💡 Why is C3 clearance used in deep groove ball bearings for motors and machinery?
C3 clearance bearings are used when operating conditions cause heat buildup or higher shaft speeds.

• Extra internal clearance allows for thermal expansion during operation

• Helps prevent preload and overheating at higher RPM

• Supports smoother rotation and longer bearing life in demanding setups

This Nachi bearing is a handy choice when you want quiet operation, strong load handling, and dependable performance in industrial and motor driven applications.
