Cement Mixer bearings are specially designed spherical roller bearings for concrete mixer truck drum support applications. These bearings feature C3 radial internal clearance to accommodate thermal expansion during operation, and are manufactured with enhanced surface finish and special heat treatment for reliable performance under the heavy, shock-loaded conditions typical in concrete transport. The 22200 series base design provides excellent load distribution and misalignment accommodation, making them the industry standard for mixer drum support bearings.
