DALON BUSHING INTRODUCTION:
DALON self-lubricating SAE 841 Bronze Bushing are manufactured of pressed copper and tin powders by sintered technology and impregnated with lubricating oil and high porosity.
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 SAE 841 Bronze Bushing to work under hydrodynamic conditions. which resulting in a very low friction coefficient and maintenance-free for general engineering applications.

Startup friction causes this porous SAE 841 Bronze Bushing to release a thin layer of oil on the bearing’s surface.
DALON BUSHING MATERIAL STRUCTURE
SAE841 ASTM B438-70; SintA50
Sintered Bronze and iron based self-lubricating bushings are made of two different functions:
The metallic alloy structure which supports and transfers the mechanical loads
The oil lubricant or graphite contents which separates two surfaces in relative motion and to reduce friction.
DALON SAE841 BRONZE BUSHING ADVANTAGE:
With no moving parts, SAE 841 Bronze 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.
An extremely wide range of operating loads, speeds and temperatures:
●Dynamic loads from 6 to 75 MPa
●Linear speeds up to 8 m/s
●Operating temperatures from - 180°C to + 300°C
Reduce of design and ownership costs
●Lower cost compared to cast metal and machined bearings
●Complex designs and forms possible
●High dimensional accuracy
●Excellent surface finish
●Reduced weight compared to similar non-porous components
●General assembly machinery, industrial vehicles, automation, farm machinery, sewing machines,
●bottling machines, key duplicating machines, electrical switchgears, mobility, toys, etc.
●Lawnmowers, roller shutters, office swivel chairs, locks, garage doors, awnings, sliding windows,
●hinges, furniture, gardening, etc.
DALON SAE841 BRONZE BUSHING AVAILABLE DESIGNS:
●Cylindrical plain bushings
Custom made to order Sintered bushings, please specify ID and OD and Length. The difference between the ID and OD must be at least 2mm, Length Maximum 75mm
