💡 Why use a plastic radial bearing with glass balls instead of a metal bearing?
Non-metal bearings avoid corrosion and stay smooth where moisture or chemicals are present.

• Helps reduce noise in light-duty mechanisms

• Performs well without lubrication in many environments

• Supports stable rotation in applications where metal bearings would fail

A clean, lightweight, handy solution when you need smooth motion without the downsides of metal.
