Core Advantages
Drop-In Compatibility: Matches standard SEW dimension footprints for seamless field replacement without modifying existing machine frameworks.
High Efficiency & Energy Savings: Premium helical gear design paired with IE3/IE4 motors significantly reduces long-term operational energy costs.
Quiet Operation: Precision gear grinding and optimized tooth contact patterns ensure noise levels well below industrial limits (under 68 dB).
Global Export Readiness: Full compliance with CE, UL, and RoHS standards ensures smooth cross-border customs clearance and global site installation.
Industrial Applications
Heavy-duty belt, chain, and roller conveyors in logistics and mining.
Automated storage systems, transfer cars, hoist drives, and feeders.
Palletizers, wrapping equipment, and high-speed rotary tables.
Industrial agitators, mixers, sorting systems, and automated production lines.
Internal Construction
Helical Gear Train: High-grade alloy steel (20CrMnTi) carburized and heat-treated to HRC 58–62 for high fatigue strength and quiet operation.
Precision Housings: High-rigidity cast iron housings ensure gear axis alignment under heavy torsional loads.
Bearings & Seals: Heavy-duty tapered roller or deep groove ball bearings with NBR/FKM skeleton oil seals to prevent leakage.
Synthetic / Mineral Lubrication: Factory-filled or pre-configured based on ambient operating temperature and mounting orientation (M1–M6).
Mounting Configurations
Foot Mounting (B3)
Ideal for rigid base-plate structures and direct inline power transmission via couplings or chain drives.
Flange Mounting (B5 / B14)
Designed for close-coupling directly to machine sidewalls, agitation tanks, or custom driven equipment.
Electrical Configurations
Motors are custom-configured to match target country electrical standards and specific operating environments:
Standard Voltages: 220V, 380V, 400V, 415V, 440V, 460V, 660V (50 Hz or 60 Hz).
Protection & Insulation: IP55 / IP65 enclosures with Class F insulation (Class H available).
Brake Integration: DC or AC spring-applied fail-safe electromagnetic brakes with manual release levers.
Auxiliary Attachments: Forced cooling blowers for VFD-driven variable speed applications, incremental encoders, and PTC/PT100 thermistors.
Quality Assurance
Quality control protocols are applied at every stage of production:
Gear Accuracy Testing: Fully automated inspection centers verify gear profile, pitch deviation, and lead error.
CMM Dimensional Checks: Coordinate Measuring Machines confirm housing tolerances, bore concentricity, and shaft alignment.
Assembly & Noise Testing: Every unit undergoes no-load running tests to monitor sound levels (dB), vibration, and seal integrity.
Pre-Shipment Verification: Final inspection verifies paint thickness, shaft runout, nameplate data, and customer specifications.

Technical FAQ
Q: Can your G Series gearboxes directly replace my broken SEW unit?
A: Yes. The GR series shares identical mounting centers, shaft diameters, and keyways with SEW R series gearboxes (GR89 directly matches R87).
Q: Can you provide 2D or 3D CAD files before ordering?
A: Yes. STEP, IGES, and DWG drawings are provided immediately upon model confirmation to help engineers verify space constraints.
Q: Are custom shaft diameters and special flange dimensions supported?
A: Yes. Special shaft lengths, keyway modifications, and custom mounting flanges can be manufactured based on customer engineering drawings.
Q: What is the standard lead time for OEM orders?
A: Standard configurations ship in 10–15 business days. Bulk OEM orders or custom modifications are scheduled according to project milestone agreements.
