FeaturedBEARING BUSHING
207 974 08 BUSHING, BEARING 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 20797408 BEARING BUSHING allows the drill to operate for longer periods.

Full Technical Description
The 207 974 08 BUSHING, BEARING (also indicated as 20797408 and 207-974-08) is a mining-grade precision bushing engineered for Sandvik drilling rigs, ROC-series machinery, and underground jumbos. The 207 974 08 BUSHING, BEARING 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 207 974 08 BUSHING, BEARING 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 20797408 and 207-974-08 confirm full compatibility with Sandvik assemblies.
Function & Operation
The 207 974 08 BUSHING, BEARING 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 207 974 08 BUSHING, BEARING for scoring, corrosion, ovality, lubrication loss, or unusual noise. Replace 207 974 08 immediately if rotational instability or vibration increases.
