Dvigubo žingsnio konvejerio grandinės žvaigdutės dažnai idealiai tinka norint sutaupyti vietos ir yra patvarios ilgiau nei standartinės žvaigdutės. Dvigubo žingsnio žvaigdutės, tinkamos ilgo žingsnio grandinėms, turi daugiau dantų nei standartinės to paties žingsnio skersmens žvaigdutės ir tolygiai paskirsto susidėvėjimą per dantis. Jei jūsų konvejerio grandinė suderinama, tikrai verta apsvarstyti dvigubo žingsnio žvaigdutes.
Dvigubo žingsnio ritininių grandinių žvaigdutės būna vienadantės arba dvidantės. Vienadantės dvidantės ritininių grandinių žvaigdutės elgiasi taip pat, kaip ir standartinės ritininių grandinių žvaigdutės pagal DIN 8187 (ISO 606). Dėl didesnio dvigubo žingsnio ritininių grandinių žingsnio galima padidinti jų ilgaamžiškumą modifikuojant dantis.
