ADJUSTING SCREW

The 550 784 73 SCREW, ADJUSTING (55078473, 550-784-73, ADJUSTING SCREW 55078473) is a precision-machined adjustment component used throughout Sandvik drilling systems. Engineered for continuous vibration, hydraulic shock, and mechanical loading, the 550 784 73 SCREW, ADJUSTING enables fine alignment and preload adjustment of critical assemblies in mining and tunneling machinery.

This 550 784 73 SCREW, ADJUSTING provides stable, repeatable positioning for hydraulic blocks, valve interfaces, mechanical linkages, and mounting structures on jumbos and ROC rigs. OEM references 55078473 and 550-784-73 correspond to the same high-quality part used across Sandvik documentation.

The 550 784 73 SCREW, ADJUSTING 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 550 784 73 SCREW, ADJUSTING for thread damage, surface wear, corrosion, or deformation. Replace immediately if adjustment travel decreases or if backlash develops in connected components.

Also indicated as 55078473, 550-784-73, and ADJUSTING SCREW 55078473, this ADJUSTING SCREW is compatible with a wide range of Sandvik equipment requiring accurate mechanical tuning.
