10-Pack R188-ZZ Bearings - 1/4" X 1/2" X 3/16", Double Metal Shield, Chrome Steel

Need a small, reliable bearing for a project or repair?

This 10-pack of R188-ZZ bearings is a great value.

Each one measures 1/4 inch inner diameter, 1/2 inch outer diameter, and is 3/16 inches thick - a super common size for all sorts of small mechanisms, hobby projects, tools, and light industrial applications.

They're deep groove ball bearings made from high-quality chrome steel (not the cheaper carbon steel) for better durability and performance.

The 'ZZ' means they have metal shields on both sides to keep grease in and dirt out - they come pre-lubricated so you can use them right out of the pack.

Great for reducing friction and handling both radial and some axial loads.

Think electric motors, RC cars, fans, conveyor rollers, skateboards, or even fixing a household appliance.

Having a 10-pack is brilliant because you can experiment, have spares, or use them in multiple projects.

Donepart focuses on these small precision parts, so you're getting a solid component for your money.
