+Technical Breakdown of the Name: 6201-2RS
10
+
11
+- 6: Indicates a Deep Groove Ball Bearing (the most common type).
12
+- 2: Represents the Series (Light series; provides a balance between size and load capacity).
13
+- 01: This is the Bore Code. For codes 01, 02, and 03, the sizes are fixed:
14
+- 00 = 10mm
15
+- 01 = 12mm
16
+- 02 = 15mm
17
+- 2RS: Stands for Two Rubber Seals.
18

19
+`Pro-tip`: If you see ZZ, it means metal shields. For an electric scooter (outdoor use), 2RS is superior because it keeps water and grime out of the internal grease.
20
+
21
+`Axle Fit`: Ensure your axle is exactly 12mm. If the axle is slightly undersized (e.g., 11.8mm), you may experience "play" or wobbling.
22
+
23
+`Hub Housing`: The hole in your wheel hub must be machined to 32mm. This is usually a "press-fit," meaning it should be tight enough that you need a tool or a rubber mallet to seat it.
