Graphite Bearings And Bushings
Here at EastCarbon, we produce high-performance graphite bearings in a wide range of shapes, sizes, and compositions. Our graphite bearings are perfect for areas that need lubrication but are hard to reach, especially unsanitary, or host a particularly hostile environment.
Also referred to as plain bearings or bushings, these cylindrical bearings are a simple solution for low-load applications.
Our flagged bearings manage axial thrust force and have a rim (or flange) on one end.
Our graphite thrust bearings support axial loads in conjunction with rotating shafts.
Control linear movement with self-lubricating, abrasion-resistant wear plate bearings.
Graphite Bearings
Thanks to their impressive mechanical and physical properties, our graphite bearings can meet the requirements of the most demanding applications. They are non-galling, self-lubricating, and extremely durable—even when exposed to corrosive elements or harsh conditions.
Standard, self-aligning, and heavy-duty options with linear expansion allowance.
Graphite needle or roller bearings follow a track, transforming reciprocating to linear motion.
EastCarbon graphite radial bearings are designed specifically to support radial loads.
These bearings are engineered to deal with force in the direction of the shaft.
Made from a special silicone carbide-graphite composite material for enhanced properties.
We impregnate these graphite bearings with metals like nickel, cast iron, or antimony.
High-carbon compact crystalline graphite with an up to 99% purity composition.
We recommended this material for submerged bearings due to its increased impermeability.
Graphite Bearing Applications
Our graphite bearings provide a convenient install-and-forget solution for sites that are difficult to lubricate, where traditional options would fail. For example, graphite bearings offer an excellent solution in machinery where oscillating movements make it tricky to form a stable film of oil. Their versatility makes them ideal for various industrial applications, including but not limited to:
- Agricultural Machinery
- Pulp and Paper
- Nuclear Energy
- Mining
- Automotive
- Manufacturing

The Ultimate Cost-Effective Bearings
Graphite bearings by EastCarbon offer an economical alternative to other bearing and lubricating products, like metal, oil, or grease. Their powerful mechanical makeup and self-lubricating properties mean they require no maintenance. Plus, they endure a long operating lifespan, which saves you costs on replacement parts and downtime.
Unique Benefits of Graphite Bearings
Also called oilless bearings, our graphite bearings can run dry or submerged. They’re resistant to dust and dirt and are a hygienic option for cases where using a lubricant like oil or grease would contaminate the product (for example in food production). Because they’re resistant to thermal shock, you can use them in high-temperature industrial equipment.
Why Choose Us?
When you choose EastCarbon for your graphite bearing needs, you know you’re dealing with a professional and reliable team. We strive to deliver outstanding service every time and pride ourselves on the consistently high quality of our bearings.
“I just want to say what a game-changer it’s been using EastCarbon’s graphite bearings. Before, we were replacing something like 20 bearings every single week in our industrial ovens. Since we switched to the bearings from EastCarbon, I haven’t needed to replace any. It’s been over a month and they’re still going strong.”
While we focus on manufacturing the highest quality graphite bearings, we also make sure that our solutions are cost-effective.
Using advanced CAD software, we can create custom bearings to suit your unique needs. We can also reverse-engineer the design from a sample you send us.
As leaders of the field, we’re committed to continuous innovation and use the latest machinery and techniques to produce your bearings.
We’ve optimized our process for maximum efficiency, so the time from ordering to delivery is as quick as possible.
Frequent Asked Questions
A cause of unusually rapid wear of graphite bearings is often misalignment during installation. This leads to uneven friction and will speed up degradation. If your bushings or bearings are exposed to excessive load or temperatures outside the recommended limits, this may also reduce their lifespan.
Thanks to our customization capabilities, we have an endless variety of bearings and bushings for sale. They include graphite ball bearings, thrust bushings, self-lubricating washers, high-temperature bushings, carbon bushes, graphite-plugged bronze bushings, carbon thrust bearing solutions, graphite air bearings, graphite-impregnated bronze bar, graphite-impregnated bronze plat, and more.
Extruded graphite is used for applications with less intense demands, like water pumps and board dryer bearings.
Graphite isn’t typically used for some types of bearings, like journal bearings. When it comes to how journal bearings work, other materials have more fitting properties.
Graphite grease can be useful for some bearings but isn’t always ideal for wheel bearings. This is because it doesn’t have the kind of heavy-duty lubricating properties needed for high-speed, heavy-load applications. Having said that, it can be effective for things like graphite skateboard bearings. Its dry lubricating qualities help reduce friction without attracting as much dirt and debris as traditional oils would do.
The cost depends on your specific bearing or bushing design and material selection as well as your physical shipping location and order quantity. For instance, bulk orders will bring the individual per-item cost down.
It usually involves press-fitting the bearing into the housing. You need to take care that the alignment is precisely correct to avoid cracking. In some cases, you might need to use temperature adjustments to secure the fit.
