ADJUSTING SCREW

The 159 291 08 ADJUSTING SCREW (15929108, 159-291-08, ADJUSTING SCREW 15929108) is a precision-machined adjustment component used throughout Sandvik drilling systems. Engineered for continuous vibration, hydraulic shock, and mechanical loading, the 159 291 08 ADJUSTING SCREW enables fine alignment and preload adjustment of critical assemblies in mining and tunneling machinery.

This 159 291 08 ADJUSTING SCREW provides stable, repeatable positioning for hydraulic blocks, valve interfaces, mechanical linkages, and mounting structures on jumbos and ROC rigs. OEM references 15929108 and 159-291-08 correspond to the same high-quality part used across Sandvik documentation.

The 159 291 08 ADJUSTING SCREW maintains component alignment, compensates for wear, and preserves hydraulic or structural calibration. This supports drilling accuracy, reduces vibration-induced fatigue, and improves long-term reliability of feed beams, rotation units, and manifold assemblies. It is a critical spare part to buy for preventive maintenance on mining and tunneling equipment.

Inspect the 159 291 08 ADJUSTING SCREW for thread damage, surface wear, corrosion, or deformation. Replace immediately if adjustment travel decreases or if backlash develops in connected components.

Also indicated as 15929108, 159-291-08, and ADJUSTING SCREW 15929108, this ADJUSTING SCREW is compatible with a wide range of Sandvik equipment requiring accurate mechanical tuning.
