Introduction

Standard Evolution and Technological Innovation

GB/T 292-2023, as the fourth revised version, has achieved three major breakthroughs compared with the 2007 version:

Technical Dimensions	2007 Version	2023 Version	Upgrade Highlights
Structural Coverage	5 basic types	8 extended types	New 18 series 25° lock type, 19 series double contact angle type
Size Range	Maximum inner diameter 260mm	Maximum inner diameter 460mm	Expanded application scenarios of super-large models
Technical parameters	Single chamfer standard	Differentiated chamfers with different contact angles	Different r1smin values for α≤30° and α>30°

Core parameter analysis

Take the 71810C model as an example:

Nominal size: d=50mm, D=72mm, B=7mm
Contact angle: 15° (Type C)/25° (Type AC)
Chamfer requirements: rsmin=0.3mm, r1smin=0.15mm

Note in actual application: when axial load > radial load, 25° contact angle model should be selected first.

Typical structure comparison

Structural features	Locked inner and outer ring type	Locked outer ring type	Locked inner ring type
Applicable series	18/19/10/02/03	18/19/10/02/03	19/10/02/03
Load characteristics	Bidirectional axial load	Unidirectional axial load	Precise axial positioning
Typical Applications	Machine Tool Spindle	Gearbox	Precision Instruments

Implementation Recommendations

Selection Principles: 10/02 series are suitable for medium and low speed scenarios, 18/19 series are suitable for high speed conditions
Installation Specifications: Locking type bearings must ensure that the axial preload is within ±10% of the recommended value
Maintenance Points: Bearings with contact angles greater than 30° are recommended to shorten the lubrication cycle by 20%

Technical Extension

Compared with ISO 15:2017, this standard has stricter requirements on the width tolerance zone control of 03 series bearings (±0.5mm vs ±0.8mm)
