ZBG Gear Coupling

• Torsionally rigid curved-tooth coupling
• ‍Nominal torque range up to TKN = 3,000 Nm‍
• ‍Temperature range: from –50 °C to +55 °C‍

‍

‍Good connections thanks to quality‍

The torsionally rigid coupling has a robust, weight-optimized design. Heavy parts are directly attached to the motor or gear unit shafts; the coupling’s inner components compensate for any operational misalignments so that only the slightest unbalanced forces and oscillations apply. The patented slip hub protects the drive system. Sealed grease chambers prevent the lubricant from escaping and eliminate the potential fire risk.‍
