Hello everyone! What is the difference between single row bearing and double row bearing in rolling bearing? thank you

The "rolling bearing" you mentioned is a very big category.

Bearings are divided into two categories, one is sliding bearing and the other is rolling bearing. Rolling bearing is optimized by sliding bearing, which turns friction into rolling, that is, rolling bearing now.

In fact, it's easy to understand, just like we said single row and double row, just like queuing, one team and two teams, one of which is single row and double row.

The difference between the two is very obvious. The fundamental difference is that a single row has only one raceway with steel balls in it, while a double row has two raceways and two rows of steel balls. The inner diameter is almost the same, and the height of single row and double row is completely different.

Specifically, you can see the picture:
