Moto Premium Bearings by GRNMNSTR Roller Sports are the industry's first and only 'pre-spun' skate bearings, so they will skate just as fast on the first day as they will on the twenty-first! Automated 'pre-spinning' ensures the quality, balance, and integrity of the bearings.
Moto Premium Swiss Bearings are lightly oiled and are packaged, sealed and shipped in a reusable aluminum tube that will protect them and keep them clean and lubricated since aluminum tubes won't soak up the oil and lubrication like cardboard packaging.
Moto Bearings do not use an ABEC rating, as GRNMNSTR feels that ABEC ratings don't give their bearings justice. The Moto Deluxe and Premium Swiss both have a Glass Filled Plastic Delrin cage -- the same material the wheel hubs are made of.
Moto Bearings are available in two models: Moto Deluxe (stainless steel balls, inners and races, nylon retainers, light oil) and Moto Premium Swiss (Swiss balls, inners and races hardened with 'Ti-Nite' ceramic coating, glass reinforced nylon retainers, lightly oiled)
These Premium Swiss 8 mm bearings are sold in a package of 16.
