The precise world of bearings revolves around detailed measurements and exacting specifications.
One critical tool for ensuring optimal bearing performance is the bearing tolerance chart.
This vital reference provides insights into how bearings can fit and function within machinery, underscoring the importance of accurate measurements in bearing applications.
What is a Bearing Tolerance Chart?
A bearing tolerance chart is a detailed guideline, outlining the permissible limits of variation in a bearing's dimensions.
It serves to aid in the selection of the right bearings for specific applications, detailing key parameters such as inner and outer diameters, radial play, and axial play.
Why is it Important to Consult a Bearing Tolerance Chart?
Accurate interpretation of a bearing tolerance chart is key to achieving a proper bearing fit and function.
It helps avoid premature bearing failure, which can result from improper fit, thereby enhancing the performance and efficiency of the machinery.
How to Interpret a Bearing Tolerance Chart
Much like learning what bearing numbers mean, interpreting a bearing tolerance chart requires:
Tolerance Class: Each row usually represents a specific bearing type within a tolerance class, ranging from high to low precision, each suitable for various applications.
Dimensional Values: Tolerance charts present dimensions like ID, OD, and radial and axial play, indicating acceptable measurement ranges for bearings.
Radial Play and Axial Play: These values denote the bearing's permissible 'play' in radial and axial directions, crucial in applications with substantial load or movement along these axes.
Match to Application Requirements: The right bearing with the appropriate tolerance class can make all the difference. Table 1 below provides a comprehensive overview of the required performance, corresponding applications, and the suitable tolerance class for different scenarios.
Required performance | Applications | Tolerance class |

Bearing Tolerance Chart
Bearing tolerances, as well as the allowable values for the boundary dimensions and operational accuracy of bearings, are specified.
The rules governing these tolerances are set out in JIS B 1514-1, -2, and -3, addressing roller bearings with a focus on part 1: radial bearings, part 2: thrust bearings, and part 3: permissible chamfer dimensions. These JIS regulations are based on the corresponding ISO standards.
Bearing tolerances are categorized into six classes: 0, 6X, 6, 5, 4, and 2, with precision increasing with the class number.
Class 0 bearings suffice for regular use, while Class 5 or higher bearings are needed for intense conditions, as shown in Table 1.
These tolerances, conforming to ISO standards, may have different names globally. Table 2 outlines specific tolerances per bearing class and pertinent bearing organizations.
Standards and organizations concerned with bearings include:
JIS : Japanese Industrial Standard
BAS : The Japan Bearing Industrial Association Standard
ISO : International Organization for Standardization
ANSI : American National Standards Institute, Inc.
ABMA : American Bearing Manufactures Association
DIN : Deutsches Institut für Normung
BS : British Standards Institution
NF : Association Francaise de Normalisation
