Large Intermittent Axial Load Needle Roller Bearing 2637474 for High Speeds

Product Description

Needle roller bearings are roller bearings with cylindrical rollers, which are thin and long relative to their diameter. This type of roller is called a needle roller. Despite its small cross-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 roller length), so the radial structure is compact. When its inner diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest, which is particularly suitable for support structures with limited radial installation dimensions.

Depending on the application, a bearing without an inner ring or a needle roller and cage assembly can be selected. At this time, the journal surface and the housing hole surface that match the bearing are directly used as the inner and outer rolling surfaces of the bearing. In order to ensure that the load capacity and operating performance are the same as those of a bearing with a ring, the hardness, machining accuracy and surface quality of the shaft or housing hole raceway surface should be similar to those of the bearing ring raceway. This type of bearing can only bear radial loads.
