Bomag 05900587 Thrust Ring

The Bomag 05900587 Thrust Ring is a genuine OEM component designed for Bomag BM1000/30-2, BM1200/30-2, BM1200/30-T3, BM1300/30-2, and BM1300/30-T3 cold milling machines. Sourced directly from Bomag, this thrust ring delivers the exact tolerances and material grade required to maintain correct axial load management within the drivetrain assembly. Verified fitment across the BM1000, BM1200, and BM1300 cold milling machine families makes this the dependable choice when replacing a worn or damaged ring.

Key Features

• OEM-Grade Axial Load Control — manufactured to Bomag's original specification, this thrust ring provides the precise hardness and surface finish needed to handle the continuous axial forces generated in cold milling machine drivetrains
• Direct Drop-In Replacement — engineered to the original dimensional profile, this part seats and aligns exactly as the factory component did, with no reworking of adjacent hardware
• Broad Cold Milling Machine Coverage — confirmed fit for BM1000/30-2, BM1200/30-2, BM1200/30-T3, BM1300/30-2, and BM1300/30-T3 cold milling machines, spanning multiple generations and variants of the BM series
• Protects Bearing and Shaft Integrity — a correctly functioning thrust ring prevents damaging metal-to-metal contact between rotating and stationary components, preserving shaft shoulders and adjacent bearings from accelerated wear
• Genuine Bomag Part — part number 05900587 is an authentic Bomag OEM component, ensuring traceability and consistency with the original equipment build standard

A thrust ring is a hardened collar that sits between rotating and stationary drivetrain components to absorb and control axial (end-thrust) loads. In a cold milling machine, the cutter drum and its supporting drive components generate significant thrust forces during operation, and the thrust ring transfers those forces safely into the housing rather than allowing them to bear directly on bearings or shaft shoulders. When a thrust ring wears thin or cracks, axial play increases, bearing surfaces become overloaded, and drivetrain components can suffer rapid, costly damage — making timely replacement essential to keeping the milling drum running true.
