Frequently Asked Questions

What is the NTN RA3 radial ball bearing used for?

The NTN RA3 radial ball bearing is designed for high-temperature applications where reliable rotation under heat is required. Its double-shielded construction protects against contaminants, making it suitable for industrial machinery, conveyors, and HVAC equipment that operate in elevated thermal environments.

What are the specifications of the NTN RA3ZZ/2AS bearing?

The NTN RA3ZZ/2AS is an inch-system radial ball bearing with a 3/16-inch bore, 1/2-inch outer diameter, and 0.196-inch width. It features double shields, an alloy steel ring, and the bearing industry number RA3. This high-temperature model is built for durability in demanding industrial settings.

Where to buy NTN RA3 bearings worldwide?

You can source NTN RA3 bearings worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we supply genuine NTN components for high-temperature applications.

How to select the correct NTN radial ball bearing for high-temperature use?

To select the correct NTN high-temperature radial ball bearing, verify the system of measurement (inch vs. metric), bore size, outer diameter, and width. For the RA3 model, ensure the bearing industry number matches RA3 and the part number RA3ZZ/2AS. Confirm operating temperature range with NTN specifications for your application.
