Features

The lead free bronze lead alloys include two different materials. CSB-820 is an alloy with Nickle content and CSB-827 is an alloy with Bismuth content. These materials have low friction coefficients and good wear resistance and they are suitable for lubricated working conditions. To improve the lubricating performance, oil grooves or oil deposits could be optional designs.

CSB-820/827

Structure:

1. Lead Free Sintered Bronze Alloy, provides good self lubricating feature and has good fatigue resistance and anti-seizure feature.

2. Steel Backing, provides the mechanical strength of the bearing.

Tech. Data

Max. Load	Static	250N/mm²	Alloy Hardness	≥HB70
Max. Load	Dynamic	140N/mm²	Operation Temperature range	-40°C~+ 250°C
Max. Speed (lubricated)		2.5m/s	Friction coefficient	0.05~0.20
Max. PV		2.8N/mm²*m/s	Thermal conductivity	60W(m*K)^-1
Tensile Strength		350N/mm²	Coefficient of thermal expansion	1410^-6K^-1

Typical Applications

These materials are suitable for using under middle load and middle to low speed conditions. The good embeddability of the alloy provides anti-dust feature of the bearings. The bearings can be used under dust environment and where containments existed. The typical applications include connection rods, undercarriage rollers, hydraulic cylinder rod eyes, material handling machinery, agriculture machinery, forest machinery and so on.
