Sourcing drum gear couplings abroad need not lock to a GICL model. Three matching values make them interchangeable:
- Same pitch-circle diameter (PCD)
- Same rated torque (and peak / safety factor)
- Same bore / shaft end (keyway / locking type)
Same PCD / torque / bore → the couplings are mutually interchangeable spares, cutting single-supplier dependence and lead time.
Marusaku: build to print; we size from your PCD / torque / bore with a contact-strength check and offer an interchangeable solution.
