product details

These Ezo bearings, imported from Japan, are renowned for their strength, precision, and exceptionally low resistance.

Just installing these bearings alone can increase rate of fire due to a significant reduction in friction.

These bearings have a .68mm flange thickness, which leaves plenty of room for shimming in most gearboxes.

Aeroshell 12 (AF2) oil is solely added for storage and corrosion resistance; the bearings will require lubrication prior to use.

If epoxying these bearings into a gearbox shell, exercise caution to prevent any adhesive from seeping into the bearings, races, or bore.

The selector plate may require modification to not interfere with the bearings.

Contains: 6x J-caged Open Japanese Bearings
Dimensions: 3x8x3mm
Flange thickness: .68mm

Ezo bearing

Great bearings super smooth and quiet

These are actually so stupid strong its incredible.

Generally, you want to use a bushing underneath the spur gear as that's where a significant amount of stress is, however when I initially built my DSG I did not follow this advice and used these in my whole gearbox, however this has caused me NO issues.

Whats insane about these gears, is that in my SP150 Brushless 14:1 Siegetek DSG, I was getting gnarly PME, given that PME puts extreme stress on the bevel gear, generally the first thing that fails is the bearings in the shell, i've had this happen multitudes of times on SSG's with crappy bearings.

Somehow, the SIEGETEK SPUR GEAR pin that goes into the bearing holes, snapped off instead. I have no idea how the bearings were stronger than the siegetek spur, (and im a bit sad about losing a $50 gear over an $8 bearing) you can be confident these are a good buy.

I've put 60,000+ rounds through these bearings and they show no signs of visible wear.

That being said, like with any bearings, make sure to pack them with grease before you use them, or they will fail in under 5000 rounds.

These are the J-caged bearings you've heard about, and yes, they are as ridiculous as you've heard and seen. Your average bearings are good enough, but these I can only describe as near frictionless by comparison. Your average gear spinning free on an average bearing will spin for around 5-7 seconds. On these bearings they will spin for upwards of 30 and smoothly and slowly come to a stop in contrast to other bearings where they will stop smoothly but quickly. An entire gear train shimmed right will spin easily and for a long time with these bearings, and my first build with these runs smooth to a degree I have never experienced before. Your experience may vary, but these are absolutely worth it. Make sure to pair them with a good quality gearbox so you know all components are getting the most from these.
