💡 What is a sealed ball bearing used for in high-temperature flange mounts? Sealed ball bearings keep lubrication in and contamination out while handling rotational loads in hot environments. Short intro: they make maintenance easier and extend service life in demanding conditions. - Ideal for conveyor rollers, linear slide units, blower and fan housings where temps reach high levels and contamination is present - Silicone contact seals and a slinger provide dust exclusion and allow periodic relubrication for longevity - Set-screw locking and a cast iron 3-bolt flange housing simplify shaft mounting and replacement
