Engineered for Misalignment and Performance

Half Flexible Gear Couplings allow for angular (up to 1.5) and parallel (up to 0.3mm) misalignments, making them ideal for industrial machinery where shaft alignment can fluctuate. Precision machining ensures a tight, vibration-minimizing fit, while their robust construction withstands challenging environments.

Easy Maintenance and Installation

Designed with user convenience in mind, these couplings are simple to dismantle and reassemble, streamlining routine inspection and lubrication. A grease nipple is provided for ongoing maintenance, significantly extending service life and maintaining peak efficiency in operational settings.

Customizable Solutions for Heavy-Duty Power Transmission

Available with customizable bores (20mm to 200mm) and supporting torque up to 25,000 Nm, these couplings suit a broad range of applications, including mechanical drives, motors, and pumps. Their cylindrical structure, heat treatment, and alloy steel composition guarantee high strength and longevity.

FAQs of Half Flexible Gear Couplings:

Q: How do Half Flexible Gear Couplings manage shaft misalignment in industrial setups?

A: These couplings are engineered with gear teeth and a half flexible design that permits up to 1.5 of angular and 0.3mm of parallel misalignment, effectively accommodating installation inaccuracies and operational shifts.

Q: What is the recommended lubrication process for these gear couplings?

A: Routine lubrication is essential; each coupling is fitted with a grease nipple for this purpose. Its advisable to check and replenish the grease during regular maintenance cycles to ensure efficient torque transmission and enhanced durability.

Q: When should maintenance or inspection be performed on these couplings?

A: Maintenance should be carried out during scheduled plant downtime or as outlined in the equipments maintenance protocols. Their modular design enables quick dismantling and reassembly, facilitating regular inspection and servicing.

Q: Where are Half Flexible Gear Couplings typically used?

A: These couplings are utilized in heavy-duty industrial settings such as power transmission setups, mechanical drives, high-torque motor connections, and pump systems where both reliability and shock-load absorption are critical.

Q: What are the key benefits of using these couplings in high-torque applications?

A: Key benefits include superior misalignment tolerance, long service life due to robust heat-treated materials, easy maintenance access, and a precision-machined fit that minimizes vibration and ensures consistent power delivery.

Q: How does the black oxide surface treatment benefit the couplings performance?

A: The black oxide coating provides corrosion resistance, enhancing durability in harsh industrial environments and helping maintain the couplings precision fit over time.
