A line of heavy-duty steel shaft collars and flange mounts that can be modified for demanding industrial, processing, and recycling applications has been introduced by Stafford Manufacturing Corp. of Wilmington, MA. Stafford Heavy-Duty Mounting Components feature designs with wider bodies and heavier clamping screws than conventional parts and are manufactured to specification with modifications such […]
Custom Ameriflex couplings for polymer resin pumps
A major global petrochemical company experienced a coupling failure on a polymer pump in one of its larger resin processing facilities. The coupling problem caused expensive, time-consuming production line shutdowns. Ameridrives was contacted to provide a solution. Gear couplings were initially installed on all the polymer pumps between the pumps and gearboxes for this high-torque, […]
Common coupling installation mistakes
Initial coupling selection aside, the prevention of premature component failure begins with installation. Installing the right part the wrong way is bad— seems obvious. Yet, nearly all coupling manufacturers we speak with have similar tales of installation nightmares. Mike Parzych, Product Marketing Manager at GAM gave us the 3 most common installation mistakes he encounters. […]
How do you select couplings when expecting large loads?
Edited by Mike Santora When expecting large loads for a motion system design, a few things need to be considered in addition to the usual. First, the stakes are a bit higher; the amount of physical damage potential increases, and the cost of said damage compounds. With safety being the paramount concern for any engineer, […]
How is shaft vibration and couplings misalignment related?
Edited by Mike Santora If you design a machine and fail to notice there is significant shaft vibration you end up feeling it—both literally and financially. Misaglignment leads to shaft vibration, which can subject the driven shaft of your motion system to load increases, which leads to components bending, which leads to…well, you get the […]
Coupling widens torsional stiffness range
Engine flywheel couplings have to strike a delicate balance when it comes to stiffness. On the one hand, they have to be rigid enough to transmit torque efficiently and avoid resonance problems. On the other, they have to be flexible enough to handle any misalignment between the motor and the drive shaft. The Ringfeder Power […]
How the right coupling can increase safety and reliability in mines and quarries
Choosing the right coupling for your mine or quarry is probably more critical than you think. Typically applied on key capital plant, such as grinding mills, crushers, conveyors and walking draglines, reliability of your coupling is essential for maintaining high levels of production. Couplings can also be found fitted to the pit-head winder, hoisting both […]

Using torsional stiffness to measure torsional rigidity in couplings
By Joyce Laird, Contributing Editor What is torsional rigidity and why measure it? Mike Parzych, Product Marketing Manager at GAM explains that Torsional rigidity is the ability of an object to resist torsion or in layman’s terms “twisting”, due to an applied torque. “While many factors may be involved, coupling torsional rigidity is very important […]
