DALON self-lubricating sintered bronze bushing 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.

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 BUSHING ADVANTAGE:
With no moving parts, sintered 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.
DALON BUSHING APPLICATIONS:
DALON Sintered bronze bushing are recommended for following movements:
- Rotation
- Oscillation
- Linear
Other different type of materials is available for specific requirements, such as:- Higher speeds requirement
- Higher loads requirement
Industrial:- General assembly machinery, industrial vehicles, automation, farm machinery, sewing machines,
- bottling machines, key duplicating machines, electrical switchgears, mobility, toys, etc.
Household appliances:- Washing machines, fans, woodworking machines, vacuum cleaners, extractor fans.
- coffee machines, juicers, rotisseries, hand tools, air conditioning, boilers, etc.
Home appliances:- Lawnmowers, roller shutters, office swivel chairs, locks, garage doors, awnings, sliding windows,
- hinges, furniture, gardening, etc.
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 75mmDALON BUSHING FAQ:Q: Bushing type selection?A: The metallic structure of the self-lubricating bushing can be made from a wide range of bronze or iron based alloys. To select the proper material for a given application, it is necessary to check the maximum values of the material characteristics in comparison with:- Shaft linear speed - v
- Applied load - p
- pv (load x speed) factor
Shaft hardness and surface roughness and other parameters such as workingtemperature and type of lubrication, etc.Q: Lubricant Oil Selection?A: Standard impregnating oil conforms to SAE 30 specificationsLubricants are suitable for the temperature range from -40°C to 150°CAlso have option for customer to made special oil impregnation by selfQ: De-impregnation & Re-Impregnation?A: De-impregnation required Degrease and wash in appropriate solventEliminate the lubricant in a furnace heated around 400°C for 40 minutes under a neutral atmosphere such as N2, or with reducing agent such as N2 + H2Re-Impregnation need Immerge during one hour the parts in an oil bath heated at a temperature between 60°C and 120°C, depending on oil viscosity .Then cool down in an oil bath back to room temperature. Finally drain and dry the self-lubricating bearings.Q: Factory or Trading Company?A: DALON established in 2002 and have two factories under DALON group with shareholders, one workshop specialized in sintered bronze bushing and another handles all sintered filter and silencers.Q: What is MOQ?A: We are enjoying to grow up together with all of our clients whatever big or small orders. You will become bigger and bigger to be with DALON.Q: Can DALON make customized products?A: Yes, DALON can offer OEM / ODM manufacturingQ: Will drawing or sample design safe after DALON get it?A: DALON will NOT release your design to any third parties without your permission. Usually we will sign NDA before all drawing and samples.Q: Can DALON offer design services?A: DALON have R&D and can offer special design about your requirements with drawing 3D in format IGES/STEP,PDF/ CAD in DGW/DXF & photos.Q: How about Quality System?A: DALON have ISO9002 quality system and in-house inspection by Projector, CMM, Hardness Tester, Roughness Tester, Salt Spray Tester, Tensile Strength Test, Caliper, Micrometer, Height Gauge, Ring and Plug Gauge, Pin Gauge ,etc.Q: About Sample?A: DALON can supply the samples for FREE, but the customers have to support the tooling cost if have and the courier costQ: Tooling Charge?A: Tooling charge is one off when first order, all future orders would not charge again even tooling repair or under maintaince.Q: Lead Time?A: DALON usually effect delivery within 21days after advance payment. Stock items could be delivered within 3days. If item need open tooling, consider extra 7days.Q: Payment Terms?A: Advance 50% and balance against copy of shipping B/L. For long term business DALON have more advantage terms for payment.Q: How to deal with the complains if happens?A: In any case of complains, please contact DALON within 30days after receive the goods, DALON will find the root causes and corrective & preventive actions. DALON will take full responsibility for the claims.
