ACCUMULATOR

The 550 117 63C ACCUMULATOR (55011763c, 550-117-63c, ACCUMULATOR 55011763c) is a high-pressure hydraulic ACCUMULATOR block engineered for Sandvik drilling rigs. Designed for mining and tunneling duty, the 550 117 63C ACCUMULATOR stores and releases hydraulic energy to stabilize system pressure under rapidly changing drilling loads.

This 550 117 63C ACCUMULATOR absorbs and moderates hydraulic shock loads generated by feed cylinders, rotation drives, and impact systems. By damping pressure spikes, 55011763c protects pumps, seals, hoses, and valve assemblies from cavitation, vibration, over-pressurization, and machine-oil aeration. The identifiers 55011763c and 550-117-63c are commonly used catalog variations for the same assembly.

The 550 117 63C ACCUMULATOR maintains consistent hydraulic delivery to rotation, percussion, and feed systems, improving drilling accuracy, penetration rate, and equipment smoothness. Stable ACCUMULATOR response minimizes system fatigue and contributes to longer component life in harsh mining environments.

Inspect the 550 117 63C ACCUMULATOR for nitrogen loss, shell fatigue, leakage, or diminished damping performance. Replace 55011763c immediately if pulsation increases or ACCUMULATOR response becomes delayed. Follow OEM nitrogen precharge specifications and hydraulic bleeding procedures for correct installation.

Also indicated as 55011763c, 550-117-63c, and ACCUMULATOR 55011763c, this hydraulic ACCUMULATOR block is widely chosen for OEM-standard performance and good-price replacement options for Sandvik machinery.
