Oil Sleeve Bearing – Sintered Iron Flanged Bushing 25×35×45×5×25

DALON’s 25×35×45×5×25 oil-impregnated flanged iron bushing is a compact, self-lubricating sleeve bearing designed for applications that demand consistent lubrication and high structural strength. Manufactured from sintered iron and vacuum-impregnated with oil, this bushing offers long-term wear resistance with zero maintenance, making it ideal for both rotational and oscillating motion in various mechanical assemblies.

The flanged design allows for easy installation and axial retention, particularly useful for housings that experience vibration or shifting loads. With dimensions formatted as ID × OD × Flange OD × Flange THK × Total Length, this bushing is well-suited for OEM component integration and replacement parts in heavy-duty industrial settings.

FAQ – Frequently Asked Questions

Q1: What is the main benefit of an oil sleeve bearing?
It provides automatic lubrication from within, reducing friction and wear over time without the need for manual greasing.

Q2: What is the function of the flange?
The flange acts as a stopper or locator to prevent axial movement and simplify installation into housings.

Q3: Can I use this bushing in vertical installations?
Yes. The flange design helps maintain stable alignment in both horizontal and vertical setups.

Q4: How is the bushing lubricated without external grease?
During operation, heat and motion release oil from internal pores, keeping the shaft lubricated.

Q5: Is this product available in metric and inch sizes?
Yes. DALON offers both metric and imperial sizing options for global compatibility.

Q6: What is the delivery time for custom versions?

  • Standard tool: ~30 days

  • Custom-developed tooling: 35–40 days including mold preparation

Q7: What are common alternative terms users search for?

  • Self-lubricating iron bearing

  • Oil sintered flange bushing

  • Flanged iron sleeve bearing

  • Oil embedded sintered bearing

Q8: What industries typically use this bearing?
Used in industrial machinery, agricultural implements, motor assemblies, pumps, power tools, and OEM replacement units.
