Multiquip EM903092 Bearing Assembly C30HD - OEM Replacement Part

The bearing assembly is a critical wear component in the pumping mechanism of Multiquip C30HD series concrete pumps, supporting the reciprocating piston system that enables pumping rates up to 25 cubic yards per hour. This assembly operates within the splash-lubricated gearbox containing 7 gallons of SAE 30 motor oil, enduring continuous stress during concrete pumping operations with vertical heights up to 150 feet and horizontal distances of 400-500 feet. Regular inspection of bearing condition is essential during lubrication box maintenance checks, as bearing wear can lead to increased vibration, reduced pumping efficiency, and potential damage to the reciprocating piston assembly.

This genuine OEM bearing assembly is engineered specifically for the demanding environment of trailer-mounted concrete pumps handling aggregate sizes up to 1/2 inch minus (12.7mm). Proper bearing function is critical for maintaining the pump's rated capacity and protecting the enclosed lubrication system from contamination or failure.

Compatible with the following Multiquip concrete pump models:

• C30HDN
• C30HDNI
• C30HDZ
