Product Description

The EZO R156 is a high-precision radial ball bearing, supplied as a double-shielded miniature bearing with a 3/16-inch bore, 5/16-inch outer diameter, and 0.125-inch width. It has a maximum operating temperature of 302°F and is identified by the manufacturer part number SR156ZZA3MC3AF2. This inch-system bearing is designed for applications requiring compact, shielded radial support.

Frequently Asked Questions

What is the EZO R156 miniature ball bearing used for?

The EZO R156 is a high-precision radial ball bearing used in compact rotating assemblies such as small motors, instrumentation, and precision machinery. Its double-shielded design protects against contaminants while maintaining low friction, making it suitable for applications with limited space and moderate speeds.

What are the specifications of the EZO R156 bearing?

The EZO R156 is an inch-system miniature ball bearing with a 3/16 in bore, 5/16 in outer diameter, and 0.125 in width. It is double-shielded (ZZ), has a maximum operating temperature of 302°F, and carries the manufacturer part number SR156ZZA3MC3AF2. The bearing industry number is R156.

Where to buy the EZO R156 bearing worldwide?

3G Electric supplies the EZO R156 miniature ball bearing worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this precision bearing to support your operations.

How to select the correct EZO R156 bearing for an application?

To select the EZO R156, verify the shaft diameter (3/16 in bore) and housing bore (5/16 in OD). Ensure the width (0.125 in) fits your assembly. The double-shielded design suits clean environments; for higher temperatures, confirm the 302°F max rating. Consult EZO's catalog for load ratings and speed limits.
