SK55SR‑5 Center Joint Seal Kit Description

The YNF17394 YJ19H00002F1K SK55SR‑5 Center Joint Seal Kit contains all necessary sealing components to rebuild the hydraulic swivel joint of the SK55SR‑5 excavator. Over time, center joint seals can deteriorate due to continuous rotation, high pressure, and oil contamination, causing internal leakage, reduced hydraulic efficiency, or abnormal noise during machine operation.

This kit includes premium O-rings, dust seals, wear rings, gasket seals, and pressure-resistant backup rings made of PU, NBR, PTFE, and durable rubber compounds. These materials ensure long-lasting performance and reliable sealing under high-pressure and high-temperature conditions.

Ideal for service workshops, fleet operators, and aftermarket distributors, the YNF17394 seal kit restores hydraulic flow, stabilizes swivel joint performance, minimizes machine downtime, and prolongs the lifespan of excavator hydraulic systems.
