At FUSHI we manufacture and use Angular Contact Bearings (ACB) for our headsets. We use only the best manufacturing and quality control methods available. The manufacturing process begins with the rough shape of the bearing races being machined from high quality steel. Both the inside and outside of each race is then precision stone-ground to reach its final shape. Computer controlled grinding equipment is used to grind each race to exact tolerances. The races are then assembled with the balls to create the finished bearing.

Caged Bike ball bearing Description :

Enable to replace original parts (crankshaft bearing, headsets, hubs). The diameter are measured inside and outside (it’s an approximate value in mm). Item : CBB52H8 Type : Angular Contact Bearing Inside Diameter : 40 mm Outside Diameter : 52 mm Thickness : 8 mm Inner Chamfer : 45 degree Outer Chamfer : 45 degree Qty: 1 Lot = 2 Pcs

The color of the seal is not sure. If you mind it, please contact us before you buy the bearing.

All about Headset Bearings:

1. How many different types of bearings are used in the modern day headset Answer: There are at least 6 different kinds of bearings used in the bicycle headset. They include; radial bearings, thrust bearings and angular contact bearings. These three types of bearings all use ball bearings. The second category of bearings is the roller bearings which include the standard roller bearing and the tapered roller bearing. Both of these use cylindrical rollers. 2. There are many different types of bearings. Which one is best for the bicycle headset and why Answer: Angular contact bearings are the most appropriate bearing for most headset applications. The primary reason is due to the fact that it is very efficient at dealing with the angular force that is exerted upon it. Whereas most deep groove industrial bearings are very efficient at dealing with vertical or horizontal loads, the pressing angle associated with the bicycle headset is much more angular. Most of headset use big diameter axle to increase the strength. As the limited space, the bearing should have a big bore with thin wall of inner ring and outer ring to insert in. ACB has a primary advantage that reinforces axial loads over than deep groove ball bearings. Angular Contact Ball Bearing is very efficient at dealing with both vertical (radial) and horizontal (axial) loads. Its great performances differ from other industrial bearing that only perform well in one direction. In many applications, ACB is used in pair due to its internal construction. It should be installed face to face or back to back in order to support the forces coming from any directions. 3. Are there different types of Angular Contact Bearings Answer: Yes. In fact, we makes four different types or grades of angular contact bearings. They are: -High End ACB- We manufacturevery high-end angular contact bearings that feature stainless races and ball bearings, or Ceramic balls. While these bearings have a minimal chamfered area, because they press in to the headset cup, they offer superior longevity, durability and performance. -Sealed ACB- Featuring highly polishes races, angled chamfer areasand high grade balls, FUSHI brand contact bearings come in a variety of sizes and grades, These bearings slip fit into headset cups or head tubes. -Economical ACB- These sealed bearings have the same general features as above, but with precision ground ball races instead of the highly polished ball races. Designed for OEM applications, these bearings are reliable and durable. -Serviceable cup and cone ACB- we both offer a serviceable ACB that can be disassembled, serviced and re-assembled. Utilizing a caged ball bearing race, these bearings are economical, serviceable and durable. 4. Are the various bearings interchangeable Answer: Sorry. The various styles/colors of bearings are not interchangeable. Damage can result to your frame or headset if the wrong replacement bearing is installed. 5. What if my bearings are old and dirty and I can not tell what size the bearing is Answer: FUSHI offers a headset bearing gauge that will help to identify the type/size of the bearing and/or the sizing of your integrated style headtube. 6. My bicycles are sold in areas that have very adverse and wet weather. Does fushi offer a bearing that is more rust and weather resistant Answer: Yes. we also offer stainless steel version with stainless inner and outer races as well as stainless ball bearings. 7. What are micro spacers and how are they used Answer: Micro spacers are 0.25mm thick and fit between the compression ring and the top cover. Integrated head tubes are specially machined to accept proprietary bearings. Due to frame manufacturing tolerances, the vertical height of the bearing pocket can very resulting in an imperfect fit between the top of the head tube and the headset top cover. Any number of Micro spacers can be used in order to achieve the correct clearance.
