Understanding Coupling Misalignment: Angular, Parallel, and Axial Explained Shaft misalignment comes in three forms: angular (shafts meet at a slight angle), parallel (shafts run side by side but offset), and axial (shafts move slightly toward or away from each other along their length, sometimes called end-float). Every flexible coupling is rated for a maximum amount […]
Jaw Coupling vs Disc Coupling: Which Do You Need? A jaw coupling uses a replaceable elastomeric spider to absorb shock and handle minor misalignment, while a disc coupling uses a stack of thin metal discs to transmit torque with near-zero backlash and no wearing parts. Choose a jaw coupling for general-duty machinery where cost and […]
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 […]
