Product Description

The EZO R155 is a corrosion-resistant high-clearance miniature ball bearing with a 5/32 in bore, 5/16 in OD, and 0.359 in flange diameter. This open-style bearing, identified by industry number R155 and MPN SFR155A3MC3AF2, is designed for applications requiring resistance to corrosion and increased internal clearance.

Frequently Asked Questions

What is the EZO R155 miniature ball bearing used for?

The EZO R155 is a corrosion-resistant high-clearance miniature ball bearing used in precision instruments, medical devices, and light industrial equipment where resistance to moisture or mild chemicals is needed. Its open design and increased internal clearance accommodate thermal expansion or misalignment in compact assemblies.

What are the specifications of the EZO R155 bearing?

The EZO R155 bearing has a 5/32 in bore, 5/16 in OD, and 0.359 in flange diameter. It is an open-type, corrosion-resistant high-clearance miniature ball bearing with industry number R155 and MPN SFR155A3MC3AF2. The flange aids axial location in confined spaces.

Where to buy the EZO R155 bearing worldwide?

3G Electric supplies the EZO R155 bearing worldwide. As a global industrial sourcing partner, we handle full logistics and customs clearance to deliver this corrosion-resistant miniature ball bearing to your facility. Contact us for availability and lead time for your region.

How to select the correct EZO R155 bearing for an application?

To select the EZO R155, verify that your shaft diameter matches the 5/32 in bore and housing fits the 5/16 in OD. The open design suits applications without contamination risk. The high-clearance (C3) internal fit is ideal for applications with temperature variations or press-fit housings.
