FeaturedBEARING BUSHING
550 356 04 BEARING BUSHING This is the material found inside the rock drilling bit. It is made of bronze and placed inside the steel. It is sandwiched between two steel pieces, protecting them from damage. It has oil channels within it. These channels allow the material to penetrate for extended periods. The constant movement of these channels causes oil to circulate throughout the bit. Therefore, the 55035604 BEARING BUSHING allows the drill to operate for longer periods.

Full Technical Description
The 550 356 04 BEARING BUSHING (also indicated as 55035604 and 550-356-04) is a mining-grade precision bushing engineered for Sandvik drilling rigs, ROC-series machinery, and underground jumbos. The 550 356 04 BEARING BUSHING ensures smooth, low-friction rotational support for shafts, feed mechanisms, gear drives, and drifter components exposed to vibration, radial loads, axial forces, and continuous drilling stress.
This 550 356 04 BEARING BUSHING is manufactured from reinforced bearing-grade alloy with precision-machined internal surfaces designed for optimal lubrication retention, wear resistance, and long service life in dusty, oil-exposed, and high-impact mining environments. OEM references 55035604 and 550-356-04 confirm full compatibility with Sandvik assemblies.
Function & Operation
The 550 356 04 BEARING BUSHING stabilizes rotating elements in drifters, feed drives, hydraulic motors, and gearbox units by reducing friction and maintaining precise shaft alignment. Proper bushing performance lowers heat generation, improves drilling accuracy, and helps prevent premature wear across critical components in mining and tunneling operations.
Reliability & Maintenance
Inspect the 550 356 04 BEARING BUSHING for scoring, corrosion, ovality, lubrication loss, or unusual noise. Replace 550 356 04 immediately if rotational instability or vibration increases.
