This double-shielded bearing features a 3/16 in bore, 5/16 in OD, and 0.125 in width, with a maximum operating temperature of 302°F. The manufacturer part number is SRW156ZZA3MC3SRL.

Frequently Asked Questions

What is the EZO R156 miniature ball bearing used for?

The EZO R156 is a high-precision extended inner ring radial ball bearing used in miniature mechanisms such as dental handpieces, small motors, and instrumentation. Its double-shielded design and 302°F max temperature suit high-speed, low-torque applications where space is limited.

What are the specifications of the EZO R156 bearing?

The EZO R156 is an inch-system miniature bearing with a 3/16 in bore, 5/16 in OD, and 0.125 in width. It is double-shielded, has a maximum operating temperature of 302°F, and carries the bearing industry number R156. The manufacturer part number is SRW156ZZA3MC3SRL.

Where to buy the EZO R156 bearing worldwide?

3G Electric supplies the EZO R156 bearing worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this high-precision bearing to any country.

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

To select the correct EZO miniature bearing, match the bore, OD, and width to your shaft and housing dimensions. Consider load, speed, and temperature—the R156 handles up to 302°F. For shielded or sealed options, verify the closure type. Consult EZO's catalog or a bearing specialist for fit and tolerance.
