If you're into RC cars, robotics, skateboards, bicycles, or small machinery, you know how important good bearings are. This FastEddy Bearings pack gives you 10 high-quality rubber sealed bearings with dimensions 3mm (inner diameter) x 6mm (outer diameter) x 2.5mm (width). The model is MR63-2RS, where 2RS means it has rubber seals on both sides to keep dirt out and grease in. They're made from chrome steel for durability and smooth performance. These are replacements for worn-out or stock bearings in many hobby-grade RC vehicles (check your manual for size), as well as useful in DIY projects, fidget spinners, conveyor rollers, or small tools. The rubber seals offer good protection against dust and moisture, making them more weather-resistant than open bearings. They're pre-lubricated and ready to install. Just pop out the old ones and press these in (using a proper bearing tool or careful pressure). FastEddy is a trusted name in the hobby community for reliable, affordable bearings. Note: Photos are for style reference—actual size is as listed. Keep your gear running smoothly with these dependable replacements. Order a pack and have spares on hand for your next repair or upgrade!
