Component Specifications

Definition
A coupling probe or pin is a critical component in input/output couplers designed to ensure precise alignment and secure connection between rotating or stationary machine elements. It functions as a male connector that engages with corresponding female receptacles to transmit torque, motion, or signals while maintaining positional accuracy and minimizing misalignment forces.
Working Principle
The coupling probe/pin operates on the principle of mechanical interference fit or keyed engagement. When inserted into a mating receptacle, it creates a rigid connection that transfers rotational forces while maintaining axial and radial alignment. Precision-ground surfaces ensure minimal clearance for vibration reduction and optimal power transmission efficiency.
Materials
Typically manufactured from case-hardened alloy steel (e.g., AISI 4140, 4340) or stainless steel (e.g., 17-4PH, 316SS) with surface treatments including nitriding, chrome plating, or black oxide coating for corrosion resistance and wear protection.
Technical Parameters
  • Length Range 10-200 mm
  • Straightness 0.01 mm/100 mm
  • Load Capacity Up to 500 N·m
  • Surface Hardness 58-62 HRC
  • Diameter Tolerance ±0.005 mm
Standards
ISO 9409, DIN 332
