For the product page, I recommend keeping this section shorter than the SF version, because the current S..SZ37-100AD1-6 technical material mainly confirms the shaft-input arrangements rather than a complete accessory catalogue.
Premium alloy steel (20CrMnTi / 40Cr) forgings undergo strict normalizing and ultrasonic flaw detection to eliminate internal stress, optimize grain structure, and ensure superior core impact resistance.
Multi-axis CNC lathes complete high-precision turning of reference datums and end faces. High-speed CNC gear hobbing and shaping machines precisely form the initial tooth profile with strict geometric allowances.
Processed in multi-purpose atmosphere-controlled furnace lines. Surface carburizing and quenching achieve a wear-resistant surface hardness of HRC 58–62, while preserving tough, shock-absorbing cores.
Advanced CNC profile gear grinding machines eliminate heat-treatment micro-distortions. Tooth flanks are precisely modified with crowning to achieve DIN Class 5–6 accuracy, ensuring whisper-quiet running.
Gearbox housings are machined on CNC horizontal machining centers for micron-level bore concentricity. Assembled in a clean workshop with top-tier bearings (SKF/NSK/C&U) and dual-lip oil seals to guarantee zero oil leakage.
Every unit undergoes 100% full inspection: gear measurement center (CMM), dynamic running test (vibration, noise, temperature rise) and sealing test before multi-layer anti-rust film and solid plywood case packaging.
High-precision gear grinding delivers tooth surface roughness as low as Ra 0.4, with tight meshing, low vibration and noise for smoother equipment operation.
Premium materials matched with precise heat treatment ensure wear-resistant tooth surfaces and impact-resistant core, cutting maintenance and replacement costs.
Custom solutions for high-speed heavy load, corrosion resistance and food-grade scenarios, eliminating trial-and-error costs in product selection.
Scaled production supports tiered pricing for bulk orders with consistent quality; full-process control guarantees stable lead time and complete after-sales support.
Internal VCI vacuum anti-rust packaging combined with seaworthy, non-fumigation plywood crates to guarantee zero corrosion during long ocean transit.
Supporting Sea Freight, Air Cargo, and Railway Express (FOB, CIF, DDP/DDU) with real-time tracking for punctual delivery.
Full clearance support including Certificate of Origin (CO/Form E), CE certificates, and factory dynamic test reports.
100% free replacement or repair for any manufacturing-related defects under standard operating conditions within 12 months.
Professional technical team provides 2-hour response for model selection, installation guidance, and troubleshooting.
Sufficient inventory of standardized modular parts (gears, shafts, seals, bearings) ensuring rapid worldwide dispatch.
Yes. Our modular gearboxes (R, F, K, S series and planetary units) are designed to standard international mounting dimensions. They can achieve 1:1 direct interchangeability in mounting hole positions, shaft diameters, input flanges, and gear ratios without modifying your existing machinery.
To help our engineering team calculate the ideal model, please provide: input motor power (kW/HP), input/output speed (RPM) or gear ratio, required output torque (Nm), mounting position (horizontal/vertical), and the specific application or working environment.
For standard modular models (R/F/K/S series and cycloidal gearboxes), lead time is typically 7–15 days. For customized units with special ratios, shafts, or special flanges, lead time is usually 20–30 days. Emergency spare parts are dispatched within 48 hours.
All gearboxes utilize precision-machined CNC housings for micro-level bore concentricity, premium dual-lip skeleton oil seals, and top-tier bearings (SKF/NSK/C&U). Every unit undergoes a 100% dynamic running test (vibration, noise, temperature rise) and sealing test before export packing.
Our MOQ is 1 unit (sample order supported). All products come with a 12-month comprehensive warranty. Each shipment can be provided with full documentation, including dynamic test records, material certificates, CMM gear inspection reports, and CE/ISO compliance certificates.
