Addax Composite Cooling Tower Couplings
Rexnord Addax
Cooling Tower Coupling
Lightweight, floating shaft spacer coupling specifically designed for the harsh rigors of cooling tower applications.
Rexnord® offers Addax® products to satisfy all your cooling tower coupling needs. Floating shaft couplings are used to connect units which are relatively far apart. Such arrangements are particularly suited to transmit power into areas where moisture, dust or corrosive conditions would adversely affect the driving machinery. Typical applications include cooling tower fan drives, paper machinery, printing press, pumps and compressors.
The Addax® coupling are designed and manufactured specifically for cooling tower applications. Performance ratings and materials of construction are in accordance with the Cooling Tower Institute (CTI) standards and specifications.
Composite floating shafts can also be utilized to provide lighter weight, longer spans or higher speeds than can be achieved with steel tubes. Rexnord® can design and manufacture light weight, advanced composite couplings to suit your needs.

Why choose Rexnord Addax Couplings?
Lightweight, floating shaft spacer coupling specifically designed for the harsh rigors of cooling tower applications.
Proven & Trusted Performance
With over 70,000 couplings installed across the world, Rexnord Addax is the most specified coupling globally in the cooling tower industry. Customers continually select Addax Composite Couplings when dependable performance is a must.
Rapid Installation & Maintenance
The advanced composite, full-floating center section weighs less than 25% of a
comparable steel spacer. Most Addax coupling assemblies weigh less than 100
pounds, often times eliminating the need for cranes and special lifting equipment
and assisting maintenance personnel in handling and installation.
Extends System Life
Lightweight advanced composite materials used in Addax® couplings increase
the critical speed, reduce vibration and extend bearing life. When compared to
alternative metal couplings, the Addax coupling reduces overhung bearing loads
up to 80%.
Eliminates Intermediate Bearings
The rigid center member and light weight design of the Addax coupling span the
distance from motor to gearbox, without intermediate support bearings.
