Multiquip EM189 Spacer 0.75" OD x 0.38" ID x 0.188"

The Multiquip EM189 Spacer 0.75" OD x 0.38" ID x 0.188" is a genuine OEM spacer designed for a broad range of Multiquip and Whiteman equipment, including CA4HM walk-behind trowels, HTNS5S-2 and JTO-Series ride-on trowels, WM45H, WM45HE, and WM45HCE Whiteman mixers, QPT205SLT and QP205SLT centrifugal pumps, and international trowel models such as JTNS20, JTNSW20, JTNSW24HTCSL, and JTNSW20HTCSL. As a direct Multiquip OEM part, EM189 is manufactured to the exact dimensional specification required to maintain proper component alignment and clearance across each compatible machine. Sourcing the correct spacer by EM189 is critical — even minor dimensional variation can lead to misalignment, accelerated wear, or assembly failure.

Key Features

• Exact OEM Dimensions — Manufactured to precise 0.75" OD, 0.38" ID, and 0.188" thickness tolerances, ensuring the correct standoff and clearance within the assembly.
• Genuine Multiquip OEM Part — Sourced directly from Multiquip, this spacer meets the same material and dimensional standards as the original component installed at the factory.
• Broad Cross-Equipment Fitment — Confirmed fit across CA4HM, WM45H series mixers, HTNS5S-2, JTO-Series, JTNS20, JTNSW20, and JTNSW24HTCSL trowels, plus QPT205SLT and QP205SLT pumps.
• Preserves Component Alignment — A correctly sized spacer maintains the intended gap and load distribution between mating parts, protecting surrounding components from premature wear.
• Direct Drop-In Replacement — Designed to install in the same position as the original, with no machining or modification needed to achieve proper fit.

A spacer is a precision-dimensioned component used to maintain a fixed gap, set bearing preload, or establish correct axial or radial positioning between two mating parts in an assembly. When the spacer is the wrong size — even fractionally — it can allow unwanted movement, uneven load distribution, or contact between parts that should remain separated, leading to accelerated wear on bearings, shafts, or housings. Using the correct OEM spacer, like the Multiquip EM189, ensures that every connected component in the assembly operates within its intended range of motion and contact pressure.
