Motorcycle Ball Bearing

  1. Motorcycle ball bearing are used in various applications on motorcycles, including wheel hubs, engines, transmissions, and suspension systems. These bearings are designed to support radial and axial loads, and to operate at high speeds with minimal friction and wear.
  2. They are typically made from high-quality materials such as chrome steel or stainless steel, and come in a range of sizes and configurations to fit different motorcycle models and applications. Proper maintenance, including regular lubrication and inspection, can help to extend the lifespan of motorcycle ball bearing and ensure reliable and safe operation of the motorcycle.
  1. Bearings are widely used in various machinery. It can be said that as long as you running a machine, bearings are inseparable. Bearings are key components of motorcycles. For all kinds of bearings, its role is very different.
  2. Motorcycle Ball Bearing are generally used in the internal drive train and wheels of the engine, flat ball bearings are used on the front fork, and needle bearings are used on the crankshaft connecting rod and part of the drive gear shaft. Generally speaking, the front wheel of a car under 100cc is 6200.6201.6300.6301. The rear wheel is 6301.125cc. The front wheel of a 150cc car is 6301. The rear wheel is 6202.6302.
Motorcycle Ball Bearing

6200.6201.6202.6203.6204.6205.6206.6300.6301.6302.6000.6001.6002.6003.6004.62/22.62/28.62/32.63/22.63/28.63/32. It is also more commonly used.

  1. First of all, the durability of various bearings is different. Among them, ball bearings are the most durable. Therefore, motorcycle engine crankshaft bearings, main and countershaft bearings, and front and rear wheel bearings mostly use ball bearings. This kind of bearing has strong impact resistance and is convenient for gear oil.
  2. Ball bearings are the most durable at both ends of the main and auxiliary shafts of motorcycles. For example, the Tianjin Honda 90 engine has a very low failure rate, and there are very few major repairs due to bearing damage.
  3. The main reason is its reasonable design and scientific bearing selection. Therefore, ball bearings are so popular with major machinery manufacturers that they are irreplaceable.
Needle roller bearings have other advantages.
  1. They are small and compact, and can be rotated with small space components, such as crankshaft small-end needle roller bearings (such as two-stroke motorcycles), C100 countershaft small-end needle roller bearings, and GY6 machine rear wheel output Needle roller bearings for shafts and two-stroke scooter overrunning clutches are matched with needle roller bearings.
  2. Bearings in these parts cannot be replaced by other bearings because of the extremely limited space for matching parts. Especially the ultra-thin shim-shaped needle roller bearing on the AX100 transmission gear shaft shows the unique function of the needle bearing, which not only plays the role of shim clearance adjustment, but also solves the relative sliding between the gear and the gear.
  3. But the durability of needle roller bearings is not good, especially the big and small needle rollers on the crankshaft of two-stroke motorcycles. If the lubrication is poor, it is easy to lock up. When the copper sleeve replaces the bearing, the durability is worse. The copper sleeve at the right end of the camshaft on the FXD125 cylinder head is easily damaged and difficult to repair when the lubrication is poor. Only the cylinder head can be replaced, which increases the maintenance cost.
  4. Secondly, the sound-absorbing effect of the bearing at the joint of each part has its own merits, especially when the copper sleeve is used instead of the bearing, the combination is soft and the noise is small, so the copper sleeve is still widely used by many motorcycles, such as C100 countershaft small head, DX crankshaft small head For some multi-cylinder engine crankshaft small heads, copper sleeves are used instead of bearings, and the effect is very good.

The impact resistance of Motorcycle Ball Bearing

Precision Ball Bearings
  1. Bearings used in motorcycles must have strong impact resistance in certain key parts, such as two sets of pressure bearings on the steering column of each motorcycle, and ball bearings are the most resistant to impact.
  2. When motorcycles are running on bumpy roads, pressure bearings are the most vulnerable to damage, while ball bearings have the best effect, followed by needle bearings. In the motorcycle transmission system, ball bearings are the most durable, followed by needle bearings, and copper sleeves are the least durable.
  3. Some motorcycle repairers replace the small-end crankshaft needle with a copper sleeve, mainly because the copper sleeve has a good noise reduction effect. In addition, the needle roller bearings on the main and auxiliary shafts are replaced with copper sleeves. I think it is not advisable, because the transmission mechanism is to transmit torque and output power.

The disassembly and assembly of Motorcycle Ball Bearing

  1. Disassembly and assembly of the bearing on the wheel hub of the vehicle. It is inevitable that the car’s moving bearings will malfunction. If the wheel hub bearing is slightly loose, it can be knocked down and replaced, which is easier.
  2. If the ball bearing cage is broken to cause the bearing to “fall apart”, it will be much more difficult to remove the inner and outer circles of the bearing. It is necessary to use electric welding to weld a smaller Fes bearing on the outer circle of the bearing
