Enduro Bearings ACB 4545 150 BO - ABEC 3 - Headset bearing

Enduro Bearings ACB 4545 150 BO - ABEC 3 - 52mm x 40mm x 7mm

This bearing is designed as a headset bearing with an internal and external chamfer, see below for dimensions 

Angular contact bearings provide maximum load distribution across all of the ball bearings, unlike standard bearings which load only those at the bottom of the bearing.

This load distribution ensures bearing life is increased drastically allowing for more time spent in the saddle than the workshop.

These are black oxide (BO) bearings, which provides improved wear resistance, offering protection against bending and extends their life. This is all due to the black oxide protecting the bearing from corrosion, friction, micropittins and cracking.
