Deep groove ball bearings in inches

The inch deep groove ball bearing is a single-row ball bearing whose bore, outside diameter, and width are expressed in inches instead of millimeters. It supports moderate radial and axial loads in both directions and operates at high speeds. It is mainly used in North American-made equipment, agricultural machinery, pumps, fans, and transmissions where the shaft and housing are in inch dimensions.

Designations are more varied than in the metric system because each series is identified by its own prefix. In SKF, series such as EE and EEB appear in inches, and D/W for miniature bearings of the same measurement. In the examples, EE 2 TN9 and EE 3 TN9 carry the suffix TN9, which indicates a polyamide cage; EEB 3-2Z and D/W R3-2Z/P6 carry 2Z, two metal shields. The suffix P6 indicates a tighter precision class than normal. With the MRC prefix, such as MRC.R10FF and MRC.R10ZZ, bearings of those same dimensions are listed.

To choose one, you need to know the shaft diameter, the housing diameter, and the width, and then the closure: open, with shields, or with contact seal. The seal offers more protection against dirt and moisture, and the shields cause less friction when speed is high. Internal clearance also matters, which is defined according to the fit and operating temperature, so it is advisable to copy all the suffixes from the original code.
