Cartridge (Sealed) Bearings
Enduro Standard bearing: These bearings are made using Grade 10 Chromium Steel Balls, 52100 High Carbon Chromium Alloy Races and Riveted Steel Retainers (best to keep the balls rolling straight down the ball path even under high stress loads). These are best suited to wheels and applications where full rotations occur.
Enduro MAX bearing: Also known as full-complement bearings, these cartridge bearings do not use retainers like the Standard bearings, and can therefore have more ball bearings than the Standard. These bearings have a higher load rating and are suited to applications such are suspension pivots. MAX bearings are made using Grade 10 Chromium Steel Balls, 52100 High Carbon Chromium Alloy Races.
