This document is Part 2 of GB/T 19673 "Rolling Bearings - Sleeve Type Linear Ball Bearings - Accessories". GB/T 19673 has been published.

The following parts were included.

---Part 1: Dimensions, Geometric Specifications (GPS), and Tolerances for Series 1 and 3;

---Part 2.5 Series Dimensions, Product Geometry Specifications (GPS) and Tolerances this document replaces GB/T 19673.2-2013 "Rolling Bearing Sleeve Type Linear Ball Bearing Accessories Part 2: Series 5 External Dimensions" Compared with GB/T 19673.2-2013, the main technical changes in "Dimensions and Tolerances" are as follows, except for structural adjustments and editorial modifications.

a) The scope has been changed (see Chapter 1, Chapter 1 of the 2013 edition);

b) The application of GPS has been added, and some symbols and tolerance markings have been changed (see Chapters 4-9; 2013 edition).

Chapters 4 through 9);

c) Increased positional tolerances for bearing housing bores, threaded holes or mounting holes, and shaft centerlines (see Tables 2, 4, 6, and 8);

d) The value of shaft diameter tdeltads was changed (see Table 9, Table 5 in the 2013 edition).

Introduction

This document specifies the geometric elements of mechanical parts as defined in the Product Geometry Specification (GPS) system (see ISO 14638[9] matrix model).

standard.

Unless otherwise specified, the basic principles of ISO/GPS given in ISO 8015[5] apply to this document, and the principles given in ISO 14253-1[6] apply to this document.

The default principle applies to the technical specifications developed in accordance with this document.

The relationship between functional requirements and measurement methods and measurement uncertainty should be considered, and attention should be paid to measurement uncertainty.

ISO 14253-2[7].

By correctly selecting the bearing housing, shaft, shaft support block, and shaft support guide rail, the use of sleeve-type linear ball bearings can be made more convenient.

The above-mentioned bearing accessories help sleeve-type linear ball bearings achieve the required smooth, precise, and low-friction linear motion during use without...

Tremors or crawling may occur.

The correct selection of bearing housing type, shaft, and shaft support components should be determined through consultation between the manufacturer and the user.

GB/T 19673 "Rolling Bearing Sleeve Type Linear Ball Bearing Accessories" consists of two parts.

---Part 1: Dimensions, Product Geometry Specifications (GPS), and Tolerances for Series 1 and 3.This section aims to specify the dimensions, product geometry specifications (GPS), and tolerances for sleeve-type linear ball bearings.

The dimensions and tolerances of the 1st and 3rd series accessories provide guidance for product selection.

---Part 2.5 Series External Dimensions, Product Geometry Specifications (GPS), and Tolerances. This section aims to specify the dimensions, product geometry specifications (GPS), and tolerances for sleeve-type linear ball bearings.

The dimensions and tolerances of the 5 series accessories provide guidance for product selection.
