RNA6901 Steel Needle Roller Bearing 16x24x22mm Solid Collar Bearings Without Inner Ring 6634901 6354901/A

BearingsBearingsSolid Collar Needle Roller BearingThe solid collar needle roller bearing has compact structure, small radial size and large load carrying capacity. It is suitable for the parts of which the radial overall size is limited. It is also wide applied to the situation where the shaft or housing has the swinging motion. In general, the needle roller bearing only withstands the radial load, not the axial load. When the shaft has axial load, it can be used in combination with other bearings. However, it does not limit the axial shift of shaft or housing. The limiting rotational speed of needle roller bearing is lower. In high rotational speed of main machine, the needle roller bearing with cage shall be chosen as far as possible. In compassion with other types of needle roller bearings, under the situation of same radial size, the needle roller bearing has the large load carrying capacity and high rigidity but has high friction torque.Model RNA Needle Roller Bearings Without Inner RingThe needle roller bearing without inner ring is suitable for the parts of which the radial size is limited. Because of no inner ring, the surface of shaft journal fitted with it is acted directly as rolling surface. It is requested that the surface hardness be no less than HRC60, surface roughness, no more than 0.63μm. This kind of bearing does not limit the axial shift of shaft and housing and has high limiting rotational speed.Features:Needle bearings are roller bearings with cylindrical rollers. The advantages of needle roller bearings are small radial cross-sectional dimensions and high radial loads. Suitable for use in restricted installation spaces.Steel cage guides and evenly spaced rollers reduce friction, vibration and noise. Heat resistant and durable under heavy loads.
