By Mike Santora “If it ain’t broke, don’t fix it”— an old phrase perhaps most appropriate in reference to the coupling selection for a future design. With time constraints moving at the speed of commerce, designers go with what they know has worked in the past. That’s a legitimate argument. Plus, there is no reason […]
What are new alternatives for vibration damping?
By Joyce Laird, Contributing Editor Vibration damping reduces noise in applications ranging from appliances, vehicles and ships to all types of industrial machinery. By dissipating vibrational energy from substrates into other forms of energy it serves to reduce both noise and vibration resonance in the end product. Noise, vibration and harshness (NVH) can adversely affect […]
Coming to America: NBK talks ancient history and new future
By Mike Santora It would have been all but impossible to predict anything like the concept of modern motion control 456 years ago. Forget the modern coupling, not even the pencil (1564) had been invented when Nabeya Bi-tech Kaisha (NBK) was founded in 1560. So, while the motion control component company’s new U.S. subsidiary NBK […]
What is a hysteresis coupling?
By Zak Khan Hysteresis refers to a specific magnetic phenomenon. Certain magnetic materials, called ferromagnetic materials, have a tendency to remain magnetized to some degree even after the magnetic field they are subjected to is removed. This “memory of magnetic history” is referred to as hysteresis. This also means a magnetic field in the opposite […]
New ranges to be launched at Drives & Controls 2016

What is a line shaft?
By Zak Khan Line shafts may conjure up images of Industrial Revolution-era factories, with whirring belts and machines, but just what is a line shaft and are they still relevant today? In the simplest definition, a line shaft is the rotating shaft part of a system of mechanical couplings between the power source in a […]
