For RC builders looking to shave grams from spinning parts, the Tamiya 555015 - RC 1150 plastic bearings work well in 1/10 scale cars. The plastic design gives a lighter option while still supporting wheels and other moving components.
The bearings are crafted to reduce unnecessary mass around axles and hubs, improving agility and throttle response. Their common 1150 dimension makes them a practical swap for many kits.
Compared with metal bearings, these plastic units need less frequent lubrication and are straightforward to fit, which is handy when you need a quick change between runs.
