Key Features
- Genuine OEM Construction: — Manufactured to the exact dimensional tolerances required for proper shaft and hub engagement in Essick mixer drive systems.
- Direct Drop-In Replacement: — Seats into the existing keyway without alteration, restoring the original mechanical connection between rotating components.
- Confirmed Fitment: — Compatible with Essick EM120SM and EM12M Series mixers; verify your model code before purchase to ensure an accurate match.
- Torque Transfer Integrity: — A correctly fitted sq key locks the drive shaft and driven component together, maintaining full torque transfer to the drum during mixing cycles.
- Wear-Driven Replacement: — A worn or sheared key causes slippage between the shaft and hub, leading to drum stall or erratic rotation; replacing it promptly restores consistent mixer output.
A sq key — or square key — is a small but critical drive component that fits into a machined slot (keyway) shared between a rotating shaft and the hub of a gear, pulley, or drum coupling. Its purpose is to lock these two components together so that rotational force (torque) is transmitted from one to the other without slipping. When a sq key shears, deforms, or works loose through vibration or overload, the driven component can spin independently of the shaft, causing the mixer drum to stall or lose power. Replacing a damaged key immediately restores the mechanical connection and prevents further damage to the shaft or hub surfaces.
