Bronze Bushings & Bearings

Our Bronze Bushings are available as C93200 Standard Stocked Sleeve Bearings, Sintered Bronze Bearings, and are also available as Custom Made to Order plain bearings. The purpose of the bearings is to protect the moving parts from wear and shock loads. These bearings have no rolling elements, unlike a roller bearing.

Sintered Bronze Bearings are unique in that they start as a powder and in most cases do not require any additional lubrication.

Standard Stocked bushings (CB Bushings) are offered in C93200 Bearing Bronze (SAE 660). We also have Standard Stocked Bushings available in SAE 841 Sintered Bronze. Between these two product lines, we feature over 1,000 different sizes available to ship from stock. These standard parts provide off-the-shelf economy for many different applications.

We also know that sometimes a Standard Bushing will not work. That is why we also offer our quote service for made to order Bushings that are "Machined to Print" or "Made from Sample" parts. We welcome drawings in a number of different formats, such as; .pdf, Word, .jpeg's or CAD file to meet our customers needs.

Depending on the type of Bushing needed, we have the ability to use many different casting methods, alloys, and sizes to meet your requirements. The most common alloys used for customer bushings are C93200, C95400, and C86300. But we have made bushings from just about every type of Bronze on the market. The alloy you choose will largely depending on the high load capacity, high speeds, axial loads, and operating temperature.

Why Bronze Bushings?

There are so many different types of bushings available - including polyurethane plastic for bushings that boast about their inability to rust. However, nothing can compare to what is offered with bronze bushings.

They are hard, strong, and are safe from rusting, too. Of course, we don't want to forget to mention their incredibly long lifespans.

Common Applications of Bronze Bushings & Bearings

You will find bearings and bushings used, one way or another, in every industry. Which means creating an actual list of uses that is not exhaustive just isn’t possible. But just to name a few places where you may find these bronze component parts:

  • Sleeve Bearing
  • Engines
  • Bicycles
  • Fishing reels
  • Hydraulic cylinders
  • Stage lighting
  • Medical and dental tools
  • Printer rollers
  • Surveillance systems
  • Kitchen appliances
  • Escalators
  • ATMs

Typically there are 3 Standard Types of Bushings

  • Sleeve Bearing
Sleeve bearings are a simple solution to ensure movement between two parts - with minimal friction and vibration. They can handle heavy loads and high temperatures with minimal impact. The result? You can rely on self-lubricating sleeve bearings under heavy use and for extended time.

  • Flange Bearing (Double Flange also)
Flange bearings are self-aligning bearings - and they are contained inside their own housing unit. One part of the housing is bolted to the unit while the other is left free. This allows the bearing to rotate within a contained area.
Flange bearings are usually used for light duty, rather than heavy duty needs.

  • Thrust Bearing (also called a Thrust Washer)
Thrust bearings are also referred to as rotary bearings. They are designed to rotate along with the moving parts of the unit they are used in. In other words, when the parts begin to rotate, it is the thrust bearing that they glide along.

Each type is available as a Plain, Grooved (Oil or Grease) and/or Graphite Plugged.

Frequently Asked Questions

What is the difference between a bushing and a bearing?

The two words - bushing and bearing - get thrown around a lot together. Sometimes they are even used interchangeably. But while they are very similar, they do have a slight difference. Let’s take a look at why this confusion is so prevalent.
A bearing is a component piece that is decided to help two different parts move without too much friction between them. There are different designs for how this works, such as ball bearings, roller bearings, needle bearings, sleeve bearings, flange bearings, etc. Depending on what you are using the bearing for, you will choose the best design.
A bushing is a type of bearing. They are also referred to as plain bearings or sleeve bearings. It moves in a sliding motion between two moving surfaces, also reducing friction.

Does brass work just as well for bushings?

Believe it or not, bronze bushings have become so popular due to their strength. Brass, on the other hand, just cannot compare. By nature, it tends to be a much softer metal that will easily deform and not hold its place.

Do bearings need to be lubricated?

Yes, you will absolutely want to make sure you are keeping your bearings lubricated. Not only does it deter corrosion, but it also reduces the wear and tear on the component.

The idea behind a bearing is to have a smooth flow with minimal friction between the two parts. Without proper lubrication, this isn’t always possible. The friction will heat up and the life of the bearing may dwindle.

Always keep your bearings properly lubricated.
