Ikkita bitta zanjirli tishli g'ildiraklar ikkita bitta zanjirli rolikli zanjirlarni ishlatish uchun mo'ljallangan bo'lib, "ikkita bitta" nomi shu yerdan kelib chiqqan. Odatda bu tishli g'ildiraklar A uslubida bo'ladi, ammo konussimon vtulkali va QD uslubidagi tishlar mijozlarning iltimosiga binoan ishlab chiqariladi. Bizning ikkita bitta zanjirli tishli g'ildiraklarimiz qattiqlashtirilgan tishlar bilan ishlab chiqariladi va yuqori ishlash va ozgina korroziyaga chidamlilik uchun asl rang yoki qora oksid qoplamasiga ega. Ikkita bitta zanjirli tishli g'ildiraklarning standart o'lchamlari ANSI #40 dan #80/DIN06B-16B gacha, ammo qo'shimcha o'lchamlar buyurtma asosida ishlab chiqarilishi mumkin. Shuni ta'kidlash kerakki, bu tishli g'ildiraklar ikki zanjirli bo'lsa ham, ular ikki zanjirli rolikli zanjir bo'lmaydi.
