Foreword

This standard and ISO 4379:1993 "bearing copper alloy bearing," the non-equivalent.

The standard proposed by China Machinery Industry Federation.

This standard sliding bearing by the National Standardization Technical Committee (SAC/TC236) centralized.

This standard was drafted. Zhejiang SF Oilless Bearing Co., Ltd., Zhejiang Bearing Co., Ltd., Zhejiang Changsheng Sliding Bearings Co., the company.

This standard by the National Standardization Technical Committee Secretariat slide bearing responsible for the interpretation.

This standard is the first release.

Introduction

Copper alloy inlaid solid lubricating bearings are cast copper alloy substrate and the substrate out orderly, appropriate size hole, then insert the solid lubricant, this structure is a combination of copper alloys and their respective characteristics of solid lubricating materials may be difficult to form a lubricating oil film and by Article Limitations on not add lubricant occasions.

Condominiums and straight with a wall-type structure type with reference to the kinds of bearings GB/T 18324-2001, also derived from the thrust washer and slide Two structural types.

Bearing copper alloy inlaid solid lubricating bearings

1 Scope

This standard specifies the copper alloy inlaid solid lubricating bearing structure type, basic dimensions, technical requirements and test methods.

This standard applies to the solid lubricant embedded in line with GB/T 1176 as specified in the copper alloy matrix, processed from mosaic Solid lubricating bearings (hereinafter referred to as bearing).
