Coil springs and wave springs are both types of compression springs, meaning the spring’s force increases as its axial length decreases (as the spring is compressed). But coil springs and wave springs react differently to applied loads, especially in terms of how stresses are created in the material, which in turn, affects their working load […]

Three torque-limiter options compared (and trip torque explained)
Industrial robots, conveyors, wind turbines, machine tools, packaging machines and pumps are just some of the places you’ll find torque limiters. By Lawrence Kren • Contributing writer Torque limiters actuate on the order of milliseconds to prevent overload, shock, and torque spikes that could otherwise damage components or shorten operating life. They also serve in […]
Electromagnetic-actuated clutches engage polyethelene sheet rolls quickly and accurately
Engaging individual polyethylene sheet rolls with no system downtime is accomplished with speed and accuracy using Miki Pulley CSZ Clutches. Continuously operating via servo motor power by way of a V-belt, individual roll spools automatically switch on/off as programmed when engaged by the CSZ clutches. These high-performance clutches function using electro-magnetic force generated by an […]

What are electromagnetic power-off brakes and where are they used?
Power-off brakes are commonly used in motion control applications for stopping or holding a load (or both), especially on vertical axes or for emergency stop functionality in servo applications. Power-off brakes are so named because the brake is engaged when power is removed from the system — either intentionally or accidentally. (Power-off brakes are also […]
New cam followers address axial loading, provide maintenance-free operation
IKO International has introduced the CR…BSE Series of imperial cam followers, offering machine designers a versatile, reliable way to convert rotary motion to linear motion. Designed to resolve the main factors that can cause bearing failure, these heavy-duty cam followers feature two IKO innovations: A ThrustDisk seal – This special seal slides into the outer […]
What’s the current status of AGMA and ISO gear quality standards (and why are they so confusing)?
Gear quality standards developed and published by the American Gear Manufacturers Association (AGMA), have dominated gear manufacturing in the U.S. market since the 1960s. But in the 1990s, AGMA began working with the International Organization for Standardization (ISO) to update and harmonize gear quality standards, with several versions of both AGMA and ISO standards published […]
