💡 How do sealed piloted flange ball bearings help reduce maintenance on industrial shafts? They keep grease in and grit out so shafts run longer between services. - Sealed ball bearing design with contact seal and slinger blocks contamination. - Relubrication port lets you top up grease for extended bearing life. - Set-screw locking and piloted 4-bolt flange keep shaft alignment handy and steady. - Cast iron housing handles heavy loads and up to 212°F operating temp.
