Taper Bushing Keyway Standards Guide
Keyway tables for the bushing range use several industry reference systems. The same shaft diameter can be described under different regional conventions, so the required system should be named in the RFQ rather than inferred from country alone.
| Reference system | Selection note |
|---|---|
| DIN 6885 | Metric parallel-key/keyway reference used widely in Europe. |
| JIS B 1301 | Japanese key and keyway reference shown in the available keyway tables. |
| USAS / ASME B17.1 | U.S. keys and keyseats reference; the current ANSI listing is ASME B17.1-1967 (S2023). |
| BS 46 | British key and keyseat reference used by legacy equipment tables. |
| UNI / GB references | Additional regional tables may be used on legacy or imported machinery; confirm the exact required keyway. |
