Brass Sleeve Bearing

This double-step knurled brass insert bushing is precision CNC lathe machined from solid brass rod. The outer dual-ring step structure locks firmly inside plastic after injection molding or hot melt pressing, effectively preventing rotation and pull-out during repeated screw assembly.

Tuoyuan Metal brass features excellent wear resistance, thermal conductivity and rust-proof performance compared with aluminum inserts, ideal for electronic products requiring frequent disassembly and heavy load connection. All dimensions, inner bore diameter and outer knurl width can be fully customized to match customer plastic mold cavities.

Why Tuoyuan Metal’s Brass Bushings Perform Better

We only source premium brass. These materials boast great thermal conductivity and innate anti-corrosion performance.

Our precise CNC turning machining supports ultra-tight tolerances as narrow as±0.005mm, ensuring seamless press fitting every time.

These brass sleeve bearings work perfectly for low-speed, heavy-load equipment applications, scenarios where ordinary bearings wear fast or malfunction easily.

A straightforward, budget-friendly alternative to complex ball bearings that reduces your overall machine footprint.

Where These Brass Sleeve Bearings Work Best

1. Automotive and Transportation

Chassis and Steering: Smoothly channels movement in steering linkages, suspension setups, and critical engine parts.

Small Motors: Reduces wear and tear inside wiper motors, alternator pivots, and heavy-duty vehicle joints.

2. Heavy Machinery and Industrial Equipment

Power Transmission: Built to withstand constant friction in industrial gearboxes, transmission shafts, and hydraulic pumps.

Precision Alignment: Ideal for complex automated assembly setups, where each durable brass sleeve bearing requires flawless alignment with a CNC machined threaded spacer.

3. Electronics and Telecommunications

Thermal and Motion Control: Keeps precision micro-motors, cooling assemblies, and heat dissipation setups running quietly.

Non-Magnetic Pivots: Perfect for internal structural pivots where steel parts would interfere with magnetic signals.

4. Construction and Building Hardware

Architectural Fittings: Enhances the lifespan of heavy commercial door hinges, robust facade fittings, and high-end decorative hardware. If you are designing luxury or heavy-duty fixtures, incorporating a reliable brass sleeve bearing ensures smooth, lifetime operation.

FAQ

Q1: Is brass a suitable material for bearing use?

A1: Definitely a solid pick. Brass sleeve bearings come with built-in self-lubricating traits, are easy to machine, and resist rust. They also avoid jamming even under damp conditions or with only occasional lubrication.

Q2: Are custom oil grooves and sizes available?

A2: Sure, we support full OEM and ODM manufacturing at Tuoyuan Metal. We regularly tailor inner and outer diameters, overall lengths, flanges, plus custom oil groove designs per client requests. We can also pair your bearings with matching CNC threaded spacers and other fittings in one package, so you don’t need to source separate parts elsewhere.

Q3: What surface finishing services can you finish within our own factory?

A3: Our environmentally compliant production shop provides a full range of in-house treatments: zinc-nickel electroplating, vacuum heat treatment, German Wagner electrostatic powder coating, and high-gloss fine polishing.

Q4: What’s your minimum order quantity and production lead time?

A4: We own the complete supply chain from raw material to finished goods, so our production lead times stand out fast among competitors. Our MOQ is flexible, fully adjusted according to your technical drawings or physical samples.
