Custom made

NBK customized coupling is one of a kind!

  • Infinite Specifications
  • NBK designs and produces a customized coupling with specialized slits even if it is only a single piece!

When making inquiries regarding custom couplings, please provide the following information

  1. Outside Diameter: A, Overall Length: W, Length of Hub: L
  2. Bore Diameters: D1×D2 (Please specify both bore diameters)
  3. Specifications: Max.Torgue, Statie Torsional Stiffness, Max. Rotational Freguency, Errors of Eccentricity, etc.
  4. Attachment: Setscrew type, Clamp type, Keyway type, etc.
  5. Material: Aluminum Alloy, Stainless Steel, Beryllium Copper Alloy, Titanium, etc.
  6. Surface Treatment: Anodizd Coating, Plating, Chemical-polish, Clean Wash etc.

NBK slit couplings securely and accurately transmit power and rotations from servomotors/stepping motors to devices like ball screw, etc.
Since these custom couplings are constructed of a single material, they are ideal for use in environments that limit the use of certain materials such as clean room environments.

Evaluate the coupling stress and misalignment experienced under various conditions of use

The latest FEM analysis techniques are employed to evaluate the coupling stress and misalignment experienced under various conditions of use.

Evaluate the coupling stress and misalignment experienced under various conditions of use

We can customize slit design, pitch, depth and slit quantity to create a coupling that fits your exact needs.

Select the best slit pattern according to your specifications.

The optimal coupling specifications can be reached through adjustment of pitch, depth, and slit quantity.
