What is an acceptable tolerance of unbalance?

Answer 1

An acceptable tolerance of unbalance typically depends on the specific application and industry standards. Generally, for rotating machinery, an unbalance of 1% to 2% of the rotor's mass is considered acceptable for most applications, while more precise operations may require tolerances as low as 0.1%. In critical applications, such as aerospace or high-speed machinery, even tighter tolerances may be necessary to ensure safety and performance. Always refer to manufacturer guidelines or industry standards for specific tolerance requirements.
