KTR BOWEX 65 Curved Tooth Coupling — Angular Misalignment Compensation

KTR BOWEX 65 Curved Tooth Coupling — Premium Misalignment Tolerance for Saudi HVAC and Pump Applications

The KTR BOWEX 65 is a curved tooth (CUSP) flexible coupling designed for applications requiring superior angular and radial misalignment compensation. The BOWEX curved tooth design distributes load across multiple engagement points, dramatically extending service life in cooling water pumps and HVAC systems in Saudi commercial and industrial buildings.

Saudi Arabia HVAC sector — district cooling plants, hospital complexes, and data centers in Riyadh and Jeddah — demands couplings that handle shaft misalignment from thermal expansion. The BOWEX 65 handles up to 1 degree angular misalignment and 0.6mm radial offset without accelerated wear.
