KOYO RNA5911 anti-corrosion, large radial load, the main size 63x80x34 mm Needle Roller Bearings in stock!

The flow line of the KOYO RNA5911 bearing lubricant is at the edge of the inner ring of the Needle Roller Bearings. It is difficult to obtain the lubricating oil at the contact point with the large end face of the roller, and the lubricating part of this part needs more lubricating oil. Therefore, the KOYO RNA5911 bearing rib is on the outer ring, so that the KOYO RNA5911 bearing can lubricate the outer ring edge and the roller surface contact part, and at the same time can store lubricating oil even when it is at rest, avoiding the burn accident of the KOYO RNA5911 Needle Roller Bearings when starting. In order to avoid the oil discharge channel, the power loss and temperature rise of the oil agitation will be too high. The KOYO RNA5911 bearing inner diameter and outer diameter thickness is 63x80x34 mm, which is twice the performance of the ordinary structure. Since the inner ring has no ribs, the KOYO RNA5911 has a reduced temperature, which reduces the possibility of creep between the inner ring and the shaft. The KOYO RNA5911 bearing adopts the outer ring guiding mode so that the cage can guide the roller to run smoothly without skewing, avoiding vibration and excessive wear, which is also beneficial to the high speed operation of the KOYO RNA5911 bearing.
