The QUBE Ceramic bearing uses ceramic ball technology. Ceramic material can take more heat than conventional steel making your bearings perform better under harsh conditions. Ceramic is also stronger than steel making your bearings less susceptible to impact shock, a common cause of bearing failure. This bearing is greased. Greased bearings take less maintenance than standard oiled bearings. Available in 7 mm or 8 mm. Packaged in a set of 16 for roller derby.
Qube is a division of Sure-Grip International.
