Users already know the important role Ringfeder couplings play in heavy-duty equipment, from cranes and hoists to pumps and compressors. But coupling can also make or break applications requiring advanced, precision motion control — like surgical robots, medical device manufacturing, medical imaging, lab automation, semiconductor equipment, and industrial robots. A Rundown of Ringfeder Couplings When […]
Twin Spring Coupling’s flexible coupling technology for replacing U-joints and more
Industrial machinery runs 24/7 365, modern life demands a lot from this machinery and when the equipment is not running it costs money through lost orders, worker down time, and customer dissatisfaction. High speed couplings — couplings, beam and elastomeric, can only run at 4° misalignment before they cause equipment failure through increased vibration and […]
Solar panel mounting system application for modified L-jaw couplings
RBI Solar, a designer and manufacturer of solar panel mounting systems for commercial applications, needed a coupling solution for its new single-axis tracker product. The SunflowerTM mounting system rotates rows of photovoltaic (PV) modules on the East/West axis to follow the sun and maximize energy production. In large-scale commercial installations, rows can be 400-ft long, […]
Elastomer insert jaw couplings from DieQua
For applications requiring higher performance than typical insert couplings, DieQua’s new EC series provides zero backlash, several clamping styles and five different insert types providing varying degrees of torsional rigidity. 3 models provide a variety of connection options, all with zero backlash. 5 insert shore values provide different stiffness ratings. All models offer low inertia […]
Curved jaw flange K45 Series from Guardian Couplings
The K45 Series is a shaft-to-shaft coupling, for industrial applications, with bolt on brake disc for brake calipers. The coupling is designed for industrial applications including various types of cranes and hoists, and mining conveyors, reclaimers and draglines. California Proposition 65 Warning: This product contains chemicals known to the State of California to cause cancer […]
Do jaw couplings help with electrical isolation?
Electrical isolation from a coupling is a common need for many motion system designs. We spoke with Bobby Watkins from Ruland Manufacturing to help us identify one of the most common types of couplings for when you need electrical isolation in your next design. “Electrical isolation: We talked about that some of the designs that will […]
“Jaw spider” couplings from Miki Pulley
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 […]
What are couplings for power-transmission drive shafts?
Updated May 2019 || As outlined in our coverage of couplings for motion control — here at this couplingtips.com article — couplings connect rotating shafts powered by a drive of some type — often an electric motor. All couplings serve to transmit drive torque and angular velocity. But applications for motion control (such as axes […]
Zero-backlash jaw couplings: Drawbacks and benefits
Updated October 2019 by Lisa Eitel || Zero-backlash jaw couplings are suitable for an array of applications. Here, Bobby Watkins of Ruland Manufacturing sheds some insight on their benefits and drawbacks. Zero backlash jaw couplings are our fastest growing product over the last 10 years. They’ve got some great characteristics under the right circumstances. There […]
Jaw couplings for precision conveyors
Ruland zero-backlash jaw couplings have a balanced design, accommodate all forms of misalignment and have high dampening capabilities, making them an ideal fit for precision conveyors with frequent starts and stops. These conveyor applications are often found on equipment used in semiconductor, solar, optical inspection, and medical automation. Jaw couplings offer system designers a wide […]
