GB/T 3882-2017Rolling bearings -- Insert bearings and eccentric looking collars -- Boundary dimensions (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 3882-1995 "Rolling bearing outer spherical ball bearings and eccentric sleeve dimensions", and GB/T 3882-

Compared with.1995, the main technical changes are as follows.

--- Added and revised some normative references (see Chapter 2, Chapter 2 of the.1995 edition);

--- Revised the definition of the term "outer spherical bearing" (see Chapter 3, Chapter 3 of the.1995 edition);

--- Modified the font and part of the symbol (see Chapter 4, Chapter 4 of the.1995 edition);

--- Revised the description of the characteristics of the outer spherical ball bearing (see Chapter 5, Chapter 5 of the.1995 edition);

--- Added "code" chapter, "marking example" chapter (see Chapter 6, Chapter 7);

--- Increased the model and dimensions of the inch diameter outer spherical ball bearings and eccentric sleeves (see Table 1 to Table 11);

--- Expanded the size range of eccentric spherical ball bearings and modified some dimensions (see Table 1 ~ Table 3,.1995 edition)

Table 6~Table 8);

--- Revised the part of the outer diameter of the outer spherical ball bearing (see Table 4 ~ Table 6,.1995 version of Table 1 ~ Table 3);

---Modified the partial dimensions of the tapered bore and the outer spherical ball bearing with the adapter sleeve (see Table 7, Table 8, Table 4 of the.1995 edition,

table 5);

--- Expanded the size range of the inner ring eccentric table, and modified some of the external dimensions (see Table 9, Table 9 of the.1995 version);

--- Expanded the size range of the eccentric sleeve and modified the partial eccentric sleeve size (see Table 10, Table 11, Table 5 of the.1995 edition,

Table 11);

--- Revised the size of the lubrication area of the outer spherical ball bearing (see Table 1 to Table 8, Tables 1 to 8 of the.1995 edition).

This standard uses the redrafting method with reference to ISO 9628.2006 "Rolling bearing outer spherical ball bearings and eccentric sleeves.

Differences and ISO 9628.2006/Amd.1.2011 "Diameter Series 3", with ISO 9628.2006 and ISO 9628.2006/Amd.1.

The degree of consistency in.2011 is non-equivalent.

This standard was proposed by the China Machinery Industry Federation.

This standard is under the jurisdiction of the National Rolling Bearing Standardization Technical Committee (SAC/TC98).

This standard was drafted. Luoyang Bearing Research Institute Co., Ltd., Zhejiang Xinchang Peel Bearing Co., Ltd., Dongguan TR Bearing Co., Ltd.

Division, Fanke Bearing Group Co., Ltd., Fujian Fushan Bearing Co., Ltd., Fujian Yongan Bearing Co., Ltd.

5 characteristics

6 code

6.1 The code of the outer spherical ball bearing of metric inner diameter shall be in accordance with GB/T 27554.

6.2 The structure type code of the eccentric inner diameter eccentric sleeve is represented by the capital Latin letter E, its size series and inner diameter code and outer spherical ball shaft

Consistent.

6.3 Inch inner diameter ball bearings and eccentric sleeves are made of metric inner diameter ball bearings and eccentric sleeves with an inch diameter.

Code.

The bearing inch diameter code is divided by the number of millimeters of the inner diameter divided by 25.4, and multiplied by an integer of 16.

Example. UEL201-8

It indicates that the inch diameter of the bearing is 12.7 mm, that is, 12.7 ÷ 25.4 x 16 = 8, which is represented by 8.
