The forged and machined design offers precise alignment, dust sealing, and resistance to harsh operating environments. Customizable bore and diameter options ensure perfect compatibility with a wide range of crane and heavy machinery models, supporting torque requirements up to 45,000 Nm and speeds reaching 4500 RPM.

Built for Longevity and Low Maintenance

Manufactured with a focus on durability, the gear teeth are hardened to HRC 40-55, and each unit undergoes rigorous heat treatment, grinding, and polishing for longevity. With proper periodic inspection and lubrication, users can expect a life expectancy of over 10 years. The metallic silver finish not only provides an attractive look but also offers enhanced protection against wear and corrosion.

FAQ's of Gear Coupling for Crane:

Q: How does the gear coupling accommodate misalignment in crane applications?

A: Our gear coupling can handle up to 1.5 angular and 0.5 mm parallel misalignment. The flexible gear tooth design allows for compensating slight misalignments between connected shafts, making installation easier and reducing mechanical stress during crane operation.

Q: What is the recommended maintenance process for this gear coupling?

A: Periodic maintenance involves inspecting the coupling during scheduled crane servicing and replenishing the grease lubricant as needed. Regular checks for dust seal integrity and alignment help ensure optimal performance and extend service life.

Q: Where can this gear coupling be installed, and is it compatible with most crane models?

A: This coupling is compatible with a wide range of crane types and heavy machinery, fitting most drive shafts thanks to customizable inner bores (20 mm to 200 mm) and various outer diameter options. It meets AGMA, IS, and DIN standards, ensuring seamless integration with international equipment.

Q: What are the main benefits of choosing this gear coupling for cranes?

A: Benefits include high torque transmission capacity (up to 45,000 Nm), resistance to shock and alternating loads, minimal maintenance requirements, robust dust-proof sealing, and a long operational lifespan exceeding 10 years with proper care.

Q: How does the material and surface treatment enhance the coupling's durability?

A: Manufactured from alloy or carbon steel, each unit is heat-treated and precision ground with a polished finish. This combination improves wear resistance, minimizes friction, and provides enhanced protection against harsh environmental conditions.

Q: What temperature range and environmental conditions can the coupling withstand?

A: The coupling operates efficiently in temperatures spanning from -20C to +120C, making it suitable for both indoor and outdoor crane applications across varying climates and working environments.
