This document gives requirements and guidance to obtain the optimum bond between backing and bearing metal for thick-walled multilayer plain bearings. This optimum bond depends on the chemical composition, the state of stress, the structural arrangement and the machining of the bond surface of the backings. NOTE Control of the manufacturing process is an important requirement to achieve an optimum bond between backing material and bearing metal.
Abstract
Overview
ISO 6280:2018 - Plain bearings: Requirements and guidance on backings for thick-walled multilayer bearings - specifies requirements and practical guidance to achieve an optimum bond between the backing and the bearing metal in thick-walled, multilayer plain bearings. The quality of the bond depends on backing material chemistry, stress state, structural arrangement and the machining of the bond surface. The standard emphasizes process control during manufacture to ensure reliable bonding and bearing performance.
Key topics and technical requirements
- Backing materials: Acceptable backings include steel and cast steel, cast iron (lamellar or spheroidal graphite) and cast copper alloys. Examples of copper alloys: CuSn10, CuPb5Sn5Zn5.
- Steel / cast steel:
- Backings should be heat-treated for normalizing and stress relieving before lining.
- Typical element contents for bonding: **C
