Enduro Bearings 71801 LLB - ABEC 5 - 21mm x 12mm x 5mm
Enduro's ABEC 5 is the next performance step up from the popular ABEC 3 range.
By using military level, high precision HRC-64 hardended Grade 5 Chromium Steel Balls, and 52100 High-Carbon Chromium-Alloy mirror polished races.
This combination allows Enduro's ABEC 5 bearings to use tolerances twice as tight as ABEC 3, and operate without any noise.
The Graphite/Nylon ball retainers allow virtually frictionless movement and provide constant lubrication to maximise the life of the bearing.
