GB/T 28697-2012Rolling bearings -- Aligning thrust ball bearings and aligning seat washers -- Boundary dimensions (English PDF)

Foreword

This standard rule according to GB/T 1.1-2009 given draft.

This standard replaces GB/T 301-1995 "Rolling Thrust ball bearings Dimensions" in the unidirectional and bidirectional external heart Thrust Ball

Bearing portion.

This standard uses the translation method identical with ISO 20516.2007 "Rolling aligning thrust ball bearings and aligning seat washer shape

size".

Correspondence between the consistency of the standards of international documents and normative references of the following documents.

--- GB/T 274-2000 Rolling chamfer dimensions Max (ISO 582.1995, IDT)

--- GB/T 6930-2002 Rolling vocabulary (ISO 5593.1997, IDT)

--- GB/T 7811-2007 Rolling Parameter Symbol (ISO 15241.2001, IDT)

This standard also made the following editorial changes.

--- With a decimal symbol instead of ",". ",";

--- Remove the international standards outlined in the informative elements.

The standard proposed by China Machinery Industry Federation.

This standard by the National Standardization Technical Committee of Rolling (SAC/TC98) centralized.

This standard was drafted. Shengzhou Meiya Special Bearing Factory, Luoyang Bearing Research Institute Co., Ltd.

1 Scope

This standard specifies with and without aligning seat washers unidirectional and bidirectional thrust-aligning ball bearing dimensions.

Aligning thrust ball bearings < one-way bearing> aligningthrustbalbearing

Through a self-aligning bearing seat can accommodate between axis and bearing axis of the amount of skew angle thrust ball bearings.

NOTE. The spherical aligning the back seat with a self-aligning bearing seat gasket or corresponding concave spherical match.

3.2

Aligning thrust ball bearings < way bearing> aligningthrustbalbearing

By aligning seat ring and the bearing can be adapted to a certain amount of angle between the axis of the bearing axis oblique thrust ball bearings.

NOTE. spherical and the back aligning seat washer or bearing race aligning corresponding concave spherical match.

3.3

Unidirectional aligning thrust ball bearings single-directionaligningthrustbalbearing

Only to withstand a direction of axial load spherical thrust ball bearings.

3.4
