Despite current CNC machine tool crash protection strategies which include both proactive avoidance through CAD/CAM programming and reactive damage reduction methods that include electronic sensors and mechanical overload clutches, machine tool crashes are still commonplace. In these machine tool crashes, tool collisions with high feed rates cause high forces on motor spindles. Depending on the […]

How do you select the right coupling when electrical isolation is a priority?
By Joyce Laird, contributing editor Understanding design challenges Most of the couplings on the market today are either partially, or entirely, made of metal. Since metal is such a good electrical conductor it can be a challenge for the design engineer to find a suitable product to serve as a flexible coupling for transmitting torque […]
Timken Quick-Flex couplings
Timken Quick-Flex elastomeric couplings are durable enough to face the challenges of harsh environments, yet need minimal maintenance. They are easy to install and require no lubrication. Timken Quick-Flex couplings operate without any metal-to-metal contact. Because the metal hubs don’t wear, the elastomeric insert is the only spare part users will need. For especially harsh […]
The year in couplings 2016: GAM
For this multi-part series, Coupling Tips.com reached out to several coupling industry professionals to get their take on the year in couplings. Here, GAM Technical Marketing Manager, Mike Parzych looks back on 2016 and gives a few predictions for the new year. Coupling Tips: What do you think was the biggest event in the industry […]
ROBA-DS shaft couplings tested by DNV GL
The compact ROBA-DS disk pack couplings by mayr power transmission have been certified by DNV GL. They ensure maximum safety for users on the high seas. Whether in the drives of ship propellers, mobile platforms such as drilling platforms for oil and gas extraction, or also in tidal power plants – the areas of application […]
R+W Releases STE safety coupling with elastomer connection
R+W has recently narrowed the gap between its classic precision and industrial drive safety couplings with the new STE series. Featuring the well proven technology of the ball-detent safety element system, which disconnects drivelines within milliseconds of a torque overload event, this version is more cost effective and available in smaller sizes than the standard […]
Overload protection for hard to access drives
EAS-reverse – the disengaging torque limiter with automatic re-engagement With their EAS-reverse, mayr power transmission has developed a new, disengaging torque limiter on which all functional processes can be automated through the drive. It is easy to handle, permits long run-out times and re-engages again through slow backwards rotation. A housing also makes the clutch […]
Couplings tips for specific installation requirements
Coupling variations complement specific machine dynamics and meet specific application criteria. Rigid coupling designs handle drive components already in alignment and flexible couplings compensate for post-installation misalignments. Misalignment potential, temperature, mechanical resonance and other factors make some couplings better suited for given applications. Here are some different coupling types and their most common applications. Rigid […]
Hip to be square: New U-joint “square ball” design is smoother than it sounds
By Mike Santora The “u” in U-joint could just as easily stand for ubiquitous or unchanged. But unique? Hardly. For almost a century, universal joints have been created with the same fundamental design. Sure, they’ve been improved since their first incarnations; they’ve gained needle bearings, increased machining qualities, and lubrication and sealing abilities. Regardless, the […]
