Discover the Ultimate Guide to Ball Bearing Sizes: A Comprehensive Reference Chart

In the realm of industrial machinery and automotive engineering, ball bearings play a crucial role in ensuring smooth and efficient operation. Selecting the correct ball bearing size is paramount to maximizing performance and longevity. This comprehensive ball bearing sizes chart will empower you with the knowledge to make informed decisions for your specific application.

Story 1: Benefits of Using a Ball Bearing Sizes Chart

Benefit 1: Enhanced Equipment Performance

According to the American Bearing Manufacturers Association (ABMA), using the correct ball bearing size can improve equipment efficiency by reducing friction and wear. It ensures that the bearing operates within its optimal load capacity, minimizing downtime and prolonging service life.

Bearing Size	Load Capacity (kN)
6000 Series	8.7 to 116
6200 Series	14.3 to 186
6300 Series	21.1 to 276

Benefit 2: Cost Savings

By selecting the appropriate ball bearing size, you can avoid premature failures and costly replacements. Oversized bearings increase friction, while undersized bearings risk overload and damage. Using the ball bearing sizes chart ensures that you invest in the right size for your specific needs.

Bearing Size	Estimated Cost (USD)
6004	$2 to $5
6205	$5 to $10
6306	$10 to $15
