Sparkfun Deep Groove Ball Bearings - 2Z/ZZ (6-Pack)

Smooth operation and friction reduction are effortlessly achieved with these thin Deep Groove Ball Bearings. Crafted for light-load and high-speed conditions, they are constructed from high-precision GCr15 bearing steel, ensuring exceptional wear resistance. Each bearing in this six-pack boasts a compact size with an 18mm outer diameter, 12mm inner diameter, and 4mm thickness, making them ideal for numerous small-scale applications.

These bearings are designed for simplicity and safety, featuring a self-contained design that integrates seamlessly into existing systems. They require significantly less maintenance compared to unshielded alternatives, making them a convenient choice for various projects.

Both sides of the bearings are equipped with robust rubber seals, providing dual shielding. This feature acts as a formidable barrier against contaminants such as dust, dirt, and other dry particles, ensuring reliable performance even in challenging environments.

With efficient lubricant retention, these bearings keep essential internal grease securely enclosed, which significantly extends their service life. This makes them a reliable option for applications that demand smooth and quiet operation, as featured in the AgXRP Starter Kit.
