Product Description

Alloy With Nickle/ Bismuth Metallic Marginal-Lubricating Bearings > CSB-820/827

Alloy with Nickle/ Bismuth Metallic marginal-lubricating bearings




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.

Metallic marginal-lubricating bearings




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.


Bismuth bronze


Bismuth bronze or bismuth brass is a copper alloy which typically contains 1-3% bismuth by weight, although some alloys contain over 6% Bi. This bronze alloy is very corrosion-resistant, a property which makes it suitable for use in environments such as the ocean. Bismuth bronzes and brasses are more malleable, thermally conductive, and polish better than regular brasses. The most common industrial application of these metals are as bearings, however the material has been in use since the late nineteenth century as kitchenware and mirrors. Bismuth bronze was also found in ceremonial Inca knives at Machu Picchu.[1] Recently, pressure for the substitution of hazardous metals has increased and with it bismuth bronze is being marketed as a green alternative to leaded bronze bearings and bushings.


Bimetal-bearing is a bimetal bearing, wrapped of steel sheets with a layer of lead bronze.

The standard sizes are fitted with lubrication indents on the running surface. For standard bearings is normally the steel backing copper plated to improve the corrosion resistance. The layer of lead bronze makes it possible to use these bearings with relative long lubrication intervals.

Bimetal-bearings can be manufactured with a thicker lead bronze layer for applications where the bearing has to be machined after mounting. The material of the layer can be fitted to the special needs for the application in question.


Tech. Data


Max. Load Static 250N/mm²   Alloy Hardness ≥HB70
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 14*10-6*K-1


Usage Range


dry poor
oil lubricated good
grease lubricated good
water lubricated poor
process fluid lubricated poor


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.
