Bearing Set Tamiya Lunchbox/Grasshopper Ball Bearings

This bearing is a single row bearing for use with Tamiya and Lunchbox brands. This single-row bearing is built to support radial loads. This bearing has metal shields on both sides of the bearing to keep lubricant in and contaminants out and has been lubricated at the manufacturer so no additional lubrication is required. It is suitable for use with Tamiya brand Lunchbox and Grasshopper brand radio-controlled (RC) vehicles.

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
