The Bomag 05850471 Hydraulic Cylinder is a genuine OEM component designed for Bomag tandem rollers across the BW 141, BW 151, BW 154, BW 161, BW 190, BW 191, BW 202, and BW 206 series, including models BW 141 AD-5, BW 151 AD-5, BW 154 AD-5, BW 151 AD-5 AM, BW 151 AC-5, BW 141 AD-50. Sourced directly from Bomag, this hydraulic cylinder matches the original equipment specification, ensuring a correct drop-in fit with no guesswork. Verified by part number 05850471, this component is the right choice for operators and fleet managers who need dependable hydraulic performance restored quickly.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured by Bomag to the exact dimensional and pressure tolerances of the original cylinder, ensuring consistent hydraulic force delivery across the full stroke range
- Direct-Fit Replacement — engineered to the original mounting interface and port configuration, so this hydraulic cylinder installs directly into compatible BW-series tandem rollers without modification
- Broad Tandem Roller Coverage — fits an extensive range of Bomag tandem rollers including the BW 141 AD-5, BW 151 AD-5, BW 154 AD-5, BW 161 AD-5, BW 161 AC-5, BW 190 AD-5, BW 191 AD-5, BW 202 AD-5, BW 206 AD-5, and their AD-50, ADO-5, ADO-50, AC-50, and AM variants
- Steering and Articulation Reliability — a properly functioning hydraulic cylinder maintains precise steering response and articulation control, which is critical for accurate asphalt compaction passes and operator safety on live roadways
- Leak-Free Sealing Performance — built with OEM-grade internal seals and honed bore tolerances that resist pressure-induced leakage, preventing the hydraulic fluid loss that causes sluggish or unresponsive machine behavior
The hydraulic cylinder on a tandem roller is a core element of the machine's steering and articulation system. It converts hydraulic pressure from the machine's pump into the linear force needed to pivot the front and rear frames relative to each other, giving the operator precise directional control during compaction passes. When this cylinder develops internal leaks or seal failure, steering becomes slow, imprecise, or completely unresponsive — creating both a productivity loss and a serious safety concern on active paving sites. Replacing a worn or failed cylinder with a genuine OEM part restores full hydraulic authority and keeps the roller tracking accurately pass after pass.
