Key Features
- Genuine OEM Specification: — Produced to exact Multiquip dimensional tolerances for consistent shaft-to-hub torque transfer without slippage or play.
- Correct 3/8 x 3/8 x 1-3/4 Profile: — Drop-in replacement sized to match the original keyway geometry on EM900SD and EM120SM mixer shafts exactly as engineered.
- Confirmed Fitment: — Verified for Essick Mixer models EM900SD and EM120SM; reference part number EM010022 when ordering to confirm application.
- Positive Power Transmission: — A correctly fitted square key locks the driven component firmly to the shaft, maintaining consistent drum rotation and mix quality under load.
- Compact, High-Stress Component: — Square keys bear significant shear forces during operation; using the OEM-specified material grade ensures the key shears predictably under overload rather than damaging the shaft or hub.
A square key is a small but critical power-transmission component that sits in a machined slot between a rotating shaft and a hub — such as a sprocket, pulley, or gear — locking them together so torque is transferred without slippage. On concrete and mortar mixers like the EM900SD and EM120SM, the key keeps the drum drive components positively engaged with the driveshaft throughout the mixing cycle. When a key wears, shears, or goes missing, the driven component spins freely on the shaft, resulting in loss of drum rotation and an immediate work stoppage until the key is replaced.
