Full Technical Description
The 138 231 88 JAW PLATE (13823188, 138-231-88, ARM 13823188) is a mining-grade structural ARM engineered for Sandvik drilling rigs, ROC series machinery, and underground jumbos. The 138 231 88 JAW PLATE supports mechanical linkages, hydraulic drives, and feed assemblies exposed to extreme vibration, drilling shock, and heavy-load operating conditions.
This 138 231 88 JAW PLATE is manufactured from reinforced, high-strength steel with precision-machined interfaces to ensure stable mounting, accurate alignment, and long-term durability. Catalog identifiers 13823188 and 138-231-88 are widely referenced in OEM and aftermarket spare parts listings.
Function & Operation
The 138 231 88 JAW PLATE provides critical structural support and alignment within drilling assemblies, linking moving components such as boom joints, feed mechanisms, stabilizers, and actuators. Proper ARM rigidity improves drilling accuracy, minimizes mechanical wear, and maintains correct geometry under harsh mining and tunneling loads.
Reliability & Maintenance
Inspect the 138 231 88 JAW PLATE for cracking, deformation, weld fatigue, surface wear, or worn pivot interfaces. Replace immediately if any structural weakness is detected.
