Radial Ball Bearings | GMN Bearing USA

Radial Ball Bearings (a.k.a, “deep groove” ball bearings) are the most popular type of high-precision bearing. They are versatile and fit into applications when:

You have limited space & a pair of Angular Contact Bearings won’t fit
Your application has low to moderate speeds (RPMs)
When axial loads move in both directions

Our Radial Ball Bearing Products

Manufactured to ISO 15 (DIN 625) Standards. GMN radials are also manufactured to ABEC 7, ABEC 9 standards with a designated precision class of 4 (P4) and 2 (P2).

What parts make up a radial ball bearing?

Most bearings consist of inner and outer rings with raceways, rolling elements (i.e. balls), a cage (to hold the rolling elements) and sealing elements. If necessary, depending on the application, they may be furnished with parts, such as snap rings, O-rings, etc.

This handy illustration labels all the different parts that make up a radial ball bearing.

Checklist for Choosing The Right Bearing

First, find out the operating conditions for the application, then take a look at the below general guideline to help you select the right bearing for your application.

Application Description & Bearing Selection

First, think about the application and specify the operating requirements (RPM, loads, duty cycles, etc.), operating environment (temp, contaminants, etc.). The bearings will need to support all these specific needs.

Here are all the things to think about:

Application (electric motor, conveyer, machine spindle, etc.)
Required RPM, Duty cycle, and expected life
Load (magnitude, direction and type), vibration(s)
Working/Ambient temperatures
Potential assembly/disassembly condition issues
Lubrication type and methods

Making a Decision

Even after you have defined the required bearing attributes, you could be offered slight variations on the specs, based on availability. So take a necessary step to define the most important attributes for your bearing needs. Here are some options to consider:

Rank the most important bearing attributes to support the decision/choice of bearing
Cost
Delivery time/ stock location
