If you want a wear-free way to join shaft components, look no further than locking assemblies. These frictional devices take the place of keyed connections that wear and slip over time. Let’s take a closer look at how locking assemblies work — including their advantages over traditional keyways in high-torque applications. What is a frictional […]

Edited by Mike Santora The Challenge After maintenance engineers had examined the ball mill unit thoroughly, the cause of the problem seemed to be the shaft-pinion connection, or to be more exact, the locking assembly that connected the solid shaft with the pinion. Measurements showed the assembly to be out of tolerance by a whopping […]

Miki Pulley is introducing its SFM coupling line for direct sale to OEM’s in North America.

EPR Series right-angle bevel planetary gearboxes from GAM Enterprises deliver the quality and cost advantages of the manufacturer’s EPL inline gearboxes but in a right-angle configuration. The gearboxes come with precision-ground spiral bevel gears on the input stage and GAM Enterprises EPL or PE inline gearbox elements on the planetary stage. EPR Series planetary gearboxes are […]

Miki Pulley’s ALS couplings are general purpose power transmission couplings designed to transmit torque by connecting two shafts while damping system vibrations and accommodating misalignment. With a “Curved Jaw” design, ALS couplings feature a polyurethane elastomer element (called the spider) between two sintered aluminum hubs. The three-component assembly fits together with a jaw from each […]

Posi-Lock bushings provide a solid connection between shaft and mounted devices. They provide system designers with a keyless option for locking into position gears, pulleys, sprockets and other components in a mechanical system. Posi-Lock bushings feature socket-head cap screws that tighten quickly and easily. When tightened, these screws allow the inner and outer hub of…

Despite the buzz about the IoT and the IIoT, the development of tools and programs for the design of IoT systems and equipment are still embryonic. But there are signs of progress. Here’s what industry leaders are saying about developments in IoT technology. Leslie Langnau, Managing Editor The Internet of Things (including the Industrial Internet…

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. […]
