Needle Roller and Cage Assembly (AFBMA 18.2.3.2) NIA · 模型 219262
An NIA type component is a single-row radial rolling element consisting entirely of a cage (the retaining framework) and a full set of slender, cylindrical rollers called needle rollers. No Bearing Rings: This component does not come with integrated inner or outer metal races. Instead, the rollers track directly on the hardened and ground surfaces of the machine's shaft and the housing bore where it is installed High Load Capacity in Small Spaces: Because the needle rollers have a large contact surface area (line contact) relative to their size, they provide an exceptionally high radial load-carrying capacity Compact / Low Profile: Because it lacks rings, it offers the lowest possible cross-sectional height for any rolling-element bearing arrangement, making it ideal for compact spaces.
