Identification of basic design
| RT . . | Worm-gear unit with the solid input shaft |
| MRT . . | Worm-gear unit with an electric motor or with hollow input shaft fitted with a flange for B5 mounted electric motor or B14A mounted motor or B14B mounted motor |
| MRP . . | Worm-gear unit with spur gear step (i = 3) at the input shaft |
| MAT . . | MRT worm-gear unit with ATC in-line gearbox at the input shaft ( i = 3,4 and/or i = 6, and/or i = 8 |
| MRT . . x . . | Combination of two worm-gear units to achieve very high gear ratios i = 4,000. Gearbox combinations up to i = 10,000 ratio are available as an option. |
