Self-lubricating bushings

One of the main characteristics of sintered parts is the presence of microporosities generated during the pressing of metal powders.
This internal structure allows the production of self-lubricating bushings, capable of ensuring smooth and long-lasting operation without the addition of external greases or lubricants.
After sintering, the bushings undergo an impregnation treatment: a process in which hot oil penetrates the pores of the material, forming an internal lubricating film that reduces friction and wear.
With over forty years of experience in powder metallurgy, DL Sintered Srl manufactures sintered bushings in bronze, steel, iron, and composite materials, co-designed with the customer to perfectly adapt to every application requirement.
Characteristics of Self-Lubricating Sintered Bushings
Durability
The self-lubricating sintered bushings guarantee long use cycles thanks to the presence of internal lubricating oil, which reduces wear and ensures consistent performance over time.
Low maintenance
The impregnation of lubricating oils within the microporosities of the material allows for autonomous and continuous operation, minimizing maintenance interventions after installation.
Noise reduction
The microporous structure of the sintered materials promotes smooth and silent movement, reducing vibrations and noise during operation.
High production repeatability
Thanks to the use of high-precision and stable molds, DL Sintered ensures excellent repeatability in the mass production of sintered bushings and gears, maintaining the consistent quality of each component.
