It features a double shield design, a 1/4-inch bore, a 3/4-inch outer diameter, and a 0.281-inch width, constructed with an alloy steel ring. The bearing carries the industry number R4A and manufacturer part number R4AZZA3MC3SRL.

Frequently Asked Questions

What is the EZO R4A miniature ball bearing used for?

The EZO R4A miniature ball bearing is used in precision applications requiring low friction and high-speed rotation, such as small motors, robotics, medical devices, and instrumentation. Its double-shield design protects against contamination while retaining lubrication, making it suitable for clean, light-load environments.

What are the specifications of the EZO R4A bearing?

The EZO R4A is an inch-system radial ball bearing with a 1/4-inch bore, 3/4-inch outer diameter, and 0.281-inch width. It features double shields and an alloy steel ring. The bearing industry number is R4A, and the manufacturer part number is R4AZZA3MC3SRL.

Where to buy the EZO R4A bearing worldwide?

You can source the EZO R4A bearing through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine EZO miniature bearings to procurement teams and engineers globally.

How to select the correct EZO R4A bearing for an application?

To select the correct EZO R4A bearing, verify the inch-system dimensions: 1/4-inch bore, 3/4-inch OD, and 0.281-inch width. Ensure the double-shield design suits your contamination and lubrication needs. Confirm the load and speed requirements match the alloy steel ring's capacity. Consult EZO's technical data for fit and tolerance.
