Materials & Metallurgy

Brass Grades Offered

We manufacture our brass bushing lineup from high-quality, industry-standard alloys to ensure reliable performance. Our inventory includes the most requested US grades:

• C36000 (Free-Cutting Brass): The standard for high-machinability, excellent for precision machined brass bushing production.
• C46400 (Naval Brass): Offers high corrosion resistance, specifically used for marine environments.
• C69300 (Lead-Free Brass): Complies with US potable water regulations, perfect for eco-friendly plumbing applications.

Mechanical & Physical Properties

Our brass materials deliver the perfect balance of strength, ductility, and wear resistance.

Property	C36000 (Typical)	C46400 (Typical)
Tensile Strength	49,000 – 68,000 psi	54,000 – 75,000 psi

Material Selection Guidance

Choosing the right alloy prevents premature failure. Here is our quick selection framework:

• Choose C36000 when your project requires tight tolerances, high-speed production, and cost-efficiency for a standard brass bearing sleeve.
• Opt for C46400 if your parts face moisture, brine, or corrosive chemicals.
• Specify Lead-Free Brass for any US application involving drinking water or strict environmental compliance.

Dimensions, Standards & Tolerances

We understand that a brass bushing is only as good as its fit. If the dimensions are off by a fraction of a millimeter, your machinery rattles or your pipes leak. That is why we maintain strict, razor-sharp dimensional control across our entire inventory. Whether you need a standard brass sleeve bushing or a heavy-duty brass bearing sleeve, we deliver exact specs every single time.

Performance Characteristics of Our Brass Bushing Line

We design every brass bushing to handle tough daily wear while keeping your machinery running smoothly. Here is exactly how our components perform under pressure.

Load Capacity & Operating Conditions

Our heavy-duty brass bearing sleeve options thrive in low-speed, high-load environments. They absorb high shock loads without cracking, making them ideal for heavy equipment.

• Max Operating Temperature: Up to 300°F (149°C) for standard alloys.
• Load Type: Excellent for static and oscillating motion.

Friction & Wear Behavior

Each machined brass bushing delivers a low coefficient of friction, which prevents galling and extends the life of your mating shafts.

Feature	Performance Benefit
Surface Finish	Smooth, precision-turned surface reduces initial wear-in periods.
Lubrication Film	Holds oil or grease films efficiently to prevent metal-on-metal contact.
Wear Tolerance	Sacrificial material design protects more expensive steel shafts from damage.

Corrosion Resistance & Environment

Whether you are installing a brass pipe bushing in a plumbing system or a brass plain bearing in an industrial washdown area, moisture is not an issue. Our brass alloys naturally resist rust and hold up beautifully against water, petroleum products, and mild chemicals.

Noise & Vibration

Because brass is inherently more forgiving than steel, a brass sleeve bushing acts as a natural dampener. It absorbs operational vibrations, which cuts down on system noise and prevents premature component fatigue across your entire assembly.

Installation, Operation & Maintenance

Getting the most out of your brass bushing comes down to correct installation and regular upkeep. Even the highest-quality machined brass bushing will fail prematurely if it is forced into place or left bone-dry. We design our components for straightforward integration and long-term reliability.

Installation Guidelines

Proper installation prevents distortion and ensures the brass sleeve bushing maintains its tight design tolerances.

• Clean the Housing: Ensure the housing bore is completely free of debris, burrs, or sharp edges before insertion.
• Alignment is Key: Align the brass plain bearing perfectly square with the housing bore to prevent scoring or uneven wear.
• Use a Press Arbor: Always utilize a press arbor or pilot tool. Never strike the brass flanged bushing directly with a hammer.
• Apply Steady Pressure: Use a smooth, continuous press fit. A light lubricant on the outer diameter can ease the installation process for tight fits.

Lubrication Recommendations

While brass offers decent natural slickness, proper lubrication drastically extends the lifespan of a brass bearing sleeve.

Lubricant Type	Best Used For	Application Tip
Standard Grease	High-load, low-speed mechanical joints	Apply through grease fittings during routine maintenance.
Light Machine Oil	High-speed, low-load applications	Ideal for continuous oil-feed or drip systems.
Dry Film Lubricants	Dusty or high-temperature environments	Use graphite or PTFE coatings where wet oil attracts grit.

Maintenance & Replacement

Routine inspections keep your machinery running smoothly and prevent unexpected downtime.

• Check Clearance: Regularly measure the gap between the shaft and the brass bearing bush to detect excessive wear.
• Monitor Temperature: A sudden spike in operating temperature usually signals a lack of lubrication or shaft misalignment.
• Inspect for Scoring: Look for visible grooves or metal flakes during scheduled teardowns.
• Establish Replacement Cycles: Replace the brass pivot bushing once wear exceeds the allowable clearance limits specified for your equipment. Taking action early protects the more expensive mating shafts from damage.
