Coupling replaced without the need to dismantle the drive

Coupling replaced without the need to dismantle the drive

What do you do when one of the most versatile and reliable flexible couplings reaches the end of its working life and you need to fit a replacement, quickly? As part of the CENTAFLEX-A range, the CENTAFLEX-AR from Centa is designed for use on 'O’ type couplings size 25 to 600, enabling engineers to replace that worn out CF-A coupling quickly and easily. Most importantly, you can do it without the need to strip the drive.

Whilst the CENTAFLEX-AR is a single-piece coupling with exactly the same vibration and noise eliminating attributes as the conventional CF-A, there is one critical difference. The CF-AR is split at one point; this means that it can be installed around the drive, without the need to dismantle it. All that needs to be done is to cut the old coupling away and then slot the replacement CF-AR around the shaft. You then simply bolt the ends of the new coupling together, using the two washers provided and the installation is complete within minutes.

This means that operational downtime is minimised and precious time and money can be saved, without any loss of operational performance. Centa says CENTAFLEX-A is one of the most versatile flexible couplings available and is installed in countless applications in many different industries. Not only does it overcome four-way misalignment, it is available in a wide range of model types and SAE sizes, and copes with a wide range of nominal torques.

It is used in a plethora of applications in the plant, rail, marine and wind power industries, connecting the gearbox, electric motor, compressor, PTO drive, generator, pump, driveshaft or water jet to the diesel engine or hydraulic drive.

Centadisc-C connection option makes installation easier

Another recently introduced product from Centa, the Centadisc-C coupling, which can be used with steel, composite, and super-lightweight carbon fibre shafts, now has a new connection option that means the flexible coupling and shaft can be installed in two parts, rather than as a single unit. This means that the problems caused by small bulkhead apertures and a lack of space are now a thing of the past.

On this new version of the coupling, the centre shaft section and the flanges are connected using a Hirth face spline. This means that the main tube can be fed through any structures in the drive line, before having the larger diameter flanges attached. Smaller openings in structures, such as bulkheads, are no longer a problem.
