Drawn Cup Needle roller bearings with a thin metal forming the outer ring needle roller bearings. Its main feature is the low sectional height and the ability to withstand high loads. Mainly used for compact, inexpensive and needle roller bearings inside the hole can not be used as cage assembly raceway bearing configuration. Bearings and bearing housings shall install an interference fit. If it can save me axial positioning shoulder, retaining ring and other functions, then the bearings inside the hole can be done very simple and economical. Mounted on the shaft of the drawn cup needle roller bearings with bilateral and unilateral closed open. Drawn cup closed proximal end surface can withstand small axial guiding force. Needle roller bearings are generally not attached to the inner ring. In the journal can not be hardened and ground applications, you can use the table listed in the inner ring. Needle roller bearings and hardened steel outer ring needle roller cage assembly can not be separated. Lubricant storage free space can be extended relubrication intervals.

Lithium grease NAV4008 Needle Roller Bearings These bearings equipped with polyurethane or synthetic rubber friction seal, which is filled with good rust resistance, suitable for operating temperatures from -20 to + 100 ℃. A seal bearing inner ring is wider than the outer 1mm, this is the bearing in the machine axis relative to the displacement of the bearing box with a little work but also to ensure a good seal and to prevent injury to the bearing contamination. There lubricated bearing inner hole, you can configure it as needed bearings, lubricated by the outer or inner supplement. 4074105 needle roller bearings Needle roller bearings _ _ Needle by LINQing municipal governance and needle roller bearings plant.
