南京首恒机械设备有限公司欢迎您24小时咨询热线： 何宏翔公司电话：025-84433389811咨询Q 公司传真：025-84433389-806满装圆柱滚子轴承：满装圆柱滚子轴承特别适用于**高载荷和中等转速的场合。无密封单列和双列轴承主要用于变速箱机构，而带密封双列轴承，较适用于起重机构。单列满装圆柱滚子轴承除NJ23VH系列外，都不能分离。可分离轴承的两个套圈均可以采取紧配合，这样便于安装和拆卸。 单列满装圆柱滚子轴承的基本结构单列满装圆柱滚子轴承可以承受很大的径向载荷，也可以承受单方向轴向载荷，轴向的定位可以利用一个对称布局的同类轴承**。NCF 29V和NCF 30V系列轴承的内圈有两个固定挡边，外圈有一个挡边，它们只能承受朝向外圈固定挡边方向的轴向载荷。NJ23VH系列轴承可承受作用朝向内圈挡边方向的轴向载荷，它们的滚子被固定在外圈里，即使取走内圈也不会脱出。这样两个套圈都采取紧配合时，也易于分别安装和拆卸。 双列满装圆柱滚子轴承的基本类型双列满装圆柱滚子轴承除了可以承受很大的径向载荷和轴向载荷之外，还可以承受倾覆力矩，因此，长用作固定轴承。NNC 49V系列轴承的外圈有一个润滑油槽和若干个润滑油孔，工作过程中也可以在轴中进行润滑。NNF50B.2LS.V和NNF50C.2LS.V系列轴承两端采用接触式密封，密封圈里填有润滑脂。在使用条件较好的情况下，润滑脂可以达到轴承的工作寿命。通过外圈上的润滑油槽和润滑油孔可以进行润滑。若同样的几个轴承安装在一根轴上，则由于外圈比内圈窄，所以外圈的转速可以是不同的。这个有点适合滑轮机构，为使滑轮*固定到轴承外圈上，在轴承外圈两端均有可装弹性挡圈的环形槽。 公差满装圆柱滚子轴承的基本类型采用向心轴承的基本公差，需要轴承的其他公差请联系翊何售后服务部门。轴承游隙列轴承可允许轴与轴承座之间有一定的轴向位移在轴承内发生。因为可以作为浮动端轴承NCF...V/SL18型满装圆柱滚子轴承NCF...V/SL18型满装圆柱滚子轴承，外圈具单挡边，无挡边侧有锁圈，可对机轴作单向定位，轴承内部的轴向间隙“S”**了机轴相对于轴承箱的轴向定位移。 NJ„V/SL19型满装圆柱滚子轴承NJ„V/SL19型满装圆柱滚子轴承，用于较重负荷和低速场合，具有自锁滚子组，即使拆下内圈，滚子也不会散落，因此该型轴承安装拆卸方便，可承受单向轴向负荷，作单向定位。 满装圆柱滚子轴承的尺寸公差和几何偏差应符合GB/T307.1-94(ISO492- 1994)P0级公差等级，并且正常原始径向游隙CO，也可要求具C2到C4原始径向游隙的轴承。但定货时在轴承代号后需增加相应的后缀。橡塑螺杆挤出机一般选用C3组游隙。配合公差可参考轴承座公差的选择原则及轴公差极限选择原则。轴承允许承受一定的轴向负荷。充分的润滑是承受轴向负荷的一个先决条件。单向定位轴承和定位轴承其承受轴向负荷的挡边***受到支承。安装与拆卸，当安装或拆卸圆柱滚子轴承时**特别注意，安装或拆卸力不能直接通过圆柱滚子和套圈挡边来传递产品广泛应用：在冶金、电力、矿山、机械制造、食品、医药、汽车、纺织、化工等众多领域，首恒能在较短的时间为用户提供轴承技术 Full complement cylindrical roller bearings    SBI full complement cylindrical roller bearings are designed to carry heavy load.  Comparing with traditional bearings with cage, full complement cylindrical bearings have much higher loading capacity. The radial cross section of the type of bearings is very small. So it can be very space-saving. However the limiting speed of the bearings is relatively lower. All the multi-row cylindrical roller bearings are with a lubrication groove and one nipple on the outer ring.     A minimal load is required (C/P<25) for the bearings to run well in succession. Otherwise wear may happen when lubrication is running out or rotating speed is high. NCF…V type full complement cylindrical roller bearings are with a single rib on one side of the outer ring. A snap ring is on the other side which makes the shaft be stationary in single direction. The axial gap “s” inside the bearings ensures the axial displacement of shaft to the bearing housing case. For this “s” value, please consult SBI technical service.  NJ…V type full complement cylindrical roller bearings is applied under very high loads and slow rotating speed conditions. The rollers are self-locked and will not fall apart even if the inner ring is removed. Therefore, the mounting and dismantling of the type of bearings are convenient. The bearings can carry axial load in one direction.     NNF…2LSNVY type double-row full complement cylindrical roller bearings are with two inseparable inner rings joined by a holding ring. There is a rib in middle of the outer ring. The bearings can carry axial load in both directions and be used as stationary bearings. As the distance between the two rows of rollers is big, the bearings can also take some overturning moment. On the outer ring there are two snap grooves for axial orientation. This type of bearings is with contact seals on both sides and with lithium based grease. The operating temperature limit for the bearings is from –40 to 80℃. The kind of bearings is generally free of maintenance under some certain conditions,. But in case that there is vapor or dust, and the bearings are running in medium or high speed, supplement lubricant is absolutely necessary. If using rare oil as lubricant, the seals should be removed and all the grease within the bearings be washed out. In that case, the limit rotating speed can be increased 30%.    The dimension tolerance and geometry deviation of the type of bearings are in accordance with Grade P0 of GB 307.1-1994(ISO 492-1994). And the normal radial clearance is with group C0. Bearings with normal radial clearance of Group C2 or C4 are also available. In that case some suffix should be added to the bearing code. For example, bearings with group C3 are generally selected for the plastic extruders.     If you have requirement for higher grade bearings, please contact SBI service. For mounting tolerance, you can refer to the selection principle of housing tolerance and shaft tolerance limits. Some certain axial loads are allowed for the type of bearings. In that case, sufficient lubrication is a premise. In the single direction stationary bearings and stationary bearings, the rib that carrying axial load must be fully supported.     Attention: when mounting and dismantling the cylindrical roller bearings, the force should not be transmitted directly through the cylindrical rollers and the rib of rings.Note: The housing bore tolerance indicated in the table only applies to steel or casting bearing housing. The shaft tolerance only applies to solid shaft. In case of light metal housing, tighter mounting tolerance should be selected. Because of the influence of various factors, it is impossible to find a selecting principle that can include all the factors and the proper mounting tolerance. Therefore, the values indicated in the table are only for reference.主要销售轴承**：进口轴承**：               瑞典： SKF               日本： NSK  NTN   NACHI  IKO  THK  NMB  IJK  EZO  KOYO  FYH    ASAHI               德国： FAG  INA               美国： TWB  UBC   TIMKEA    KBS                韩国： SAMICK    SBC    国产轴承**：               瓦房店：   ZWZ               哈尔滨：   HRB               洛阳：     LYC               闽台：     HIWIN   ABBA   CPC    人本:C&U    万向钱潮:QC  上微:SW   西北:NXZ    环驰太平洋:HCH   虹山：HS   福山：FS   天马：TMB 直线系列：   直线、光轴、导轨、杆端、关节、滚珠丝杠、滑动单元、含油轴承不锈钢系列：深沟球轴承、外球面轴承、钢球、推力球轴承、调心球轴承、圆锥滚子轴承、角接触球轴承 ,陶瓷轴承，塑料轴承，玻璃球轴承  ，SL满装圆柱滚子轴承             正确的选择      **的运转  仓库图片                              导购**
