Frequently Asked Questions
What type of coupling should I use?
Jaw couplings with elastomeric spiders are the most common — simple, economical, vibration-damping, and electrically isolating. Gear couplings handle high torque and misalignment for heavy industrial use. Disc couplings offer zero-backlash and high torsional stiffness for servo/precision applications. Grid couplings provide excellent shock absorption for high-inertia loads.
