What It Is / How It Works

These miniature deep groove bearings are small rolling-element bearings that sit on a shaft and let it turn with low friction. Deep groove is the design most widely used in small rotating parts, and it is a common choice for compact mechanisms such as small RC car and skate-style builds.

Who It's For / Use Cases

Hobbyists who build or repair small RC car parts often need a bearing that matches a small shaft exactly. Anyone sourcing small deep groove bearings for compact mechanisms will also find this type useful when a sealed, grease-lubricated unit is wanted.

How to Use / Care

1. Fit the bearing onto a shaft in a miniature RC car part, with the inner diameter matched to that shaft.

How to Choose

Start with the inner diameter, since it must match the shaft it sits on. It comes in inner diameters of 2mm, 3mm, 4mm, 5mm, 6mm and 7mm, and the size range runs from 1mm to 12mm. Grease lubrication and metal seals on both sides are useful points to compare when choosing among small bearings.
