Bones Reds 7 mm bearings are the best economy priced bearings you can buy. Reds were developed to be an affordable alternative to Bones Swiss and feature ground and superfinished chromium steel balls and races, a high speed Nylon ball retainer, Speed Cream lubricant and a non-contact red rubber shield. This combination of quality components and careful quality control makes them faster, smoother and longer lasting than any other bearing in their price range.
* Single, non-contact, removable rubber shield for easy cleaning and less friction.
* High speed Nylon® ball retainer for greater strength and speed.
* Pre-lubricated with Speed Cream™ racing lubricant.
* Skate Rated™ clearances, tolerances, materials and lubricant provide the best performance and durability possible.
This bearing fits 7mm trucks only. Only certain models of roller skates use this size bearing - standard today is 8mm
