2880-55 – Center Support Bearing – Mercedes Application – 1.181″ ID – 2.375″ Center Bearing To Base

2880-55 vs. 2880-56
Both: Mercedes application  |  Bore ID: 1.181" (30 mm)  |  Height: 2.375"  |  Distinguish by: Mercedes OEM part number from the removed center support bearing

The 2880-55 and 2880-56 are dimensional twins -- same bore, same height -- serving different Mercedes model variants or production year configurations. This is a recurring pattern in the Mercedes 2880 series: multiple SKUs with identical bore and height but different bracket geometries for specific chassis applications.

The most reliable identification approach for these dimensional twins: record the Mercedes-Benz OEM part number printed on the bracket casting of the removed bearing. This number is typically found on a small metal tag pressed into the bracket arm or stamped directly into the bracket casting. If the number is absent or unreadable due to corrosion, contact a Mercedes parts supplier with the vehicle VIN and request the OEM propshaft center bearing number before ordering. Mercedes OEM references for 30 mm bore, 2.375" height units span several series depending on model; the 2880-55 and 2880-56 SKUs correspond to different series numbers within that range.
