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

Provide smooth operation and reduce friction in your mechanical systems with these thin Deep Groove Ball Bearings. Designed for light-load and high-speed working conditions, this single-row bearing is made from high-precision GCr15 bearing steel to provide reliable wear resistance. Each of the six bearings has a compact size (18mm outer diameter, 12mm inner diameter, 4mm thickness) that makes them a practical choice for many small-scale applications. Simple and Safe Operation The self-contained design of these bearings makes them easy to integrate into your existing setups and requires significantly less active maintenance than unshielded alternatives. Dual Shields: Both sides of the bearing are protected by durable rubber seals. Contaminant Barrier: Provides a practical defense against dust, dirt, and other dry particles in challenging environments. Lubricant Retention: Keeps essential internal grease securely inside the bearing, extending service life. This 6-pack is the same one we feature in our AgXRP Starter Kit and is an excellent choice for applications that require smooth, quiet operation. Product includes: 6x Deep Groove Ball Bearings - 2Z
