Designed to balance protection and smooth rotation, the 3RB-R1038-ZZ/2 double metal shield bearings are a practical upgrade for many RC setups. Their 3/8 x 5/8 x 5/32 inch dimensions make them a common fit for wheels and driveline components where sealed performance is preferred.
With metal shields on both sides, these bearings keep contaminants out and lubricant in, helping parts last longer between services.
The pair installs into common hubs and assemblies without special tooling in most cases, simplifying routine maintenance and upgrades.
