A very light lubricant, or none, used to let a bearing spin as freely as possible.
What it is
In the spinner world, running dry means a bearing has been cleaned of thick grease and left with little or very thin lubricant. Some players use dry-film products; others run bearings with none.
Why it matters
Dry setups spin longer and sound louder, but wear faster and are less protected from dust and moisture. Heavier lube spins shorter and quieter but lasts longer.
Also known as: Dry Lubricant, Thin Lube, 干式润滑.
是什么
在陀螺圈里，“干跑”指轴承清掉了厚油脂，只留很少或很稀的润滑，有人用干膜润滑剂，有人完全不加。
为什么重要
干式润滑转得更久、声音更响，但磨损更快，对灰尘和湿气的保护也更少。较稠的润滑转得短、更安静，但更耐用。
又称：Dry Lubricant、Thin Lube、干式润滑。
