James Williams Verified Owner Friday, Oct 14 2016 (about 8 years ago) ProTek RC 5x8x2.5mm Metal Shielded “Speed” Bearing (4) I bought these to replace the bell crank bearings in my Yokomo YZ-2. The stock Yokomo bearings only lasted about a month. I’ve had these installed for about 6 months. They are still working great. View all reviews
