This miniature bearing features a 1/8-inch bore, a 1/2-inch outer diameter, and a 0.172-inch width, with double shields and a maximum operating temperature of 302°F. It is identified by manufacturer part number SR2AZZA3MC3SRL.

Frequently Asked Questions

What is the EZO R2A miniature ball bearing used for?

The EZO R2A is a high-precision radial ball bearing used in miniature mechanisms such as dental handpieces, small motors, and instrumentation. Its double-shield design and 302°F max temperature suit high-speed, low-torque applications where contamination resistance is needed.

What are the specifications of the EZO R2A bearing?

The EZO R2A is an inch-system bearing with a 1/8-inch bore, 1/2-inch outer diameter, and 0.172-inch width. It has double shields, a maximum operating temperature of 302°F, and is identified by bearing industry number R2A and MPN SR2AZZA3MC3SRL.

Where to buy the EZO R2A bearing worldwide?

3G Electric supplies the EZO R2A bearing worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time; we source and deliver this precision component to any country.

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

Select the EZO R2A by matching bore, OD, and width to your housing and shaft dimensions. Consider load, speed, and temperature: this bearing handles up to 302°F. Double shields suit dusty environments. For high-speed use, verify lubrication and clearance requirements with the manufacturer.
