Description

Full Technical Description

The 551 860 61 SEAL, BALL (55186061, 551-860-61, BALL JOINT 55186061) is a mining-grade articulation joint engineered for Sandvik drilling rigs, ROC series equipment, and underground jumbos. The 551 860 61 SEAL, BALL enables controlled rotational and angular movement within high-load linkage systems subjected to vibration, drilling shock, and continuous dynamic forces.

This 551 860 61 SEAL, BALL is built from hardened alloy steel with precision-machined spherical interfaces designed for minimal friction and long-term structural stability. Its sealed construction resists hydraulic oil, abrasive dust, moisture, and temperature fluctuation. OEM identifiers 55186061 and 551-860-61 ensure compatibility across Sandvik spare-parts catalogs.

Function & Operation

The 551 860 61 SEAL, BALL provides smooth articulation for feed assemblies, stabilizer mechanisms, actuator pivots, and mechanical linkages. Proper joint performance maintains drilling geometry, reduces stress on adjacent components, and supports long-term reliability in mining and tunneling operations.

Reliability & Maintenance

Inspect the 551 860 61 SEAL, BALL for spherical wear, corrosion, seat/boot damage, or excessive play. Replace 551 860 61 immediately if looseness, vibration noise, or misalignment develops.
