The Multiquip EM903012 is a genuine OEM Axle Up Bearing designed for a wide range of Multiquip, Whiteman, and Essick mixer and power buggy equipment, including WM70, WM90, MC94, MC64, WM120, EM70, EM90, EM120, WBH-16, and WBH-21 series models. As a direct OEM replacement, EM903012 is manufactured to the same specifications as the original component, ensuring a correct fit without guesswork. DHS Equipment supplies this part backed by Multiquip's genuine OEM supply chain, so you're getting the exact bearing your machine was built with. Confirm your model against the fitment list before ordering to ensure compatibility.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original bearing tolerances, delivering the same load capacity and rotational precision as the factory-installed component.
- Broad Cross-Family Fitment — Compatible with WM70, WM90, WM120, MC44, MC64, MC94, EM70, EM90, EM120, WBH-16, WBH-21, and select Mayco C30HD concrete pump models.
- Drop-In Axle Position Fit — Engineered to seat correctly in the upper axle position, matching the original bore dimensions and load orientation for a clean installation.
- Supports Consistent Drum and Drive Performance — A properly functioning axle bearing keeps drum rotation smooth and drive loads properly distributed; a worn bearing causes vibration, uneven wear, and eventual axle damage.
- Verified Part Number — Order with confidence using part number EM903012, cross-referenced directly against Multiquip OEM parts documentation.
The axle up bearing supports the upper axle position within the drivetrain or drum assembly of mixer and power buggy equipment, absorbing radial and axial loads generated during operation. It allows the axle to rotate freely and consistently, which is critical for smooth drum movement on mixers and reliable wheel or drive performance on power buggies. When this bearing wears or fails, operators typically notice increased vibration, noise at the axle, irregular drum rotation, or accelerated wear on surrounding drivetrain components — making timely replacement essential to protecting the broader assembly.
