Ví dụ về ký hiệu quy ước của bánh đai sử dụng đai truyền hình thang mặt cắt A, 3 rãnh, đường kính tính toán d_tt = 224 mm, lỗ ghép hình trụ d = 25 mm.

Bánh đai A2.224.25T                              TCVN 2338:1978

Cũng vậy đối với bánh đai có lỗ ghép côn:

Bánh đai A2.224.25C                             TCVN 2338:1978

3. Kích thước prôphin của rãnh và yêu cầu kỹ thuật theo TCVN 2342:1978.
