The bearing block is a structural support component within the concrete pump's drive assembly, providing a fixed housing that locates and supports the rotating or reciprocating shaft under operational load. In a cycloidal-drive concrete pump like the C30HD series, the bearing block absorbs the significant radial and axial forces generated during the pumping cycle, keeping the shaft running true and protecting surrounding components from misalignment wear. When the bearing block is worn, cracked, or improperly seated, shaft deflection increases, leading to accelerated bearing failure, seal leaks, and loss of pumping efficiency.
