DNCG Stainless Steel Rigid Coupling – High Rigidity, High Torque for Servo & Stepper Motors

Model Number
Check below, custom

Product Description

The DNCG Stainless Steel Rigid Coupling is designed for applications requiring zero backlash, high torsional stiffness, and maximum torque transmission. Manufactured from a single piece of SUS304 stainless steel, this coupling ensures exceptional strength and corrosion resistance, making it ideal for servo and stepper motor systems where precise shaft alignment is maintained.

One-Piece SUS304 Stainless Steel – Superior strength, corrosion resistance, and durability
High Torque Capacity – Handles demanding loads without slippage or deformation
Zero Backlash – Rigid design eliminates any rotational play, ensuring precise motion control
Clamp-Style Locking – Provides secure, even shaft clamping without damaging the shaft
High Torsional Stiffness – Maintains angular accuracy under dynamic loads
