Best Couplings for Servo Motors Beam (helical) and disc couplings are the two best choices for most servo motor applications, because both deliver the zero-backlash, high torsional stiffness performance precision motion control demands. Beam couplings suit lighter loads and tighter budgets — encoders, small CNC axes, 3D printer motion systems. Disc couplings step up for […]

Understanding Coupling Misalignment: Angular, Parallel, and Axial Shaft misalignment comes in three forms — angular (shafts meet at an angle), parallel/offset (shafts run parallel but off-center), and axial (shafts move toward or away from each other along their centerline). Almost every real-world installation has some combination of all three, which is exactly why flexible couplings […]
How to Measure Coupling Bore Size (Without Guessing Wrong) Bore size is the diameter of the hole in a coupling hub that the shaft slides into — and it’s the single most common reason a coupling order gets returned. Measure your shaft with a digital caliper at the point where the coupling will sit, not […]

Best Couplings for Log Splitters Engine-to-Pump Coupling Guide Most gas-engine log splitters connect the engine to the hydraulic pump with a jaw-type coupling, and it’s usually the first thing to fail after the pump seals. Here’s what to look for in a replacement and which sizes fit the most common splitter builds. Why Log Splitters […]

Jaw couplings and disc couplings both connect two rotating shafts while absorbing misalignment, but they solve the problem differently. Jaw couplings use a flexible spider insert for shock absorption and easy field replacement; disc couplings use thin metal discs for a zero-backlash, high-precision connection. Here’s how to pick the right one. Jaw Couplings: Built for […]
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. Lovejoy L-Series Size Chart Size Bore […]
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: […]

Best U-Joints for Classic Muscle Cars: Spicer or Moog? Classic muscle cars have a unique place in automotive history, loved by enthusiasts for their powerful engines, sleek designs, and iconic style. But maintaining these vehicles requires careful attention, especially when it comes to critical components like universal joints (U-joints). When a muscle car’s original U-joints […]
