DALON’s oil embedded sleeve iron bearing is a high-performance sintered iron flanged bushing, designed for medium to heavy-load rotating applications requiring excellent wear resistance and consistent self-lubrication. This specific model—SINTERED IRON FLANGE BUSHING 30×40×50×5×20—features a flange for secure mounting and axial positioning, along with oil impregnation that ensures maintenance-free operation over extended cycles.
The bearing is manufactured using powder metallurgy technology, which creates a porous structure that is vacuum-impregnated with lubricating oil during production. This design guarantees consistent internal lubrication throughout the bushing's life span, even in environments with minimal external maintenance.

Q1: What is the benefit of oil embedding in sintered iron bushings?
Oil embedding provides continuous internal lubrication, reducing friction and extending service life without external greasing.
Q2: Can this bearing be used in vertical installations?
Yes. The flanged design ensures stable axial placement, making it suitable for both horizontal and vertical mounting.
Q3: How is the flange dimension determined in your size specification?
Our sizing format follows: ID × OD × Flange OD × Flange Thickness × Total Length, ensuring accurate product selection.
Q4: Are these bearings suitable for high-load applications?
Yes. Sintered iron with graphite oil impregnation supports moderate to heavy radial loads in dynamic systems.
Q5: Can I request a different size or custom flange shape?
Absolutely. DALON offers full customization including special flange designs, tolerances, and oil types per your application's needs.
Q6: How does this product compare with bronze bushings?
While bronze offers slightly better corrosion resistance, sintered iron bushings are more cost-effective for high-load industrial applications.
Q7: What industries typically use this bushing?
Used in industrial machinery, agricultural systems, drive components, and custom OEM assemblies requiring durable and maintenance-free solutions.
