Oldham Couplings

NBK's Oldham couplings consist of two hubs and a spacer, characterized by high tolerance for misalignment.
By allowing sliding between the hub and spacer, they accommodate significant eccentricity and angular misalignment.
They are easy to assemble from a disassembled state and can be smoothly installed in equipment. Even with shaft misalignment, eccentric reactive force is suppressed, ensuring stable power transmission.

View problem solution examples
Couplings that support minimal outgassing and large eccentricity are required 【High sanitation / corrosion-resistant / clean】
Coupling maintenance frequency must be drastically reduced 【Workability / maintenance】
