Full Description
2780-58M -- Metric-Specification BMW Center Support Bearing
The "M" suffix on the 2780-58M denotes a metric-specification assembly that aligns with BMW OEM part standards. While the bore ID is expressed as 1.378" (35 mm) and the center-to-base height as 1.325", all internal dimensions conform to ISO metric tolerance classes rather than the SAE fit classes used in domestic truck applications.
This distinction matters most for the inner race press fit. BMW specifies a K6 tolerance on the stub shaft journal (an interference fit) rather than the r6 used by some domestic suppliers. An SAE-tolerance shaft at the same nominal 35 mm dimension may be 0.003--0.006 mm undersize, resulting in insufficient interference for the center support bearing inner race -- leading to race spin and immediate failure.
BMW OEM cross-references in the 26 12 1 229 492 and 26 12 7 506 783 families apply to various 3-series and related platforms. Always confirm via chassis code and production date stamp from the removed bearing housing.
