Custom Bronze Bushings Machined to Your Drawing
We machine non-standard bronze bushings from your drawing, your sketch or a worn sample part. Bores from 10 mm to 2,000 mm outside diameter, in cast, wrapped, sintered and graphite-inlaid bronze, with dimensional and material documentation supplied on request.
Send a STEP or DWG file and we will return a quotation with alloy and machining notes within one working day.

Bronze Alloys We Machine
Alloy choice is driven by load, speed, temperature and whether the joint can be relubricated. If you are unsure which grade fits, send the operating conditions and we will recommend one.
| Alloy | Type | Where it is used |
|---|---|---|
| C93200 (SAE 660) | Leaded tin bronze | General-purpose bushings under medium load with reliable lubrication. |
| C95400 | Aluminium bronze | Higher loads and shock loading in mining and earthmoving equipment. |
| C86300 | Manganese bronze | Heavy loads at low speed, such as press rams and pivot points. |
| C95500 | Nickel aluminium bronze | Combined corrosion resistance and impact strength, including marine duties. |
| C51000 phosphor bronze | Phosphor bronze | Precision bushings and spring components that need a stable bore. |
| Graphite-inlaid bronze | Solid-lubricant bronze | High temperature, washdown and inaccessible locations where oil cannot be used. |
| CuSn8 wrapped bronze | Wrapped bronze | Thin-wall bushings with lubrication pockets for compact housings. |
| Sintered bronze | Oil-impregnated | Continuous light-duty rotation without external lubrication. |
More grades, including lead-free brass and special bronze alloys, are listed on the bronze bushing materials page.
Four Manufacturing Routes
The route we propose depends on the diameter, the wall thickness and the quantity. Casting suits large diameters and one-off parts, wrapped construction suits thin walls in volume, and powder metallurgy suits small parts made in the tens of thousands.
| Route | How it is made | Typical wall | Suited to |
|---|---|---|---|
| Centrifugal and sand casting | Molten bronze is poured into a spinning or static mould, then machined to size | 5 mm and above | Large diameters, heavy sections, single parts and small batches |
| Wrapped bronze | Bronze strip is rolled and formed, with lubrication pockets or through-holes | 1 – 3 mm | Compact housings and high-volume repeat parts |
| Sintered bronze (powder metallurgy) | Bronze powder is pressed, sintered and impregnated with oil | 1 – 5 mm | Small parts running continuously under light load |
| Graphite-inlaid construction | Solid lubricant plugs are set into a cast or machined bronze body | 5 mm and above | High temperature, dry running and inaccessible locations |
Benefits of Custom Bronze Bushings for Your Industrial Needs. Graphite Bronze Bushing In Tower Cranes
Applications of Bronze Bushings in Various Industries Discover the different industries that use bronze bushings and how they are incorporated into different types of machinery.
“The graphite bronze bushing in the climbing claw mainly bears the weight of the upper part of the tower crane’s jacking sleeve, slewing middle section, upper and lower support slewing bearing, tower cap, balancing arm, counterweight, lifting arm, load trolley, cab, hoisting mechanism, slewing mechanism, luffing mechanism, and other components. We can provide unique bearing solutions with optimized features to meet the challenges of demanding applications.”

The benefits of oilless bronze bearings
Self-Lubricating Spherical Plain Bearings
A Special Spherical Plain Bearing – Does Not Require Supplemental Lubricant.
Joint bearing Also known as spherical plain bearing, its structure consists of an outer ring with a spherical surface and an inner ring with an outer spherical surface. The material can be made of stainless steel, aluminum alloy, beryllium bronze, and titanium alloy, etc. Spherical plain bearing characterized by its simple structure, small size, and high load capacity. They also have a low coefficient of friction, impact resistance, corrosion resistance, vibration reduction, a wide temperature range, and long service life. During the working process, it can be maintenance-free, and self-lubricating.
Widely used in construction machinery, heavy-duty vehicles, water conservancy facilities, machinery, etc.
