Q: How do I know when the WM LB5004 needs replacement?
A: Replace the WM LB5004 bearing cup when you observe grinding or clicking sounds during mast operation, lateral mast wobble, or rough bearing movement. A worn bearing cup creates excessive internal play and reduces lifting precision and safety.
Q: What is the service life expectancy of the WM LB5004?
A: Under typical electric truck duty cycles, the WM LB5004 bearing cup lasts 4-7 years depending on load frequency, equipment maintenance, operating environment, and temperature conditions. Heavy-duty or outdoor operation may reduce lifespan.
