ABMA STD 7
Shaft and Housing Fits for Metric Radial Ball and Roller Bearings (Except Tapered Roller Bearings) Conforming to Basic Boundary Plan
|Publication Date:||1 January 1995|
This standard covers the general selection of shaft and housing fits for metric radial ball and roller bearings of tolerance classes ABEC 1 - RBEC 1 as influenced by the type and extent of bearing loading and other design requirements. Other tolerance classes are not covered by this standard.
Recommendations for the fitting practices of some particular types of ball and roller bearings are covered in other ANSI/ABMA standards.
ANSI/ABMA Std. No.
12.1 & 12.2 Instrument Ball Bearings
16.1 & 16.2 Airframe Ball, Roller, and Needle Roller Bearings
18.1 & 18.2 Needle Roller Bearings
19.1 & 19.2 Tapered Roller Bearings
26.2 Thin Section Ball Bearings
This standard can also be used as a guide for determining shaft and housing dimensions for inch design ball and roller bearings by using the recommended shaft and housing fits for metric bearings and applying the appropriate bore and O.D. tolerances for the inch design bearings, except those bearings covered by ANSI/ABMA Standard 15.
