💡 What is a shaft oil seal used for in linear slide units and sealed bearings? A shaft oil seal keeps lubricant in and keeps dirt and water out so bearings and slides last longer. Here’s a quick breakdown of why it’s handy: - Protects sealed ball bearing performance by preventing lubricant loss and contamination - Improves linear slide unit reliability by blocking dust, debris, and moisture at the shaft interface - Reduces shaft and housing wear to extend service intervals and lower maintenance needs
