Product Description

The EZO Miniature Ball Bearing R156 is a high-precision radial ball bearing with an inch system of measurement. It features a 3/16 in bore, 5/16 in OD, and 0.109 in width, with an open design and stainless steel ring (MPN SR156 A3MC3AF2).

Frequently Asked Questions

What is the EZO R156 miniature ball bearing used for?

The EZO R156 miniature ball bearing is used in precision instruments, medical devices, robotics, and small electric motors where low friction and high accuracy are required. Its stainless steel ring resists corrosion, making it suitable for clean or mildly corrosive environments.

What are the specifications of the EZO R156 bearing?

The EZO R156 is an inch-system radial ball bearing with a 3/16 in bore, 5/16 in OD, and 0.109 in width. It has an open design, stainless steel ring, and bearing industry number R156. The manufacturer part number is SR156 A3MC3AF2.

Where to buy the EZO R156 bearing worldwide?

3G Electric supplies the EZO R156 miniature ball bearing worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time; we source and deliver this precision bearing globally.

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

To select the correct EZO R156 bearing, verify the shaft diameter matches the 3/16 in bore and the housing fits the 5/16 in OD. Confirm the 0.109 in width fits your assembly. For high-speed or low-torque applications, the open design allows relubrication. Consult EZO's load ratings for your specific load conditions.
