About this part

This is set of two replacement 5x10x4mm bearings for the XRAY T2 1/10th scale touring car. These bearings are used to support the drive axles. Top-quality professional ball bearings for a super-free, super-smooth drive train. These highest quality ball bearings are fitted with special rubber covers, and are degreased and lightly oiled with Aero Shell Fluid 12 oil for maximum smoothness, long life, highest tolerance and maximum performance. These ball bearings have more (and larger) balls inside the cage than the regular ball bearings, making them much more resilient under loads. The side covers are easy to remove for quick and comfortable servicing.

Very poor quality. Worst than my used kyosho bearings. Too much play against balls and rings. Very dissapointed for a product from Xray.

Great bearings! 5 XRAY Buggies raced regularly for a year! Not a single bearing failure!

I have to agree with the comment written before mine. The bearings for this car are weak. I would advise you to update your bearings because after a few runs of hard driving, the bearing start to weaken. This would be my only complaint about this car. Besides that, the rest of the car is strong.
