The Bomag 05850452 Spherical Plain Bearing is a genuine OEM component designed for BC 972 RB-3, BC 972 RB-4, BC 1172 RB-3, and BC 1172 RB-4 refuse and landfill compactors. Sourced directly from Bomag, this bearing matches the original specification and slots into place without modification to surrounding hardware. It is the correct service replacement for keeping articulation points, linkages, and pivot joints operating within design tolerances on these high-cycle machines.
Key Features
- OEM-Grade Angular Misalignment Capacity — manufactured to Bomag's original tolerancing, this bearing maintains its rated load capacity and misalignment range across the full compaction cycle, where lesser bearings crack or seize prematurely.
- Drop-In Fitment for BC-Series Refuse Compactors — dimensioned to match the original housing bore and shaft diameter, this spherical plain bearing installs directly into the same pivot or linkage seat as the factory part.
- Confirmed Compatibility — fits BC 972 RB-3, BC 972 RB-4, BC 1172 RB-3, and BC 1172 RB-4 refuse and landfill compactors as a verified OEM replacement.
- Sustained Articulation Under Load — a correctly functioning spherical plain bearing allows the compactor's joints and linkages to pivot freely under heavy compaction loads; a worn bearing introduces play, accelerates wear on adjacent components, and compromises steering and frame articulation.
- Genuine Bomag Part — supplied as an authentic Bomag component under part number 05850452, ensuring material grade, surface finish, and dimensional accuracy align with the original assembly.
A spherical plain bearing is a sliding-contact bearing that accommodates both rotational movement and angular misalignment between two connected components. On refuse and landfill compactors like the BC 972 and BC 1172 series, these bearings are used at high-load articulation points — such as steering linkages, boom pivots, and frame joints — where misalignment and shock loading are constant. When a spherical plain bearing wears out, the joint develops looseness that translates into imprecise steering, abnormal stress on pins and bores, and accelerated damage to the surrounding structure. Replacing a failed bearing promptly with the correct OEM part restores proper joint geometry and protects the integrity of the compactor's articulation system.
