I just bought a needle bearing for using it for px gear selector bearing.
But the bearingI bought (IKO BA188Z) is a little bit different type of bearing.
The needle is less half than the bearing I usually have used.

I found that the bearing I bought has a lower load rating. and high RPM.
But the shape is the same as the bearing SIP is now selling.

The attached files are the information on the bearing.


Can I use this bearing for PX gear selector bearing?
Or throw it away?
Thanks!

The outer axle/output shaft ball bearing takes the load of the rear of the scooter and the force driving it. It is essentially in line with the center of the wheel. The inner one, basically, just locates the end of the shaft and has relatively little force on it. The axle also turns at a relatively low RPM. I think you'd be fine with it.

Looks like it should be ok. If I'm working it out right your highest rotational speed for the rear axle at 130km/h would be about 2800 or a little over half the top speed of the bearing.

The original bearings had a lot of needles, whereas the new ones are like the one you bought. So far I have not had any problems with the new type.

Thanks! is the load rating of 130km/h only 2800n? It's much lower than 8000n..! Thanks!

No, I'm saying that the allowable rotational speed from your chart is 5500rpm, and that at 130kmh the rotational speed of the axle is roughly 2800rpm - as far as I can work out.
