GJP Needle Roller and Cage Assembly Bearing KZK25.1X30.1×14 is a single row Needle Roller Bearing, and It could easibly be identified with “K”as a single type, and meanwhile “KK” is designed as double row type, at the same time KZK25.1X30.1×14 could also be name with K25.1X30.1×14, this bearing include needle rollers and steel cage only, and normally GJP call the cage type with “M” type cage, which is suitable for this bearing application, normally for this bearing, the material for cage is #20 seemless steel, and ≤0.1mm cage concentricity, and process with cage length tolerance at -0.25mm to -0.15mm, get rid of all spurs, for needle rollers, they are made of Chrome steel hardened material Gcr15, with hardness at around HRC61 to 62, on needle roller both end with double grinding process to ensure the roundness(flat end is not allowed), and needle roller front face with 4 grinding process at least, so that it could gurantee less damage on pin and connecting rod when bearing was assembled.
This Bearing could be coated with different kind of color, it could be their original color, it could be coated with silver, Copper, Black etc. which is decided by customer’s market needs and motocycle requests.
When you design this bearing, you need to be very careful on the needle roller tolerance, as instead of shaft, this bearing was insert with the pin instead, sometimes if the roller outer diameter is big, the pin could not go through the hole, and also GJP focus a lot on the both end of needle roller and the slot process, as we need to make sure the roller could move up and down in the cage slot freely and not fall down.
For the replacement market, some customer buy the cage and needle rollers separately, so that they could repair at their most conveniently.
This GJP needle roller and cage assembly bearing is popular used in the big end of connecting rod on the motor model Hero Honda.
Needle roller cage thrust assembly bearings are roller bearings with cylindrical rollers, which are thin and long relative to their diameter. Such rollers are called needle rollers. Despite having a smaller section, the bearing still has a high load bearing capacity. Needle roller bearings are equipped with thin and long rollers (roller diameter D≤5mm, L/D≥2.5, L is the length of the roller), so The radial structure is compact, and when the inner diameter and load capacity are the same as other types of bearings, the outer diameter is the smallest, especially suitable for the support structure with limited radial installation size.
Depending on the application, a bearing without an inner ring or a needle roller and cage assembly bearing can be selected. At this time, the surface of the journal and the surface of the housing hole matched with the bearing are directly used as the inner and outer rolling surfaces of the bearing. In order to ensure the load capacity and running performance As with the bearing with ring, the hardness, machining accuracy and surface quality of the raceway surface of the shaft or housing hole should be similar to the raceway of the bearing ring. This type of bearing can only bear radial loads.
