Description

Full Technical Description

The CARTRIDGE 551 746 76 (also indicated as 55174676 and 551-746-76) is a precision-engineered CARTRIDE used in hydraulic, pneumatic, or fluid-control systems on Sandvik drilling rigs, ROC-series platforms, and underground jumbos. The 551 746 76 CARTRIDGE ensures controlled flow, stable pressure regulation, and contamination protection for critical drilling and actuation systems operating in severe mining conditions.

This 551 746 76 CARTRIDGE is manufactured from high-strength, corrosion-resistant materials with tight machining tolerances to maintain sealing integrity despite vibration, pressure cycling, hydraulic oil exposure, and rock-dust ingress. OEM identifiers 55174676 and 551-746-76 confirm full compatibility with factory-installed Sandvik components.

Function & Operation

The 551 746 76 CARTRIDGE performs internal filtration, metering, or pressure control depending on subsystem configuration. It stabilizes hydraulic or pneumatic behavior, supports accurate drilling response, and prevents internal wear caused by contamination and pressure spikes.

Reliability & Maintenance

Inspect the 551 746 76 CARTRIDGE for seal wear, housing scoring, clogging, or leakage. Replace 551 746 76 immediately if pressure fluctuations, slow response, or contamination alerts occur.
