Bronze Sleeve Bushings
DALON self-lubricating Bronze Sleeve Bushings are manufactured of pressed copper and tin powders by sintered technology and impregnated with lubricating oil and high porosity (20-25% in volume). The oil contained in the porosity provides a constant lubrication between bearing and shaft, the system does not need any additional external lubricant, allows this type of sintered bronze bushing to work under hydrodynamic conditions. which resulting in a very low friction coefficient and maintenance-free for general engineering applications.

Product Introduction
DALON BUSHING ADVANTAGE:
With no moving parts, Bronze Sleeve Bushings are the simplest type of bearing. Compared to ball and roller bearings, they generally handle higher temperatures and perform better in dirty environments. They are also intended by design to be self-lubricating, maintenance free and low cost.
Performance
An extremely wide range of operating loads, speeds and temperatures:
u Dynamic loads from 6 to 75 MPa
u Linear speeds up to 8 m/s
u Operating temperatures from - 180°C to + 300°C
Suitable for use in a wide range of environments
u Marine environment
u Radio-active environments
u Contact with corrosive liquids or substances incompatible with oils
u Food preparation
Reduce of design and ownership costs
u Maintenance-free operation
u Lower cost compared to cast metal and machined bearings
u Complex designs and forms possible
u High dimensional accuracy
u Excellent surface finish
u Reduced weight compared to similar non-porous components
BRONZE SLEEVE BUSHINGS standard geometries such as cylindrical, flanged and spherical bearings, DALON also developing in P/M of complex types for special purpose requirements.
As rich and long experience in P/M technology, DALON also offer Technical support for customers in the design and application of BRONZE SLEEVE BUSHINGS , selection of available materials and lubricants for Special-purpose equipment compression molds, furnaces, handling, sizing, deburring and impregnation.
