Application & Technical FAQ
What should be checked before installation?
+
-
Mounting surfaces, alignment accuracy, and cleanliness should be verified before installation to ensure stable operation and long service life.
What problems can occur if the bearing is not properly aligned?
+
-
Improper alignment may affect smooth rotation and lead to uneven load distribution. Accurate mounting is essential to maintain consistent performance.
How can vibration be controlled in precision equipment?
+
-
Stable mounting conditions, balanced rotating components, and correct installation torque help reduce vibration during operation.
What does abnormal torque indicate during operation?
+
-
Unstable torque may be related to improper installation, contamination, or inconsistent lubrication conditions within the system.
Does temperature affect bearing performance?
+
-
Yes. Temperature changes can influence internal clearance and operating stability. Proper lubrication and thermal control help maintain consistent performance.
