Introduction to the needle thrust bearing There are many rolling elements like the roller bearings and the ball bearings. Within the roller family come the spherical, tapered, cylindrical and the needle bearings. In the whole roller bearing family, the needle bearings are the smallest in size and they are the lightest in the weight. This is the major reason why these bearings are the most popular bearings and are used by the wide number of applications. The needle thrust bearing have got this name from the high roller length-to-diameter ratio and also due to the operational characteristics of the bearings.

The applications that require very less weight and space prefer them the most. Features of the needle thrust bearing The China large industrial fan suppliers needle thrust bearings must have many essential features due to which these bearings have very high usage in the industry. The features are as follows: The capacity of the bearings is very high in compare to the single-row ball or some other same type of roller bearings. The taper roller bearing design is such that it is able to handle a shaft that is more rigid and which is larger.

The rolling characteristics are excellent and there is a very small cross section. The cost of these bearings is very low. The drawn cup type thrust bearings are the cheapest out of all. Factors affecting the performance of the needle thrust bearings The very important factors that affect the performance and efficiency of the needle thrust bearings are listed below: 1. Lubrication The basic lubrication that is being preferred is the oil lubrication. The oil lubricant acts as a coolant and all the contaminants that are being added are removed. The splash of oil and the positive feed is the best method.

The bearing can be lubricated with grease if required. By fitting of the shaft, relubrication can be done. 2. Raceway surfaces If the raceway material is very high and the geometrical properties are best then good performance will be gained. 3. Hardness The needle bearing catalog has the ability to use the surfaces that are mating to the inner raceways as well as the outer raceways. All the acceptable treatments can be the case hardening and the through hardening. 4. Finish To maintain a good lubricant film, it is essential to have the good raceway surface.
