Universal Joint Manufacturer in India

1. 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 universal- joint 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.

2. Secondly, the universal-joint cross-head needle bearings cannot rotate along with the steel bowl and cross shaft neck when at work. The rolling ability of the Albany grease is poor, so the new film cannot be formed immediately after the destruction of the old one. Thirdly, the Albany grease is a mixture of oil and calcium soap. When it is used, due to the lubricant evaporation and deterioration, the Albany grease will become a hard calcium soap that does not have a lubricating effect itself. Besides, it also hinders needle rollers to roll on the shaft neck. All of these greatly accelerate the wear of the bearing products. In order to change this wrong method and extend the service life of universal joint cross-head needle bearings, the following maintenance methods are recommended. Cardan Shaft Manufactutres in India is one of the leading and the best Cardan Shaft Manufacturers . They not only manufacture but also have export houses of Cardan shaft, Universal Joint, Universal Coupling and they really provide the best services to their clients. First of all, you should remove the needle bearings and clean them thoroughly. And then clear all the residual grease (boiled or washed with the gasoline). After that, you can soak them into the gear oil for about 2min-l0min, and then you can install them. Additionally, you can use the special hydraulic filling equipment to lubricate the universal-joint cross-head needle bearings regularly.
