影响叉车轴承寿命的关键因素对于许多的旋转机械产品来说他们的使用寿命多取决于产品中关键部位轴承部件的寿命。 “免维护”轴承不是IKO轴承永远不会损坏或失效而是指在一定的时间之内不会损坏。这里设计师们计算了轴承的使用寿命轴承的使用寿命大于或等于机械产品的大修周期这样的轴承就可以“免维护”在机械产品大修的同时更换新的轴承即可无需对使用过的轴承进行维护。
The key factor affecting the life of forklift bearings is that the life of many rotating machinery products depends on the life of the bearing components in the key parts of the products. "Maintenance-free" bearings are not IKO bearings that will never be damaged or disabled but that will not be damaged for a certain period of time. Here the designers calculated the service life of bearings bearing life is greater than or equal to the overhaul cycle of mechanical products such bearings can be "maintenance-free" in mechanical products overhaul while replacing new bearings can be used without maintenance.
脂润滑有预先在密封型轴承中充填润滑脂的密封方式，以及在外壳内部充填适量润滑脂，每隔一段时间进行补充或更换的充填供脂方式。此外，对有多处IKO轴承需要润滑的机械，还采用管道连接至各润滑处的集中供脂方式。脂润滑可做到充填一次润滑脂后长时间不需补充，而且其密封装置的结构也较简单，因此使用广泛。油润滑相对来说比较简单。经常润滑可以提高叉车轴承的使用寿命。
The grease lubrication has the sealing method of filling grease in the sealed bearing beforehand, and the filling method of filling grease in the shell interior, supplementing or replacing grease every other period of time. In addition, for machinery with multiple IKO bearings requiring lubrication, a centralized grease supply method is also adopted by connecting pipes to various lubrications. Grease lubrication can be filled with grease for a long time without supplement, and its sealing device is simple in structure, so it is widely used. Oil lubrication is relatively simple. Regular lubrication can improve the service life of forklift bearings.
进口轴承在工作中允许有轻微的运转响声，如果响声过大或有不正常的噪音或撞击声，则表明轴承有故障。
imported bearings are allowed to have a slight noise in operation, if the noise is too loud or abnormal noise or impact sound, indicating that the bearing fault.
滚动轴承产生噪音的原因比较复杂，其一是轴承内、外圈配合表面磨损。由于这种磨损，破坏了轴承与壳体、轴承与轴的配合关系，导致轴线偏离了正确的位置，在轴在高速运动时产生异响。当叉车轴承疲劳时，其表面金属剥落，也会使轴承径向间隙增大产生异响。此外，轴承润滑不足，形成干摩擦，以及轴承破碎等都会产生异常的声响。轴承磨损松旷后，保持架松动损坏，也会产生异响。
The reasons for rolling bearing noise are relatively complex. One is the wear of the bearing inner and outer rings. Because of this kind of wear and tear, it destroys the matching relation between bearing and shell, bearing and shaft, leads to the axis deviating from the correct position, and produces abnormal sound when the shaft moves at high speed. When the forklift bearing is fatigue, its surface metal peeling will also increase the radial clearance of the bearing to produce abnormal noise. In addition, bearing lubrication is insufficient, dry friction is formed, and bearing breakage will produce abnormal noises. After the bearing is loose and loose, the cage will loose and damage, and it will also produce abnormal sound.
在机构运转时，安装IKO轴承的部位允许有一定的温度，当用手抚摸机构外壳时，应以不感觉烫手为正常，反之则表明轴承温度过高。
During the operation of the mechanism, the part where the IKO bearing is installed allows a certain temperature. When touching the shell of the mechanism by hand, it should be normal not to feel hot, otherwise it indicates that the bearing temperature is too high.
轴承温度过高的原因有：润滑油质量不符合要求或变质，润滑油粘度过高；机构装配过紧(间隙不足)；叉车轴承装配过紧；轴承座圈在轴上或壳内转动；负荷过大；轴承保持架或滚动体碎裂等。
The causes of excessive bearing temperature are: the quality of lubricating oil does not meet the requirements or deterioration, the viscosity of lubricating oil is too high; mechanism assembly is too tight (insufficient clearance); forklift bearing assembly is too tight; bearing seat ring rotates in the shaft or shell; excessive load; bearing cage or roller fragmentation.
由IKO轴承结构设计参数所确定的钢度，柔度，质量，阻尼等所构成的振动系统在运转条件下将产生与其力学相适应的振动。
The vibration system consisting of steel degree, flexibility, mass and damping determined by the structural design parameters of IKO bearings will produce vibration suitable to its mechanics under operating conditions.
制造加工中的偏差引起的振动，偏差越小，振动越小。钢球表面的圆度、波纹度、表面粗糙度是各轴承零件中对振动影响大的因素，其次为内圈及外圈沟道的形状误差及表面粗糙度，再次是IKO轴承清洁度和润滑剂质量等。
The smaller the vibration caused by deviation in manufacturing process, the smaller the vibration. Roundness, waviness and surface roughness of the ball surface are the most important factors affecting the vibration of the bearing parts, followed by the shape error and surface roughness of the inner and outer raceways, and the cleanliness and lubricant quality of the IKO bearing.
运转条件如安装条件，转速，轴向所承受的载荷方向，量值等。
Operating conditions such as installation conditions, speed, axial direction of load, magnitude and so on.
