THK INA Bearing NK42/20-TV-XL Bearings Belong to The NK Series of Needle Roller Bearings, Lightweight

INA needle bearing is a roller bearing with cylindrical rollers, which are both thin and long relative to their diameter. This type of roller is called a rolling needle. Despite having a smaller cross-section, bearings still have a higher load-bearing capacity, making them particularly suitable for situations where radial space is limited. According to situations where radial space is limited. According to different usage scenarios, bearings without inner rings or needle roller and cage components can be selected. At this time, the surface of the shaft neck and shell hole that match the bearing directly serve as the inner and outer rolling surfaces of the bearing. To ensure the same load capacity and operating performance as bearings with rings, the hardness, machining accuracy, and surface quality of the shaft or shell hole raceway surface should be similar to those of the bearing ring raceway. This type of bearing can only withstand radial loads.

• High radial load carrying capacity
• Accommodate relatively heavy axial loads due to skew or tilting
• Long service life
• Easy to mount
• Sealed for increased reliability, with relubrication feature
