Technical Performance

The Radient 12x18x4mm rubber sealed bearings are precision-engineered components designed to meet the demanding requirements of RC vehicle operation. The outer diameter of 18mm and width of 4mm ensure these bearings fit precisely into mounting points specified for this size, whilst the rubber sealing provides a crucial barrier against environmental contaminants. The sealed design is particularly important for RC vehicles used outdoors on UK terrain, where exposure to moisture, dirt and debris is inevitable. Unlike open or shielded bearings, the rubber seal on these components actively prevents ingress of foreign material into the bearing races, which helps maintain consistent rotational smoothness and extends the service life of the bearings themselves. The construction quality and materials used in Radient bearings ensure they can handle the repeated stress cycles inherent in RC driving, whether that's the rapid steering inputs of a buggy, the sustained rotation of a truck's drive shafts, or the precise movements required in a rock crawler. With a shipping weight of just 0.01kg per pack, these are lightweight components that have no negative impact on your RC vehicle's overall weight distribution or performance characteristics.
