Maintenance Methods for Universal-Joint Cross-Head Bearings Lubrication is necessary for almost every mechanical part. There are various kinds of lubricants. So choosing the right lubricant for the products becomes quite important. Universal-joint cross-head bearings should be lubricated with gear oil. But generally, these bearings are lubricated with grease. Actually, it is wrong to use this lubricant which can lead to the early damage of a large number of cross shaft needle bearings.
Cardan Shaft Manufactutrers in India is one of the leading and the best manufacturers. They not only manufacture Cardan Shaft, Universal Coupling but also are well known for manufacturing Universal Joint Manufacturer in India and they really provide best services to their clients. When dismounting, you can find that shaft neck and the needle severely lacks oil. Why does this phenomenon appear? It is because that the lubricating nozzle of universaljoint cross-head needle bearings is a common grease nipple. And people will misunderstand that they should be filled with grease. In fact, it is very difficult to lubricate the needles with a grease gun. When compare the lubrication effect to the cross shaft needle bearings, the gear oil is far better than the Albany grease. The reasons are various. Firstly, the universal-joint may bear large torque and cyclic loading, but the oil slick of Albany grease is not tough enough. As a result, it cannot form a good oil slick at the friction surface between the bearing and the shaft neck.
