 | Optimize mechanical misalignments, get hidden benefits
C-Flex Couplings combine the best qualities of disc, beam, and bellows couplings in a unique and economical new design. Made to couple two rotating shafts together, these couplings can accommodate large misalignments while transmitting high torque loads with zero backlash. Benefits include lower energy usage and less frequent bearing failure, since less stress is placed upon bearings. Constructed using high-strength hardened stainless steel or glass impregnated polyamide flexures, these couplings require no maintenance and provide years of trouble-free life, even in contaminated environments. Flexible Pivot Bearings and Super Plastic Torsional Damping Couplings also available.

How to install a coiled spring pin
Coiled pins were designed with assembly in mind. Compared to other pins, their square ends, concentric chamfers, and lower insertion forces make them ideal for easy installation. They can also accommodate wider hole tolerances than any other pin. Learn why coiled pins are the easiest type of pin to install and are designed to be serviceable. By Jeff Greenwood, SPIROL

 | Ford Bronco R race prototype is sneak peek at new production model
The Bronco is set to be reborn in 2020, and Ford gave us a sneak peek (although a cryptic one) of what it may look like recently when it entered the Bronco R race prototype in the punishing Baja 1000 off-road race. Specially developed by Ford Performance, the heritage-inspired design gave a hint of the new vehicle's boxy proportions and was built using the upcoming production model's body-on-frame architecture.

 | How to prevent step losses with stepper motors
When a stepping motor does not operate correctly in a specific situation, the common conclusion is that either the motor or the drive electronics are faulty. However, other factors can contribute to step losses. Mini-motors expert MICROMO runs through important things to examine for the analysis of step losses or non-operation across a variety of applications.

 | New compact, tough angle sensors
Novotechnik has just introduced the Vert-X 1600 Series of angular position sensors, which are ideal for industrial, medical, off-highway vehicle, and other applications. They convert rotational angle into an analog or digital output, with a measurement range of 0 to 360°, 14-bit resolution, and repeatability of 0.1°. Available analog outputs are 10 to 90 percent of supply voltage and 5 to 95 percent of supply voltage. Digital interface options include SPI and PWM. The sensors are sealed to IP 65, life is ≥ 50 million movements, and MTTF is 668 years. Operating temp range is -40 to 125°C. Will operate with up to 10 N axial or radial shaft load.

 | Next-gen low-friction bearing for improved lubrication
Freudenberg Sealing Technologies has developed an optimized design for its proven Levitorq axial thrust washers. Through a new "scoop" feature, the enhanced Levitorq design is able to collect and push lubrication under the washer to enable higher critical speeds and enhanced performance. A team of experts developed the scoop design based on the types and availability of lubricants used in powertrain applications. These designs help optimize the availability of lubrication at the inner diameter, thus improving lubrication across the washer. These designs are ideal for applications with limited or splash lubrication. Levitorq is part of the company's Low Emission Sealing Solutions (LESS) product portfolio.

 | New integrated DC motor and controller package
Haydon Kerk Pittman has just announced the latest addition to its popular line of brushless DC motors. The EC042B IDEA Motor Series is now available with CANopen communication-enhancing motion control capabilities. Save money and space by utilizing the IDEA Motor's integrated package of motor, drive, and feedback connections in a compact and programmable unit. A single motor/drive unit reduces motion system components by up to 75 percent per axis and simplifies machine troubleshooting. Save time using a pre-engineered, factory-configured and tested servo system. Immediately generate complex precise motion sequences by using the available Graphical User Interface that provides an intuitive programming environment to quickly develop, save, and debug complex motion sequences.

 | Adhesives: The importance of hardness testing
According to Master Bond, measuring hardness is a simple, yet powerful test to ensure proper curing and evaluate the performance of adhesive materials. Why? Hardness is generally a good indication of the product's overall functionality. If the mix ratio used was incorrect or if parts A and B were not mixed thoroughly or properly, the adhesive will cure "tacky" or with blotches. Hardness can also be used to determine how a material is holding up to various experiments and accelerated aging tests.
