Bicycle Headset Bearings

Bicycle Headset Bearings

The headset is the set of components on a bicycle that provides a rotatable interface between the bicycle fork and the head tube of the bicycle frame itself. The short tube through which the steerer of the fork passes is called the head tube. A typical headset consists of two cups that are pressed into the top and bottom of the head tube. Inside the two cups are bearings which provide a low friction contact between the bearing cup and the steerer. There are four main types of bicycle headsets: threaded type, threadless type, integrated type and internal type.

Bicycle Headset Bearings Types
The bicycle headset bearings are used in headset to reduce friction. The main types of bicycle headset bearings usually are
1. Sealed ball bearings, also called cartridge bearing. The full ball bearing includes inner ring, outer ring, nylon cage, balls, grease and double-sealed or single-sealed cap.
2. Caged ball bearing includes loose balls and steel cage.
3. Loosed ball bearing

Plane Slide: The plane slides are usually designed to have mechanical movement parts which perform the action of moving the slide with a variety of movement technologies. The most common options are those of roller tables, dovetail slides and XY tables which are operated via a drive machine part.

Sealed Ball Bearing
There three integrated standards of sealed ball bearings.

Campagnolo Standard:
45/45. These standard bearings are commonly used in road bikes. Head tubes with this standard have a 42.0mm inner diameter.
Cane Creek Standard:
36/45. These standard bearings are very common on mountain bike frames and a fair amount of road frames. Head tubes with this standard have a 41.1mm inner diameter,bike bearings.
FSA Standard:
36/36. This standard is not commonly used for fully integrated headsets.

ISUTAMI mainly supplies sealed ball bearings that the inner and outer rings have special angles with 45/45, 36/45, 36/36. All these bearings look similar. Our bicycle headset bearings can be used in FSA, CANE CREEK, CHRIS, KING, HOPE, VP, TH, FIRST, NECO, ZERONINE brand headsets.
