Angular Contact Ball Bearing Series

Many angular contact bearing manufacturers have three or more dimensional series to accommodate higher speeds or higher loads than “standard.” In particular, the most common series names are:

• ISO 18 Series - highest speed, lowest load bearings
• ISO 19 Series - second highest speed, with the second lowest load bearings
• ISO 10 Series - highest load, second lowest speed bearings
• ISO 02 Series - highest load, lowest speed bearings

ISO Equivalents To Waltz Series Designations

Many times, manufacturers have further separated the ISO dimensional classes by adding a higher speed variant with the same dimensions. The following table summarizes Waltz product offerings:

ISO Series	Waltz Designation
ISO 18	718 Series Angular Contact Bearings
ISO 19	719 Series Angular Contact Bearings
ISO 19 (high speed)	H719 Series Angular Contact Bearings
ISO 10	70 Series Angular Contact Bearings
ISO 10 (high speed)	H70 Series Angular Contact Bearings
ISO 10 (high load)	B70 Series Angular Contact Bearings
ISO 02	72 Series Angular Contact Bearings
