The Multiquip EM010009 Square Key 1/4 x 1/4 x 1 is a genuine OEM component designed for Essick Mixer equipment. This precisely dimensioned drive key ensures solid, slip-free power transmission between the shaft and hub, maintaining the torque transfer your mixer depends on during every batch. As a genuine Multiquip OEM part, EM010009 is manufactured to the exact specifications called out in the original equipment design, so you can install it with confidence. Confirmed fitment for Essick Mixer models in the EM120SM series.
Key Features
- Genuine OEM Tolerancing — Manufactured to exact dimensional specs for a shaft and keyway fit that transmits torque without slop or movement.
- Direct Drop-In Replacement — Matches the original 1/4 x 1/4 x 1 profile, seating cleanly into the existing keyway slot without alteration.
- Confirmed Essick Mixer Fitment — Verified for Essick Mixer EM120SM series equipment, taking the guesswork out of parts sourcing.
- Maintains Full Drum Drive Integrity — A worn or missing key allows the shaft to spin independently of the hub, causing erratic drum rotation or complete loss of mixing action; this part restores solid engagement.
- Corrosion-Resistant Construction — Hard key stock resists the wet, abrasive environment typical of concrete and mortar mixing operations.
A square key is a small but critical drive component that locks a rotating shaft to a hub, gear, or pulley, ensuring both parts turn together as a single unit. In a concrete or mortar mixer, the key sits in machined slots — the keyway — cut into both the shaft and the mating component, preventing any rotational slip under load. When a key shears or wears, the driven component stops turning even though the shaft continues to spin, resulting in lost mixing action and potential damage to surrounding components if the fault goes unaddressed.
