About the Fox Custom Bearings

Are you looking for new bearings for your airsoft gun?  Check out the Fox Custom Bearings.  They come in 3 sizes - 7mm, 8mm, and 9mm to meet the needs of most gearbox types.

The bushings/bearings are a component found inside the gearbox. They are responsible for holding the gears in position and bearing any load from the gears caused by rotation and the spring inside the gearbox. By default, some manufacturers use bushings which are simple in design and some will have bearings which feature small metal ball bearings and a multiple piece race/roller setup taking over the shape of a bushing. Every gearbox has a pair of bushings or bearings per gear, so typically a three gear configuration (sector, spur, and bevel gear) means you have six of these.

Q: What happens when a bushing or bearing fails?
A: Failure of this component in any one of your gears will cause it to turn off axis. Your electrical resistance and load will increase as a result, straining your motor and heating up your wires. If the gear is severely off its axis it could potentially cause gear damage as it tries to turn. Additionally, when a bearing fails it leaves behind small debris and the steel bearings are now floating around your gearbox that will cause damage elsewhere.

Q: When should I replace or upgrade these parts?
A: The stock components will last for some time but we recommend next time you have someone looking at your gearbox to check your bearings or bushings. They should be able to let you know when those components are looking pretty rough and when it is time to replace. By then you will want to spend a few dollars to get upgraded ones which will last indefinitely.

Bushings are pretty straight forward and are a solid piece with a hold down the center. On older guns or very cheap ones you will find these bushings to be made of plastics which wear out especially if the gun is being upgraded to shoot harder than stock. Some average quality guns will have metal bushings already but the material will still wear out because they use soft metal bushings like brass or untreated steel. Ideally you would want guns that come with hardened steel bushings already. Once we get over the inferior quality bushings, let's talk about why bushings are great. Because of the simple design there is nothing to fail except for the bushing hole to lose shape and cause your gear to turn off axis and increase load. But this would not be a catastrophic failure which could potentially happen in a bearing setup. Bushings do have a higher mechanical resistance therefore your gun does work a little harder to turn a gear riding on a bushing. But bushings will take any level of upgrades you throw at it so this outweighs the tiny little increase in rounds per second you might gain.

Bearings are an upgrade to reduce the friction of your gears turning. On an otherwise stock setup, changing to bearings will dramatically decrease your gearbox load and increase your electrical efficiency. You may see a slight gain in rounds per second too. Bearings are great for M120 and below setups generally speaking. You could go higher but their potential for failure goes up and we start to wander into the territory of theoretical builds. For high FPS setups, bushings are ALWAYS recommended. Bearings can get damaged from too much load or as a result of something torqueing a gear improperly (like piston damage).

Fox Custom is our offshoot brand of parts that we like to use in all our custom builds as well as suggested upgrades for repair work that we do locally. These are high quality precision manufactured parts designed to deliver performance and long service life. 

If you need help or consultation on repairs you could give us a ring at (888)316-7816 or shoot us an e-mail at . Although we only offer tech work to our local walk-in customers, we would still be happy to point you in the right direction. The senior staff and owners of the company have been playing for well over 15 years and certified and authorized by several major manufacturers to do OEM quality repair and warranty work.

Note: Fox does not warranty or accept returns for parts that have been installed/attempted to be installed.

Note: Due to varying manufacturer tolerances for gearbox internals, parts compatibility no matter what version might NOT fit even if it is supposedly correct and fitment is NOT guaranteed. The reality is that some parts may need fitting and some parts might look the same but the dimensions are slightly different enough to not work. This will require technical experience to identify to overcome.

Honestly, this is the only airsoft shop I will ever buy from. Their guns are always quality. Their custom work is mind blowing. Their staff is not only helpful, but always happy to help. If you are just starting out or have been playing for years, these guys have guns, gear, and good advice for every situation.

Awesome company and products. Received sooner than projected from Colorado and I'm in California. Less than 2 days from placing order to receiving it. . Everything shipped as ordered . Incredible selection and great price... Did my homework and eventually came back to them. I'm glad I did. My squad will be ordering and I be ordering more gear as well.
