Product description
Compiled from the existing technical description of this product on this site
The Gen-3 elastic locating pin comprehensively reinforces load capacity on the basis of the Gen-2 press-in structure: the sleeve outer diameter is increased to Ø6.50±0.02mm, markedly improving mounting rigidity and side-force resistance; the pin now uses 20MnCr5 carburizing and quenching with surface hardness 58~62HRC and case depth 0.4~0.8mm while the core stays tough — this “hard outside, tough inside” microstructure gives both wear resistance and fracture resistance under heavy load and impact. The 23° lead angle combined with the dual-diameter design (Ø3.80/Ø3.95) balances smooth insertion and locking strength; the SUS304 spring provides a constant 10±3N compression force to keep the pin in continuous contact with the mating face. Suitable for heavy-duty bearing location and assemblies with prominent vibration and shock loads.
