Engineering Advantages
Integrated Compact Drive: Monoblock design eliminates external couplings, pulleys, and belt alignment procedures.
High Thermal Efficiency: Aluminum die-cast housing provides rapid heat dissipation and low operating temperatures.
Synthetic Long-Life Lubrication: Factory-filled with synthetic oil, enabling all-position mounting without oil changes under normal operating conditions.
Anti-Leakage Protection: Viton/Double-lip oil seals prevent oil contamination on production lines.
Smooth & Quiet Operation: Precision-ground worm threads (<= 65 dBA) ensure vibration-free power transfer.
Industrial Applications
Conveyors & Logistics: Belt conveyors, roller tracks, sorting systems, and bucket elevators.
Packaging & Labeling Machinery: Cartoning, film wrapping, capping, and conveyor indexing.
Food & Pharmaceutical Processing: Mixers, feeders, stainless/washdown sorting lines.
Material Handling: Overhead hoists, rotary turntables, and automated storage systems.
Textile & Printing Equipment: Tensioning rollers, feed drives, and printing presses.
Mounting Configurations
Foot Mounting (B3)
Bottom-mounted casing for fixed base installations.
Output Flange Mounting (FA / FB / FC)
Direct bolting to machine side-plates.
Shaft Mounting with Torque Arm
Direct hollow-shaft mounting onto driven shaft with rubber buffer reaction arm to absorb shock loads.

Heavy-Duty Construction
Housing: Premium die-cast aluminum alloy with shot-blasting and anti-corrosion surface treatment; HT200 high-strength cast iron for maximum rigidity under heavy loads.
Worm Shaft: Made of high-grade 20CrMnTi alloy steel, precision carburized and quenched (surface hardness 56-62 HRC), with ground thread profile for high efficiency and low noise.
Worm Gear / Wheel: Centrifugally cast wear-resistant bronze alloy (CuSn12 tin-bronze ring) fused onto a ductile iron hub, ensuring high resistance to galling and wear.
Bearings & Seals: Fitted with SKF/NSK premium precision bearings and high-temperature NBR/FKM double-lip oil seals to eliminate oil leaks and prevent contaminant ingress.
Lubrication: Factory pre-filled with high-grade synthetic lubricant (ISO VG 320) for maintenance-free operation across wide temperature ranges (-20°C to +40°C).

Frequently Asked Questions
Q: How do I select the right gearbox size for my machine?
A: Determine your required output speed (rpm) and operating torque (Nm). Select the gearbox size based on rated torque output while applying a service factor suitable for your operating conditions.
Q: Can this unit replace an existing European standard gearbox?
A: Yes. Our compact worm geared motors follow standard international dimensions. Key mounting center heights, shaft sizes, and flange patterns match standard market models directly.
Q: Are 3D CAD models available for engineering design?
A: Yes. 2D CAD and 3D STEP/IGES files are available for engineering verification. Contact our support team to request files for your required model size.
Q: What is the lead time for sample and bulk orders?
A: Standard catalog configurations ship within 5 to 7 business days. Customized OEM designs or large bulk orders typically take 15 to 25 business days depending on specifications.
