Mounted on the shaft of the Needle roller bearings have bilateral and unilateral closed open. Drawn cup closed proximal end surface can withstand the axial guiding force. Needle roller bearings are generally not attached to the inner ring. In the journal of the occasion can not be hardened and ground, you can use the inner listed in the table. Needle roller bearings in hardened steel outer ring and needle roller cage assemblies can not be separated. Free space to store lubricants can extend relubrication intervals. Needle roller bearings with cylindrical rollers of roller bearings, relative to its diameter, roller both thin and long. This is called needle roller. Despite having a smaller cross-section NKX needle roller bearings, still has a high load capacity needle roller bearings, needle roller bearings fitted with thin and long roller (roller diameter D≤5mm, L / D≥2.5 Needle bearing, L is the length of the roller) needle bearing type, therefore radial structure is compact, its diameter size and load capacity with other types of bearings, minimum diameter, especially for radial mounting dimensions restricted needle bearing structure bearings, governance and needle, needle roller bearings provided by the governance needle. Linqing municipal and needle roller bearings plant (www.zhgzzc.com) class in physical ring needle roller bearings, bearing roller type needle roller bearings, curve roller type needle roller bearings, and other industries have high visibility, integrity management, quality both services, please contact us or consult our "Commercial Union Service" it!
