The Bomag 05803091 Spacer Ring is a genuine OEM component designed for MPH 121, MPH 122, and MPH 122-2 recyclers/stabilizers. Sourced directly from Bomag, this spacer ring delivers the exact dimensional tolerances required to maintain correct component alignment and spacing within the drivetrain or rotor assembly. Confirmed fitment across the MPH 121, MPH 122, and MPH 122-2 means you can order with confidence that part number 05803091 will install without modification.
Key Features
- Genuine OEM Dimensional Accuracy — manufactured to Bomag's exact thickness and bore tolerances, ensuring proper load distribution and component spacing that a loose-tolerance substitute cannot guarantee
- Direct OEM Replacement — matches the original mounting interface on MPH-series recyclers/stabilizers, dropping into position exactly as the factory-installed ring did
- Confirmed Fitment — verified for the MPH 121, MPH 122, and MPH 122-2 recyclers/stabilizers, covering the full MPH 120-series production range
- Protects Adjacent Components — a correctly sized spacer ring prevents unwanted axial movement that can accelerate bearing wear, shaft damage, or rotor misalignment on high-demand stabilizer applications
- Genuine Bomag OEM Part — part number 05803091 is an authentic Bomag replacement, ensuring material grade and geometry match the original specification for the service life the machine demands
A spacer ring is a precision-machined component used to set and maintain the correct axial gap between rotating or fixed parts — such as bearings, shafts, gears, or rotor assemblies. By holding components at the designed separation distance, it prevents unwanted contact, controls preload, and ensures even load transfer across mating surfaces. When a spacer ring wears, cracks, or is installed at the wrong dimension, adjacent components begin to shift or run out of true, leading to accelerated wear on bearings, seals, and shafts and ultimately causing more extensive mechanical failure in the machine.
