💡 What causes caster wheels to squeak and fail prematurely?

• Dirt and moisture infiltrate exposed joints until internal balls crumble and seize.
• Sealed designs block debris while keeping grease trapped for extended service life.
• Cleaner pivot areas prevent grime buildup that accelerates wear on axles daily.
• Proper bearing swaps eliminate wandering steering issues during tight turning maneuvers.
