The Multiquip EM903049 Bearing Cone is a genuine OEM component designed for MC, EC, WC, CMS, EM, and WM series concrete and mortar mixers. This direct-replacement bearing cone is sourced from Multiquip and is confirmed to fit a wide range of drum mixer models including MC-42S, EC-42S, EC-62S, EC-62P, EC-92S, EC-92P, MC-62S, MC-62P, MC-92S, MC-92P, CMS-4S, CMS6S, CMS-9, WC-42S, WC-62S, WC-62P, WC-92S, WC-92P, EM-700S, EM-700P, EM-900S, EM-900P, WM-700S, WM-700P, WM-900S, and WM-900P. As a genuine OEM part, EM903049 meets the original design tolerances and load ratings specified for these machines. Keeping this bearing in serviceable condition is essential to smooth drum rotation and consistent mix quality on the job.
Key Features
- OEM-Grade Tapered Bearing Tolerancing — Manufactured to the original load-rating and taper-angle specifications, ensuring the cone seats correctly against its matched cup under drum rotation forces.
- Drop-In Drum Axle Replacement — Engineered to seat directly onto the drum axle journal of compatible MC, EC, WC, CMS, EM, and WM mixer models without modification to the bearing housing or spindle.
- Broad Mixer Family Coverage — A single part number covers steel and poly drum variants across the MC, EC, WC, CMS, EM, and WM series, from 42-class through 92-class concrete mixers and 700- through 900-class mortar and plaster mixers.
- Sustained Drum Rotation Integrity — A correctly seated bearing cone supports consistent drum speed and smooth rotation; a worn or failed cone introduces drum wobble, uneven mixing, and accelerated wear on adjacent components.
- Genuine Multiquip OEM Part — Supplied directly from the Multiquip parts network, so part number this part matches current factory documentation for all listed models.
A bearing cone is the inner race of a tapered roller bearing assembly — it fits over the axle shaft and works in combination with the outer cup to carry the radial and axial loads generated as the mixer drum rotates under load. In a drum mixer, this bearing supports the full weight and motion of the rotating drum and its contents, so proper seating and lubrication are critical. When a bearing cone wears, develops flat spots, or loses its surface finish, drum rotation becomes rough and uneven, noise increases, and the load transfers unevenly to the axle and housing — eventually leading to drum wobble or bearing seizure that takes the machine out of service.
