Selector guidance, replacement tips and application reminders for Lovejoy coupling decisions.
A maintenance engineer answers common Lovejoy coupling questions — grid vs. jaw couplings, torsional ratings, VFD motor compatibility, V-belt sourcing mistakes, and whether rush delivery on shaft couplings is really worth the cost.
Continue readingA rush order story about a failed Lovejoy coupling on a VFD-driven motor. Learn what a Lovejoy flexible coupling actually reduces, when it's not the right fit, and how we saved a shutdown with 16 hours to spare.
Continue readingA quality inspector explains why Lovejoy coupling failures usually come down to measurement, how to verify L099 and L110 hubs, and what Century AC motors, stepper motors, and electric actuator types mean for coupling selection.
Continue readingA procurement manager argues that buying Lovejoy couplings on unit price alone is a mistake. Using an L190 case study, log splitter applications, and VFD/motor matching examples, he makes the case for total system cost—and why efficiency beats cheap parts.
Continue readingComparing Lovejoy S-Flex size 8 and 1 inch Jaw coupling for gear motor and planetary gear reducer repairs. Misalignment, shock, and availability from an emergency parts perspective.
Continue readingWhen a servo motor encoder starts throwing errors or a linear actuator locks up, don't assume the worst. A Lovejoy coupling size chart can pinpoint the real problem fast. Here's how a rush-order specialist uses it.
Continue readingA Lovejoy coupling reduces vibration, shock loads, and minor misalignment. A procurement manager explains when the L070 Lovejoy coupling works with brushless DC servo motors, and when it doesn't.
Continue readingA procurement manager's story about an urgent Lovejoy coupling L-100 order, a size chart check, and why total cost beats sticker price.
Continue readingA procurement manager explains why genuine Lovejoy couplings—including the Lovejoy coupling L100 and Lovejoy grid coupling—often beat cheap alternatives. Also covers disc brake diagram torque, A4988 stepper motor driver builds, and what's a VFD for retrofit planning.
Continue readingFive years of buying Lovejoy couplings for an automation company taught me what matters: spec accuracy, spider durometer, and authorized distributors. Covers L100 jaw couplings, Sier-Bath gear couplings, and when cheaper makes sense.
