Description

MH-P21 Headset Bearing, 37x49x7mm, 45 Deg inner rad, 45 Deg outer 1 piece
Chrome steel races and balls, nylon cages and rubber seals. Packed with grease. Black seals.
Angular contact bearings have a wear resistance advantage over deep groove types in heavily preloaded applications like bottom brackets and headsets. This type of bearing better supports the radial and axial or thrust loads from pedaling. Since the load is better supported the bearing is more efficient and lasts longer. (Remember that they are directional when installing, I will mark the insertion direction. Top tip: only drive the outer race to prevent internal damage)
Our bearings feature beautifully ground chrome steel races which are harder and lower friction than stainless steel.
Rubber seals are pliable with just the right amount of preload to keep dirt out and resistance low.
