Racera Bobcat 7 Hybrid Ceramic Mini Skate Bearings (set of 16)

Racera Bobcat 7 Hybrid Ceramic Mini Bearings $170 + $25 for Delrin adapters

The Racera Bobcat 7 are our 11 ball mini hybrid ceramic skate bearings that are made with G5 (highest rating able to be produced) hardened high precision silicon nitride (Si3N4) balls encased in nylon cages. Silicon nitride is the hardest ceramic compound used in ceramic bearings. Our silicon nitride balls are sourced from a premium Japanese manufacturer. The material is used by NASA inside their space shuttle engines. The races are stainless steel. Fitted with steel shields as standard on the outside, which are not removable, so cleaning must be done from the inner side. Each bearing is individually tested by Racera before being offered for sale.

Racera Bobcat 7 are designed to fit 7mm axles and are $170.

Optional Delrin adapters are available to convert them to be fit into standard 22mm bearing seats and are $25 for a set of 16. If your wheels take standard bearings, you need these. If they only take Mini bearings, you don't.

Mini bearings spin up faster than standard bearings and are half the weight of standard bearing sizes, even when combined with the Delrin adapters.
