The Multiquip EM26113 is a genuine OEM Key 3/16 Square x 2-1/4 designed for ST-70 submersible pumps and WSHE-A Series vibratory screeds. As a direct OEM replacement, EM26113 matches the original manufacturing specification — ensuring the key seats correctly in the keyway and maintains the precise shaft-to-hub engagement the machine requires. Sourced directly through authorized Multiquip channels, this part carries the same quality backing as the original component that left the factory.
Key Features
- OEM-Matched Dimensions — Cut to exact 3/16 square profile and 2-1/4 length, so the key fills the keyway fully without slop or rocking that could damage mating surfaces.
- Genuine Multiquip Part — Sourced through the official Multiquip OEM supply chain, confirming correct material grade and hardness for this drive application.
- Drop-In Shaft Fit — Engineered to align shaft and hub without shimming, filing, or secondary fitting — seats cleanly on first installation.
- Verified Fitment — Confirmed for ST-70 submersible pumps and WSHE-A Series vibratory screeds; always cross-reference your model and serial number before ordering.
- Torque Transfer Integrity — A correctly sized key locks the rotating assembly so power transfers cleanly from shaft to driven component; an undersized or worn key allows slippage that rapidly damages both the shaft and the hub bore.
A shaft key is a small but load-critical component that sits in a machined slot — the keyway — shared between a rotating shaft and a hub, pulley, or impeller. Its job is to lock the two parts rotationally so that torque passes from one to the other without slipping. When a key is worn, sheared, or missing, the shaft spins independently inside the hub, causing immediate loss of drive and progressive wear to the keyway walls that can make shaft replacement necessary. Keeping a correctly sized OEM key in place protects the surrounding components and maintains full drive efficiency.
