Frequently Asked Questions

What is the EZO 1212 miniature ball bearing used for?

The EZO 1212 double-shielded radial ball bearing is used in precision instruments, small motors, and light-duty industrial equipment where compact size and low friction are required. Its 1/2-inch bore and 0.156-inch width suit applications with limited axial space.

What are the specifications of the EZO 1212 bearing?

The EZO 1212 bearing has a 1/2-inch bore, 3/4-inch outer diameter, and 0.156-inch width. It is double-shielded, rated for a maximum temperature of 302°F, and uses inch-system measurement. The bearing industry number is 1212, and the manufacturer part number is SR1212ZZA3K25SRL.

Where to buy the EZO 1212 miniature ball bearing worldwide?

3G Electric supplies the EZO 1212 miniature ball bearing to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this high-precision radial bearing.

How to select the right EZO miniature ball bearing for an application?

To select the correct EZO miniature ball bearing, match the bore, outer diameter, and width to your housing and shaft dimensions. Consider load type, speed, and temperature limits — the 1212 model operates up to 302°F. Double-shielded designs retain grease and exclude contaminants.
