💡 What is a non-standard ball bearing and when should I use it?

A non-standard bearing fills gaps where standard sizes won't fit. It’s handy for setups that require a precise fit without modifying housings and can be used in gearboxes, wheels, or custom hardware projects. This type of bearing handles high RPM and tough wear thanks to chrome steel, and the rubber seals keep out dirt to extend life. It’s a solid choice when the size isn’t typical but you still need reliable performance.
