Multiquip 90745ZE2600 Square Key 6.3 x 6.3 x 43 mm

The Multiquip 90745ZE2600 Square Key 6.3 x 6.3 x 43 mm is a genuine OEM component designed for a wide range of Multiquip, Whiteman, and Essick equipment including WM70, WM90, MC64, MC94, EM70, EM90, EM120, and associated mixer and equipment series. As a direct OEM replacement, 90745ZE2600 is manufactured to the exact dimensional specification required for correct shaft-to-hub engagement across every compatible model. Sourced directly through authorized Multiquip supply channels, this key ensures the torque transfer connection between rotating shaft and driven component is maintained without play or slippage. DHS Equipment stocks this part ready for immediate order so you can keep your equipment running without extended delays.

Key Features

• Exact OEM Dimensions — Manufactured to the precise 6.3 x 6.3 x 43 mm profile required for correct keyway seating and full shaft contact across all compatible models.
• Genuine Multiquip OEM Part — Sourced through authorized Multiquip channels, this component meets the same material hardness and dimensional tolerances as the part it replaces.
• Broad Fitment Coverage — Compatible with WM70, WM90, WM63, WM120, MC64, MC94, MC12PH, EM70, EM90, EM120, PRO12, QP3TH, V305EH, R2000H, SP118, MP-series saws, and more.
• Positive Torque Transfer — A correctly sized square key locks the shaft and hub together under load; a worn, undersized, or sheared key causes slippage, vibration, and component damage that compounds quickly.
• Drop-In Installation — Fits directly into the existing keyway without machining or modification, allowing straightforward field or shop replacement.

A square key is a small but load-critical drivetrain component that sits in matching slots — called keyways — cut into both a rotating shaft and the hub of the component it drives, such as a drum sprocket, pulley, or impeller. By interlocking the two parts, the key transmits rotational force from the shaft to the driven component and prevents independent rotation under torque. When a key shears, deforms, or works loose, the driven component loses its positive drive connection, resulting in slippage, erratic operation, or complete loss of function in that drive circuit. Replacing a failed or worn key promptly with a dimensionally correct OEM part like the Multiquip 90745ZE2600 restores full torque transfer and prevents secondary damage to the keyway itself.
