Selector guidance, replacement tips and application reminders for Lovejoy coupling decisions.
A cost-focused checklist for buying Lovejoy coupling parts without hidden fees or reorder costs, including L100, log splitter, servo motor, and furnace applications.
Continue readingA procurement manager shares how a tiny Lovejoy coupling spider order saved thousands, reshaped his vendor policy, and proved small customers deserve better service.
Continue readingA quality inspector reviews a shattered L-100 Lovejoy S-Flex coupling and finds the real failure was in the servo motor control system — not the part. A lesson in VFD compatibility, small-customer service, and what quality actually means.
Continue readingA quality compliance manager with 4 years of order-review experience explains why most power transmission failures trace back to system design, not the coupling itself. Covers Lovejoy L150 vs. rigid coupling selection, how VFDs control motor speed, inline gear reducer torque math, and disc brake duty cycles.
Continue readingA maintenance planner's real story about misidentifying a Lovejoy Sier-Bath coupling on a VFD gear motor—and what it taught him about Lovejoy couplings, gear motors, disc brake calipers, and order checklists.
Continue readingA 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.
