratio that meets your speed requirement for best efficiency.<\/p>\n<\/div>\n<\/details>\n

\nCan I combine two units for higher ratios?<\/summary>\n
\n

Yes. Two units can be stacked in series for ratios up to 10,000:1. Alternatively, consider our double-reduction worm gearbox series<\/a> which integrates both stages in a single housing.<\/p>\n<\/div>\n<\/details>\n<\/div>\n
