In the world of mechanical power transmission, couplings play a crucial role in connecting two shafts together to transmit power while accommodating misalignment, absorbing shocks, and reducing vibrations. Selecting the right coupling can enhance efficiency, reduce downtime, and protect your equipment. Let’s explore the different types of couplings and their respective advantages.

🔧 1. Jaw Couplings
One of the most common types of flexible couplings, Jaw Couplings consist of two metal hubs and an elastomeric "spider" between them.

Benefits:
Compact and simple design

Absorbs shock and vibration

Easy maintenance

Ideal for light to moderate torque requirements

🔧 2. Tyre Couplings
Tyre Couplings use a rubber or synthetic tyre element to flex under misalignment. This type is known for its high flexibility and vibration damping characteristics.

Benefits:
Excellent for applications with frequent misalignment

Reduces transmitted vibration

No lubrication required

Easy replacement of tyre element without disturbing the drive
