💡 What is a sealed ball bearing used for in linear slide units? A sealed ball bearing keeps contaminants out and helps systems run smoother with less maintenance. - It reduces friction and supports radial and axial loads in linear slide unit and conveyor systems. - The sealed design protects against dust and moisture and lowers service intervals for heavy-load applications. - For higher-speed or low-weight requirements some systems use ceramic ball bearings; sealed steel bearings remain a reliable choice for most linear slides.
