Complete Guide to Ball Bearing Sizes, Types, and How to Choose the Right One
Share
When it comes to industrial equipment, choosing the right bearing is critical for performance, longevity, and cost efficiency. Whether you're replacing a worn-out part or sourcing bearings for a new project, understanding the different types and sizes can save you time and money.
What Are Ball Bearings?
Ball bearings are designed to reduce friction between moving parts and support radial and axial loads. They are commonly used in motors, conveyors, automotive systems, and industrial machinery.
At PrimeCore Industrial, we supply high-quality ball bearings built for durability and consistent performance across a wide range of applications.
Common Ball Bearing Sizes
Ball bearings come in standardized sizes, typically identified by numbers like:
6000 Series (light-duty applications)
6200 Series (general-purpose industrial use)
6300 Series (heavier loads and higher durability)
6800 & 6900 Series (thin-section bearings)
Miniature bearings (small precision applications)
Each number represents specific inner diameter, outer diameter, and width measurements.
Types of Bearings We Supply
We offer a wide range of bearing types to fit different applications:
Deep Groove Ball Bearings (most common, versatile)
Roller Bearings (for heavy loads)
Mounted Bearings (easy installation with housing)
Agricultural Bearings (designed for harsh environments)
How to Choose the Right Bearing
When selecting a bearing, consider:
Load type (radial vs axial)
Speed requirements
Environment (dust, moisture, temperature)
Seal type (Open, ZZ, 2RS)
Size and fitment
If you're unsure, our team can help you find the exact match.
