How often to replace FY-50Y lift cable (FY50-09.02)?

Replace every 3,000 operating hours or immediately if 3+ broken wires per strand (per GB/T 20118-2017 standard).

Why do NBR O-rings fail prematurely?

Common causes: incompatible oil, over-compression (＞20%), or fluid temperature exceeding 80℃. Use NBR-compatible oil and control compression ratio.
