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 […]
