The Bomag 05585783 Brake Cylinder is a genuine OEM replacement designed for BW 172 D-2 and BW 142 D-2 single drum rollers. Sourced directly from Bomag, this brake cylinder matches the original component in every dimension and specification, ensuring it integrates seamlessly into the brake system without modification. This part is confirmed to fit BW 172 D-2 and BW 142 D-2 single drum rollers, making it the correct choice for operators maintaining these machines to OEM standard.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's original pressure ratings and bore tolerances, so the brake cylinder delivers consistent, predictable hydraulic actuation every time
- Exact-Match Replacement — identical porting, thread dimensions, and mounting geometry to the original unit, allowing straightforward installation in the existing brake circuit
- Confirmed Fitment — compatible with BW 172 D-2 and BW 142 D-2 single drum rollers under part number 05585783
- Sustained Stopping Power — a correctly functioning brake cylinder maintains full hydraulic pressure to the brake assembly, supporting the stopping force these single drum rollers require on grade and during maneuvering
- Critical Safety Component — the brake cylinder is a primary element of the machine's braking system; using a genuine OEM unit ensures the system operates within Bomag's designed safety parameters and holds up under repeated load cycles
The brake cylinder is the hydraulic actuator at the heart of the machine's braking system. When the operator applies the brake, hydraulic pressure enters the cylinder and forces a piston outward, engaging the brake mechanism to slow or hold the drum roller in place. A worn or leaking brake cylinder causes a loss of hydraulic pressure, resulting in soft, sluggish, or completely ineffective braking — a serious safety risk, particularly when operating on slopes or in confined worksites. Replacing a failed cylinder promptly with a correctly specified OEM part restores full brake response and keeps the machine operating safely.
