Kwik Ceramic Skate Bearings 8mm (16) Accelerate faster and roll further with Kwik Ceramic skate bearings. These bearings utilise the advanced characteristics of ceramic balls and combine it with a ceramic titanium nitride coating on both sides of the bearing shield and the inner and outer bearing races to create remarkable performance. Titanium nitride is a corrosion-resistant material that hardens and strengthens the surfaces it is applied to – improving the lifetime durability of the surface by a factor of four or more and further increasing maximum roll. Sold as a pack of 16. Features: Accelerate faster and roll further than traditional steel ball bearings Ceramic ball bearings resist heat and friction, allowing for a free, fast-spinning roll Titanium nitride coated races resist corrosion and provide strength to create a high performance bearing with maximum roll Friction resistant Delrin retainers that are pre-spun with high performance oil Don't forget! One skate wheel requires 2 bearings (one on either side of the wheel core). 4 wheels require 8 bearings, 8 wheels require 16 bearings. These bearings are suitable for most current roller skates, blades and inlines. Size: 8mm Online Only Brand: Kwik
