What Coupling Is Used on a Water Pump in Australia?

Water pump coupling selection in Australia follows a consistent pattern across applications from domestic tank pressure sets to large water treatment plant centrifugal pumps serving hundreds of thousands of people. The fundamental requirement is the same in each case:...

Which Coupling Is Best for Gearbox Connections?

Gearbox connections present coupling selection challenges from both sides: the input coupling must accommodate the motor speed and protect the gearbox input bearings from motor vibration; the output coupling must handle the much higher output torque and protect the...

Why Use an Elastomeric Coupling for Vibration Damping?

Every motor-driven machine produces torsional vibration. The motor produces cyclic torque ripple at the electrical supply frequency and its harmonics. The pump or compressor produces pressure pulsations that appear as torsional excitation. The VSD, if fitted, produces...

How to Size a Shaft Coupling in 5 Steps

Sizing a shaft coupling correctly takes less than 15 minutes when you know what to calculate and in what order. The process that causes confusion in most maintenance organisations is skipping steps — typically selecting a coupling by bore diameter alone, then...

Which Coupling Is Best for Food Processing Equipment?

Food processing machinery imposes coupling requirements that rarely appear in standard industrial coupling catalogues. The combination of hygiene compliance, washdown resistance, food-grade elastomer specifications, and the need for smooth surfaces that do not trap...

How to Choose a Coupling for a Servo Motor Application

Servo motor coupling selection is governed by requirements that rarely appear in general industrial coupling specifications: zero backlash, high torsional stiffness, low inertia, and compatibility with the servo control loop dynamics. A coupling that is perfectly...
