Log splitters put jaw couplings through one of the hardest use cases in light industrial equipment. Every cycle — from idle to full hydraulic pressure — generates a sharp shock load through the drivetrain. Get the coupling wrong and you’ll be replacing spiders every season. Get it right and the coupling outlasts everything else on […]

The Lovejoy L-series is the most widely used jaw coupling range in North America. If you’re replacing a worn coupling or specifying a new drive, this guide gives you every size, bore range, OD, and spider type in one place — plus the equivalent part numbers from competing brands.

The short answer: Use a jaw coupling for general machinery where shock absorption matters. Use a disc coupling where you need zero backlash, high torque, and precise alignment — typically servo systems and high-speed equipment. What Is a Jaw Coupling? A jaw coupling (also called a spider coupling or claw coupling) is a three-piece flexible coupling: […]
