Product Description

The EZO R166 is a high-precision extended inner ring radial ball bearing, part of the inch-system R166 series. It features a 3/16 in bore, 3/8 in OD, 0.125 in width, double shields, and a maximum operating temperature of 302°F (MPN SRW166ZZA3MC3SRL).

Frequently Asked Questions

What is the EZO R166 miniature ball bearing used for?

The EZO R166 is a high-precision extended inner ring radial ball bearing used in applications requiring compact, inch-system bearings, such as small motors, instrumentation, and light-duty conveyors. Its double shields protect against contamination, and it operates up to 302°F.

What are the specifications of the EZO R166 bearing?

The EZO R166 bearing has a 3/16 in bore, 3/8 in OD, 0.125 in width, double shields, and a maximum temperature of 302°F. It is an inch-system bearing with industry number R166 and MPN SRW166ZZA3MC3SRL.

Where to buy the EZO R166 bearing worldwide?

You can source the EZO R166 bearing through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide locations. Contact us for availability and lead time.

How to select the correct EZO miniature ball bearing?

To select the correct EZO miniature ball bearing, match the bore, OD, and width to your housing and shaft dimensions. For the R166, ensure a 3/16 in bore and 3/8 in OD. Consider load, speed, and temperature limits; double shields suit dusty environments.
