Gear couplings are mechanical devices designed to transmit torque between two shafts that are not collinear. They consist of two hubs with external teeth and a sleeve with internal teeth, allowing for slight misalignments while maintaining efficient power transmission. These couplings are widely used in heavy-duty industrial applications due to their high torque capacity, durability, and ability to accommodate angular, parallel, and axial misalignments. Gear couplings are essential in industries such as manufacturing, mining, and energy, where reliable machinery performance is critical.

Gear couplings are versatile and used in various sectors. Common applications include:
What is the primary function of a gear coupling?
Gear couplings are used to connect two shafts for torque transmission while accommodating misalignments and reducing shock loads.
How do I select the right gear coupling for my application?
Consider factors such as torque requirements, shaft size, misalignment type and degree, operational speed, and environmental conditions. Refer to our product table for specifications.
Can gear couplings be used in high-speed applications?
Yes, our gear couplings are rated for speeds up to 10,000 RPM, but always check the specific speed rating for your model to ensure compatibility.
What maintenance is required for gear couplings?
Lubricated types require periodic greasing or oiling, while maintenance-free versions use self-lubricating materials. Inspect regularly for wear and tear.
Are gear couplings suitable for corrosive environments?
Yes, we offer couplings made from stainless steel or with protective coatings to resist corrosion in harsh conditions.
What is the difference between gear couplings and other types like flexible couplings?
Gear couplings handle higher torque and misalignment compared to many flexible couplings, which are often used for lighter loads and simpler applications.
How do I install a gear coupling properly?
Ensure shafts are clean and aligned within tolerance. Slide the hubs onto the shafts, secure with keys or set screws, and attach the sleeve. Follow manufacturer guidelines for torque settings.
What are the signs of gear coupling failure?
Common indicators include unusual noise, vibration, overheating, lubricant leakage, or visible wear on teeth. Regular inspections can prevent sudden failures.
Can I customize a gear coupling for specific needs?
Absolutely. We provide custom options for bore size, material, and lubrication type to meet unique application requirements.
Do gear couplings require balancing?
For high-speed applications, dynamic balancing is recommended to minimize vibration and ensure smooth operation, especially in precision machinery.
