Dodge Para-Flex elements are manufactured with reinforcing fabric tension cords that transmit much of the torque during operation and offer a wear indicator to the user when the element should be changed out. The uniform and centered beads, in the foot of the tire element prevent it from pulling out during operation. Additionally, the tire […]
Shaft collar evolution
The first mass-produced collars were used primarily online shafting in early manufacturing mills. These early shaft collars were solid ring types, employing square-head set screws that protruded from the collar. Protruding screws proved to be a problem because they could catch on a workmen’s clothing while rotating on a shaft, and pull them into the […]
KTR developing a new servo coupling
KTR has developed a steel lamina coupling for servo drives in the higher power range. The backlash-free and torsionally rigid RADEX-NC High Torque covers speeds up to 27,500 rpm while transmitting torques up to 2,000 Nm. Main application ranges are machine tools as well as measuring and test bench technology. KTR will introduce the coupling […]
Split hub clamps
Custom designed split hub clamps that can be manufactured to OEM specifications for use with hollow shaft motors, encoders, and gearboxes are being introduced by Stafford Manufacturing Corp. of Wilmington, Massachusetts. Stafford Split Hub Clamps are available in one and two-piece clamp-style designs machined from a variety of materials with special features such as wider […]
Locking devices: basic designs and applications
A locking device is a mechanical component that prevents mated shafts and other machine elements from moving out of position when subjected to external forces. Operating conditions such as initial installation error, temperature variations, vibration and others can all cause issues. These are critical components. The safety of an entire system often relies on locking devices. […]
Update on flexible-coupling considerations for OEM and plant designs
All couplings transmit torque and angular velocity. Flexible variations compensate for misalignment. Many of the latter even address vibration and improve system dynamics. Design considerations include machine or installation construction and backlash, torsional stiffness, damping, inertia, torque ratings, maximum rpm, size, misalignments, ease of installation, robustness, and cost. For power transmission (as in motors for […]
PTDA’s industry research reports accelerating growth in 1Q2017
The first quarter 2017 Sales History & Outlook Report (SHOR) released by the Power Transmission Distributors Association showed power transmission/motion control (PT/MC) distributor sales began to rise. The most recent 12 months of sales remain 1.9% below the year-ago level, but several positive indicators suggest total sales will be above the year-ago level in the […]
R+W bellows couplings for spindle applications
R+W Coupling Technology (based out of Klingenberg, Germany) has announced two new products to its bellows coupling line: the SP6 elastomer and SP3 bellows coupling for spindle applications. These couplings feature an external clamping ring system, with the base hub components held to a very high level of concentricity between the two respective bores during the […]

Over 2050 exhibitors from 45 countries will be showcasing their newest products and services at the world’s largest metalworking tradeshow. This year’s EMO motto – “Connecting systems for intelligent production” – conveys current topics and trends in the industry. Companies […]
End-to-end coupling solutions for cranes and hoists
When it comes to gearbox coupling applications, some misalignment is unavoidable. This is especially true for cranes and hoists due to their very heavy loads. Fortunately, you can manage misalignment by choosing the right couplings. Here are some options specifically for cranes and hoists: Connecting the Gearbox and Cable Drum Recommended for crane-lifting mechanisms, barrel […]
