Flexible Couplings

MECHANICAL CONNECTIONS BUILT FOR TORQUE, ALIGNMENT, AND RESILIENCE

Flexible couplings are essential mechanical components that connect two rotating shafts, transmitting torque while compensating for misalignment, vibration, and minor axial movement. They play a critical role in maintaining the efficiency and longevity of motor-driven systems — particularly when precise alignment is difficult or dynamic loads are present.

At Valiadis S.A., we offer a full range of KOPLER and MAX-REX flexible couplings designed for industrial electric motor applications. Manufactured to exacting standards and available in a wide range of sizes, our couplings ensure secure power transmission across varying operating conditions.

Product Highlights

• Rated speeds up to 8200 rpm
• Effective for compressors, pumps, and general drives

MAX-REX Series
• Heavy-duty torque transmission
• For shaft diameters from 10 mm to 110 mm
• High power capacity up to 656 HP (482 kW)
• Designed for smoother rotation and shock absorption
• Ideal for larger drive systems and low-speed high-torque applications

Key Advantages

• Absorb misalignment and vibration

• Extend the lifespan of bearings and motor shafts

• Easy to install and maintain

• Available in multiple bore sizes and lengths
