💡 What makes Si₃N₄ bearings superior in sensitive applications?
Silicon nitride is lighter, harder, and more temperature-resistant than steel - perfect for high-speed, high-cleanliness, and corrosive environments. The PTFE cage adds smooth motion and chemical resistance.

For advanced setups that demand ultra-clean performance - this 15-pack of 6203-2RS Si₃N₄ bearings is built to roll where others rust or fail!
