Versatile Power Transmission Solutions

Engineered to deliver reliable and flexible power transmission, tyre couplings seamlessly accommodate a wide torque capacity range and provide exceptional misalignment capability. Their shock-absorbing design makes them ideal for machinery such as pumps, compressors, and conveyors in challenging environments like mining, steel, and cement plants.

Maintenance-Free and Durable Construction

These couplings are virtually maintenance-free owing to their robust cast iron flanges and high-quality natural or synthetic rubber elements. Installation is user-friendly, requiring no lubrication. Maintenance is limited to inspection and tyre replacement only when wear or damage is observed, ensuring long-term, trouble-free operation.

Superior Material and Performance Standards

Built to last, tyre couplings feature painted or coated flanges for excellent corrosion resistance and a rubber element engineered for outstanding oil, grease, and abrasion resistance. They comply with stringent standards, offering assurance of quality, safety, and operational reliability for critical machinery.

FAQs of Tyre Couplings:

Q: How are tyre couplings installed, and do they require lubrication?

A: Tyre couplings are designed for easy, straightforward installation. They do not require lubrication, simplifying maintenance and reducing downtime. The coupling consists of two metal flanges and a rubber tyre element secured with fasteners.

Q: What maintenance is needed for tyre couplings?

A: These couplings are virtually maintenance-free. Routine inspections are recommended, but the only required action is replacing the rubber tyre element if it shows signs of wear or damage. All other components are designed to be long-lasting and resistant to harsh operating conditions.

Q: Where are tyre couplings commonly used?

A: Tyre couplings are widely used in industrial settings such as mining, cement, power generation, steel processing, agriculture, and beverage production. They are ideal for pumps, compressors, conveyors, and other rotating machinery that benefit from their vibration damping and misalignment compensation capabilities.

Q: What makes tyre couplings beneficial for power transmission?

A: Their flexible design allows tyre couplings to accommodate substantial misalignment (axial 2 mm, angular 4, radial 4 mm) while efficiently absorbing shocks and vibrations. This prolongs equipment lifespan, enhances operational safety, and ensures smooth power transmission even in demanding conditions.

Q: When should the tyre element in the coupling be replaced?

A: The rubber tyre element should be replaced if it becomes worn, cracked, or damaged during operation. Regular visual inspections help identify any signs of deterioration and ensure reliable coupling performance.

Q: How do tyre couplings handle harsh environments?

A: With robust cast iron flanges and high-quality natural or synthetic rubber tyres, these couplings offer strong resistance to oil, grease, abrasion, and corrosion. Painted or coated surfaces further enhance durability, making them suitable for tough industrial environments.

Q: What industry standards do these tyre couplings meet?

A: These couplings comply with IS 1878/Part 1-1988 or equivalent international standards. This assures users of consistent quality, safety, and compatibility in industrial applications.
