The Multiquip CD290028 Woodruff Key 5X5X12 MM is a genuine OEM component designed for DM15A9C and CDM2CSA series equipment. As a direct OEM replacement, CD290028 meets the original engineering specifications set by Multiquip, ensuring the key seats and locks correctly within the shaft and hub assembly. This part is sourced directly through authorized Multiquip supply channels, making it the straightforward choice when an exact-fit key is required for your drill rig or core drill.
Key Features
- Genuine OEM Specification: — Manufactured to the precise dimensional tolerances required for proper shaft-to-hub engagement, so the key transmits torque without play or stress concentration.
- 5X5X12 MM Profile: — The standardized 5 mm × 5 mm × 12 mm Woodruff key profile seats flush in the keyway, allowing direct installation without filing or shimming.
- Verified Fitment: — Confirmed for DM15A9C drill rig stand and CDM2CSA core drill models — cross-reference your model code before ordering to confirm applicability.
- Torque Transfer Integrity: — A correctly sized Woodruff key holds the driven component in angular alignment with the shaft, preventing slippage that can damage keyways, hubs, and adjacent drive components.
- Direct OEM Replacement: — Part number this part matches the original Multiquip bill of materials, eliminating guesswork when sourcing through DHS Equipment.
A Woodruff key is a small, semi-circular or rectangular metal key that fits into a machined slot — called a keyway — on both a shaft and the hub of a mounted component such as a pulley, sprocket, or drive gear. Its purpose is to lock the two parts together rotationally so that torque is transferred from the shaft to the driven component without slippage. When a Woodruff key shears, wears, or goes missing, the mounted component will spin freely on the shaft rather than turning with it, resulting in immediate loss of drive function and potential damage to the keyway itself. Replacing a worn or failed key promptly with the correct OEM-specification part restores full torque transfer and protects the surrounding shaft and hub from accelerated wear.
