Merdith Roach Friday, Aug 9 2013 (about 12 years ago) ProTek RC 5x10x4mm Metal Shielded “Speed” Bearing (10) I agree these are the best $1.00 clutch bearings I’ve tried by far. The metal shield stays in place unlike most rubber sealed bearings and stay smooth and free over time. I can take these out and clean them with some denatured alcohol and blow them out and re-oil them and keep on using them. I was tired of constantly loosing shields with other brands and throwing them away. 2 customers found this review helpful.
