This JAZRIDER Metal Shielded RC Ball Bearing Set is tailored for routine maintenance on Tamiya M03, M04 and FF02 platforms. The kit contains 12 pieces of 5 x 11 x 4 mm and 2 pieces of 5 x 8 x 2.5 mm bearings, matching common hub and shaft locations used across these chassis types.
Metal shields protect the internal races from dust and coarse particles while allowing straightforward inspection and relubrication. This makes the set a pragmatic upgrade for hobbyists who prioritise low-maintenance reliability over specialist high-end bearings.
Set compatibility aligns with standard Tamiya bearing bores. For a tidy installation use a bearing driver or appropriate socket to avoid pressing on the inner race. Check for free rotation and absence of play before full reassembly.
