Welcome to inquire! Contact: Mr.Song. Needle roller bearing inner ring from the shaft shoulder and lock nut axially fixed realization. There are washers and lock, safe and reliable, suitable for high-speed, heavy-duty applications. End face of the needle bearing thrust washer fixed: bearing inner retaining ring from the shaft shoulder and an axial shaft fixed. Thrust bearings or ball thrust from sub-band needle or cylindrical roller cage assemblies and thrust washers. Needle and cylindrical roller thrust maintained by maintaining and lead frame. When used with a different series of DF thrust needle roller bearings bearing washers 4,074,916, can provide many different combinations of bearing configuration. As the use of high precision cylindrical rollers (needle) increases the contact length, so that the availability of high load bearing capacity and high rigidity in a small space. Another advantage is that if the part is suitable for surface adjacent raceway can be omitted when the washer 4074912 needle roller bearings, can compact design, DF thrust needle roller bearings and thrust needle roller bearings and cylindrical roller used The cylindrical surface for surface modification can reduce the edge stress and improve life.
