ProTek RC 14x25.4x6mm Ceramic MX-Speed Rear Engine Bearing

This is a Protek R/C Ceramic 14x25.4x6mm "MX-Speed" Rear Engine Bearing, and is intended for use with the O.S. VZ-B V-Spec, 30VG, the original Novarossi P5, 421B, Picco P3 .28, and Axe Rossi Cobra off-road competition engines as well as any other engine that requires a 14x25.4x6mm rear bearing. ProTek MX-Speed engine bearings have 2 distinct advantages when compared to other bearings that provide decreased resistance, increased speed, load handling capabilities and extended bearing life. Precision Ball Races: A unique bearing race design is used that increases load capabilities, centering the balls in the middle of bearing race. This allows the bearing to continue to rotate smoothly when the crankshaft is subjected to harsh side and radial loads. PA46 Nylon Cage: A stronger, thicker bearing cage material has been developed that allows the bearings to withstand high nitro content fuel and excessive temperatures. The reinforced PA46 nylon has been subjected to Heat Distortion Temperat
