NK Bearings NK17/20 Needle Roller Bearing 17x25x20mm

  Needle roller bearings are roller bearings with cylindrical rollers, and the rollers are both thin and long relative to their diameter. This type of roller is called a needle roller. Despite having a 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, making it particularly suitable for support structures with limited radial installation dimensions.
  According to different usage scenarios, bearings without inner rings or needle rollers and cage components can be selected. At this time, the journal surface and outer shell hole surface that match the bearing are directly used as the inner and outer rolling surfaces of the bearing. To ensure the same load capacity and operating performance as bearings with ring rings, the hardness, processing accuracy, and surface quality of the shaft or outer shell hole raceway surface should be similar to those of the bearing ring raceway. This type of bearing can only withstand radial loads.
