Description

HADLEY 20MM FRONT HUB (H6000110, DH H500145) HYBRID CERAMIC BEARINGS 2 PIECES
Replacing your creaky or pitted bottom bracket bearings with hybrid ceramic bearings has never been more affordable!
Increase your pedaling efficiency compared to standard steel bearings.
Our ABEC 5 bearings feature beautifully ground chrome steel races which are harder and lower friction than stainless steel.
The balls are high quality Si3N4 (silicon nitride balls) and nylon cages, filled with Shell Alvania RLQ2 grease.
Rubber seals are pliable with just the right amount of preload to keep dirt out and rolling resistance low.
Kit includes sizes:
6805-2RS
(25 X 37 X 7MM)
(2pcs)
Seals may be blue or black depending on stock.
Front DH H500145 & H600110 bearing replacement instructions.
Hadley H600110 (
24mm wrench sizes for 20mm version shown)
1)
The ends are loosened first and then removed from the hub shell – using 24mm C wrenches.
2)
The lock rings are then removed with a pin spanner tool – 33mm.
3)
Both bearings are pressed out towards the non-disc side – a socket can be used to tap out.
4)
Next the new bearing gets pressed in from the non-disc side – making sure that it completely down and perpendicular to the hub shell.
5)
Drop the spacer in
6)
Install the second bearing into the hub shell from the non-disc side.
7)
Thread and tighten disc side lock ring on first – then do the same with the non-disc side.  The non-disc side is the pre-load for the hub.  This side must not be over-tightened.  As it is tightened down, you need to check how the spacer moves between the two bearings.  It must be able to move back and forth between the bearings, but be snug – not flopping around.
8)
Put the ends back into the hub – the internally threaded end goes in on the disc side of the hub – the eternally threaded end goes into the non-disc side of the hub and threads into the other end.  These ends need to be cinched down tight.
