High-Torque Forged Gears for Offshore Jack-Up Rigs
High-torque forged gears are engineered to deliver exceptional strength, durability, and reliability under the most demanding offshore conditions. Manufactured from premium alloy steels such as 42CrMo4 and 18CrNiMo7-6, these gears undergo precision forging, heat treatment, and rigorous quality inspections to ensure superior fatigue resistance and long service life.
Key Features:
Exceptional load-bearing capacity and high torque transmission efficiency.
Optimized material properties for superior wear resistance and toughness.
Precision forging and machining for tight dimensional accuracy and smooth operation.
Heat-treated for enhanced hardness and resistance to harsh marine environments.
Applications:
These forged gears are widely used in offshore jack-up rigs, particularly in elevating and positioning systems such as rack and pinion drives, gearboxes, and lifting mechanisms. Their robustness ensures safe and efficient operations in oil & gas exploration, drilling platforms, and other heavy-duty offshore equipment.

| Product Name | High-Torque Forged Gears for Offshore Jack-Up Rigs |
| Material Grades | - 42CrMo4, 18CrNiMo7-6, 30CrNiMo8 alloy steels for high strength and toughness - Materials selected for corrosion resistance, fatigue strength, and high torque demands in marine environments |
| Forging Equipment | - Hydraulic Hammers: 5T, 8T, 12T - Open die and closed die forging capabilities for large-diameter, heavy-duty gears used in offshore lifting systems |
| Manufacturing Process | Forging → Normalizing/Quenching & Tempering → Rough Machining → Gear Hobbing/Shaping → Heat Treatment (Carburizing/Induction Hardening) → Final Machining → Dimensional & Non-Destructive Inspection |
| Forging Ratio | ≥ 3.5 — Provides refined grain structure, excellent strength-to-weight ratio, and superior fatigue resistance under cyclic offshore loads |
| Heat Treatment Options | - Carburizing + Quenching + Tempering for hardened gear teeth and tough gear core - Induction hardening for selective reinforcement of load-bearing areas - Optional surface treatments to improve saltwater corrosion resistance |
| Applications | - Rack and pinion drive gears for jack-up rig elevating systems - High-torque gear transmission for offshore drilling platforms - Lifting and positioning systems in marine heavy equipment |
| Process Compliance | Manufactured in line with API, ABS, or customer-specific offshore engineering standards, ensuring reliability in extreme marine environments |
| Delivery Conditions | - Heat treated, supplied as rough-machined blanks or fully finished gears - Optional surface hardening and anti-corrosion coatings for offshore conditions |
| Testing & Inspection | - Chemical Composition Analysis - Mechanical Properties: Yield Strength, Tensile Strength, Impact Toughness, Hardness - Non-Destructive Testing: UT, MT, Surface Crack Detection - Dimensional Accuracy and Gear Profile Inspection |
Process flow:
Raw material verification → material unloading → dimensional & surface inspection → controlled preheating → forging operation → heat treatment process → in-process inspection → rough machining → non-destructive examination → final inspection → protective packaging → shipment.
