SLIDING SLEEVE BUSHING 20X23X10

DALON’s Sliding Sleeve Bushing 20×23×10 is a compact, high-performance bronze sleeve bearing designed for oilless, dry-running, or marginally lubricated applications. Engineered with precision using powder metallurgy, this sintered bronze bushing features a uniform porosity structure pre-impregnated with lubricant, providing reliable self-lubrication during operation without the need for additional grease or oil.

The sleeve format (inner diameter 20 mm, outer diameter 23 mm, and length 10 mm) makes it ideal for tight-space installations where consistent shaft support and minimal friction are essential. Its small size is particularly suitable for use in electric motors, linear actuators, automation linkages, and small mechanical systems where traditional lubricated bearings would be impractical.

Made of a high-quality bronze alloy, this bushing resists wear, reduces operational noise, and ensures smooth motion across a wide range of environments—from dry indoor machinery to light industrial tools. It also offers excellent dimensional stability, vibration dampening, and corrosion resistance.

FAQ – Frequently Asked Questions

Q1: What is the benefit of a self-lubricating bronze sleeve bearing?

It eliminates the need for grease or oil during use, reducing maintenance and increasing reliability in enclosed or hard-to-reach installations.

Q2: Can this bronze sleeve be used in vertical shafts?

Yes. It can handle radial loads and is suitable for both horizontal and vertical shaft installations when load conditions are appropriate.

Q3: Is the 20×23×10 size customizable?

Yes. DALON offers full customization including ID, OD, and length, depending on the application. Contact us for engineering support.

Q4: How does this sleeve bearing compare with plastic bushings?

Bronze bearings provide higher load capacity, superior thermal stability, and greater resistance to wear under continuous rotation compared to plastic types.

Q5: What is the typical delivery time?

Standard parts are usually shipped within 30 days. Custom-designed products with new tooling take 35–40 days including mold development.

Q6: What’s the minimum order quantity for customized bushings?

It depends on the design and application. Please contact DALON directly to evaluate your custom needs and order feasibility.

What Do People Also Ask – Answered

Q: Are bronze sleeve bearings good for high-speed applications?

They are suitable for moderate speeds. For high-speed precision systems, always evaluate PV (Pressure × Velocity) limits or consult DALON for optimal fit.

Q: Can bronze bushings be reused or re-lubricated?

They can be reused if undamaged. They’re oil-impregnated but can be re-oiled in some cases, depending on the sintered structure and application.

Q: Are sleeve bearings better than ball bearings?

For low-speed, high-load, or dirty environments, sleeve bearings are often superior due to simplicity, noise reduction, and maintenance-free performance.
