Inch Size Miniature Flanged Ball Bearings FR2zz

Inch Size Miniature Flanged Ball Bearings FR2zz

The FR2zz is a miniature flanged ball bearing with a 0.125″ bore and 0.375″ outer diameter, made from durable chrome steel. It handles radial loads up to 121 lbf and spins smoothly at speeds up to 56,000 RPM.

Its shielded design keeps dirt out while the stainless steel cage ensures long-lasting performance. The flange provides extra stability, making it easier to mount in tight spaces.

This bearing works well in temperatures from -86°F to 230°F and requires lubrication for optimal performance. Ideal for small devices like drones or precision instruments where space is limited.

Weighing just 1.53g, it’s lightweight yet robust for its size. Compliant with RoHS and REACH standards for safe use.

Application

Where Is FR2zz Bearing Used?
FR2zz Bearing is commonly used in small electric motors and precision instruments due to its compact size and shielded design, which keeps dust out while maintaining smooth rotation. The inch sizing makes it ideal for American-made equipment where metric bearings aren’t suitable.

In automation systems, FR2zz Bearing fits neatly into robotic arms and 3D printers, where its low friction and high-speed capability ensure accurate movements. The stainless steel cage adds durability, even in continuous operation.

For consumer electronics like cooling fans or small appliances, FR2zz Bearing’s lightweight construction and reliable performance make it a go-to choice. Its temperature range also handles everyday use without issues.

The flanged design of FR2zz Bearing helps secure it in place during assembly, reducing misalignment in tight spaces. This feature is particularly handy in DIY tools or hobbyist projects where stability matters.
