💡 What is a sealed ball bearing used for in heavy-load linear slide units? Sealed ball bearings keep lubricant in and harmful debris out so the mechanism runs smoother and lasts longer. Quick overview of typical benefits: - Retains lubricant and blocks contamination for lower maintenance in sealed ball bearing setups - Supports radial and axial loads found in linear slide units and compact drives - Handles higher temps (this steel design to 120°C); ceramic options exist for lower friction or higher speeds
