lower  roller bearing

1. The exquisitely made lower roller bearing is a precision rolling needle bearing to bear pure radial loads.Its inside and outside rings and rolling needles are carefully selected for saaembling.The components of the inside and outside rings'holding frame are interchangeable,allowing to effectively keep the identity of the radial end play during the entirely interchange of the bearings.
2. The holding frame is made of high performance imported material,able to work sustainedly and steadily for a long time under the temperature condition at -40~120.
3. The positioning plate surface is chrome-plated to strengthen its anti-rusting ability and avoid the waste down twining out of rusting,therefor,effectively stopping the waste down entrance into the rolling lane.
4. The grinding liquid is applied in the exquistite processing of the inside ring diameter hole,outside ring diameter hole and surface,bringing a good roundness,minimized coarseness,bringing the inside and outside rings' precision upward by two grades,compared with the conventional lower roller.
5. A large-volume reducion of vibration and noise,reduced wearing-out,more easier value calibration of the roller,reduction of the mechanical waves during running,noticeable improved yarn body CV value,service life extended by more than 3 years than the conventional lower roller.
6. In case of pure cotton fine yarn carding,the yarn threads will more embody their advantages;the yarn body level will bi fairly heightened. Their application on the 100000-spindle spinning frames in Ningbo Bailong Special Textiles Co.,ltd.has gained a good report.
