Lubrication mistakes

When it comes to lubrication, the most common reasons for bearing failure can be summed up in three words: ‘over’, ‘under’ or ‘wrong’. Here are the the subjects:

• Over-lubrication must be the number one reason for premature bearing failure that occurs in bearing. Too much grease or oil increases the friction and heat for the bearing, leading to seal damage and eventual bearing failure. It is usually easy to spot over-lubrication when it gets to this stage, as there will be grease leakage, an increased temperature during operation or additional noise. 
• Conversely, under-lubrication is almost as bad for bearing longevity, as insufficient amounts of grease or oil leads to metal-to-metal contact that inevitably leads to wear and overheating. The tell-tale signs of under-lubrication are a high operating temperature, unusual vibration and premature wear. 
• Third on the list is using the wrong lubrication for the application or mixing incompatible thickeners or base oils. With different grease or oil viscosities and base types there is no guarantee that they will be able to handle the speeds, loads or temperatures thrown at them during normal operating conditions. The signs of the wrong lubricant use will usually be accompanied by excessive wear, noise, machine or grease breakdown and/or clogged lubrication paths.

Avoiding lubrication mistakes

In order to avoid these common mistakes and get bearing lubrication right，Luoyang jiayu bearing find some way to solve these problems. Firstly, it is important to pay attention to OEM’s specifications for grease type, quantity and lubrication intervals, that are usually based on bearing size, speed, operating temperature, load and environmental conditions. If the manual advice isn’t specific enough, then calculations for grease volume from leading bearing companies are readily available.

Correct lubrication reapplication is equally as important. Manufacturer charts – based on operational conditions, online calculators and lubrication schedule spreadsheets – are good. Also, using ultrasound or vibration analysis, infrared thermography, or checking grease colour changes are useful indicators of lubrication needs. Another thing to take into consideration is lubrication application method. 

Secondly,we use special grease,such as plastic oil(solid oil,),high temperature grease,low temperature grease and special formulated grease,to meet the special requirements of customers.

For high temprature bearings, we use high temperaure grease which can withstand temperature of 180℃。

For grease problems，please contact us.

Galvanized bearings developped by Luoyang Jiayu adopt advanced electro-galvanizing or hot-dip galvanizing technology, forming a uniform and dense protective zinc layer on the surface of bearing rings, rolling elements or cages. This metal coating effectively isolates moisture, air and weak corrosive media, significantly delaying oxidation and rust formation. Compared with standard uncoated bearings, galvanized products show stronger environmental adaptability, stable performance in humid, outdoor, water-contact and mildly corrosive scenes.

With guaranteed precision machining and structural design, galvanized bearings maintain excellent rotation smoothness, high load capacity and reliable dimensional accuracy. They not only extend the service life of equipment but also reduce maintenance frequency and replacement costs, helping users improve operational efficiency and reduce total operating expenses.

At present, galvanized bearings manufactured by Luoyang Jiayu are available in multiple types including deep groove ball bearings, tapered roller bearings, self-aligning bearings and miniature bearings, supporting customized sizes and coating thicknesses according to customer requirements. With high versatility and cost-effectiveness, they are widely used in agricultural machinery, automotive systems, construction machinery, food processing equipment, outdoor facilities and marine hardware.

As industrial equipment develops toward higher durability and longer service life, galvanized bearings will continue to play an important role in anti-corrosion transmission solutions, providing stable and reliable support for the stable operation of various mechanical equipment.

如何选择合适的轴承

虽然选择最佳的轴承类型和组合并非易事，但毫不夸张地说，为了获得理想的设计性能和使用寿命，轴承的选择至关重要。

首先是性能、运行条件、 轴承所要求的环境条件 必须加以考虑。

研究轴承的布置和类型，包括以下部分：

负载方向和尺寸；② 速度；③ 噪音和扭矩；④ 水平轴或垂直轴；⑤ 刚性；⑥ 轴向轴承布置；⑦ 安装和拆卸；⑧ 振动、冲击

所需的额定动态载荷

根据负载、转速和预期使用寿命计算所需的额定动负载。

根据空间和载荷选择合适尺寸的轴承，分析数值并确定是否可以使用标准件。如果是，则需要再次检查基本额定静载荷。

工作负载是否小于额定静态负载？如果是检查运行速度 然后根据以下因素确定配合：①外圈或内圈旋转；②静止载荷、旋转载荷或冲击载荷；③轴和轴承座材料；④固定或膨胀（自由）；⑤高速旋转时离心力导致的内圈膨胀。

同时，还需要考虑密封和润滑问题。

1.镀银金属支架

在某些高速和高温应用中，钢保持架可以镀银，以提高润滑性能和可靠性。镀银可增强轴承的润滑性，使其更加坚固耐用。在润滑剂失效或不足的情况下，镀银层就像一种固体干润滑剂，可使轴承在短时间内或紧急情况下继续运转。轴承保持架的标准镀银厚度通常为 0.003-0.005mm。应用实例：用于高速线材轧机增速箱轴承的镀银保持架。

我们开发的镀银轴承简介

镀银是一种表面处理方法。镀银后，滚动轴承表面光滑，能形成可靠的保护膜，有效防止磨损和氧化。同时，镀银处理还能提高滚动轴承的导热性，使其在高温、高负荷下的性能更加稳定可靠。

镀银轴承的应用

航空航天电机、普通工业机械、真空机械。

2、 滚针轴承套圈和滚动体的镀银处理

在高温或真空要求下，不能使用常规润滑脂。在滚动轴承滚道或滚动体上进行镀银处理，可有效润滑摩擦表面，提高轴承的耐磨性，延长其使用寿命。

全负荷镀银轴承充分利用了轴承的内部空间，允许使用更多的球，大大增加了轴承负荷。采用填充凹口设计时，主要承受径向载荷；采用角接触设计时，使用预拉伸双列角接触轴承可承受双向轴向载荷，应用范围包括航空航天应用中的高温阀门、导弹尾翼支撑轴承等。
