1. Product definition and structure
Type: Rigid disc coupling (with limited flexibility compensation capability)

Core structure:

High strength steel disc assembly (usually made of stainless steel or alloy steel)

Pre tightened bolt connection (without elastic components)

Laser cutting/CNC machining forming (ensuring dynamic balance accuracy)

Rigid design features:

Zero backlash in torque transmission

Mainly compensates for small angular/axial deviations (usually ≤ 0.5 °)

Suitable for high-precision alignment of transmission systems

2. Key performance parameters
Typical parameter range (taking RADEX-NC series as an example)
Torque range 10~50000 Nm
Shaft hole diameter 10~250 mm
Maximum speed 8000~20000 rpm
Allowable angular deviation of ± 0.3 °~0.5 °
Allowable axial deviation ± 0.1~0.5 mm
Working temperature -50 ℃~+300 ℃ (special coating optional)
3. Core advantages
High rigidity: torsional stiffness up to 10 ⁴~10 ⁵ Nm/rad, suitable for servo systems

Dynamic balance: G6.3 level balance (optional G2.5 level, used for high-speed scenarios)

Maintenance free: No wear parts, no lubrication required

Compact design: saves 50% space compared to gear couplings

4. Typical industrial applications
Machine tool industry:

CNC lathe spindle motor direct connection

Five axis linkage machining center rotary axis

Energy equipment:
