ABEC 5 bearings from Enduro Bearings feature R64 hardened 5th degree chrome steel balls, making them suitable for high precision applications. They move in vacuum-formed treads made of 52100 carbon chrome steel, which are particularly resistant and durable. The nylon graphite ball bearing cages have virtually no friction, and ensure constant double-sided supply of Rheolube 374A grease.
