NSK imported bearings in operation for a period of time, it is inevitable that there will be maintenance or damage replacement needs, in the early development of the mechanical industry, the popularity of technical knowledge is not enough, the awareness of operating procedures is not enough, today I will talk to you about the knowledge of bearings.
Our recommended angular contact ball bearing models for you are QJ309, QJ210, QJ310, QJ211, QJ311, QJ212, QJ312, QJ213, QJ313, QJ214, QJ314.
Bearings can be used in: chuck, electrodialysis equipment, plastic granulator, plasma welding machine, glass equipment, bending testing machine, tablet press, flame arrester, fertilizer processing equipment, cutting equipment, and other fields.
When carrying out bearing maintenance, you need to know that in the process of mechanical maintenance, it is necessary to fully understand the technical index information of the bearing code and model of the equipment, and try to rotate the original model to avoid the use of substitute models. In practical work, bearings are often replaced in some equipment, and the replaced bearings are very easy to burn out, which is usually directly caused by the difference in the type of bearings, the use of substitute bearings and the quality defects of bearings themselves.
Because the quality of bearings sold on the market is not uniform, there is the phenomenon of shoddy, long-term use of inferior bearing accessories, long-term wear and tear on machinery and equipment, reduce the service life of equipment. During mechanical maintenance, the rotating bearing should avoid rotating the parts in long-term inventory, and at the same time, the appearance of the bearing should be checked and the function tested, so as to ensure the quality of the bearing.
What is the difference between the metric system and the British system?
The metric system is also called the metric system! The unit is mm, cm, m, inch bearing in inch unit to express the bearing shape size, tolerance, suitable for inch size device.
Inch bearings are suitable for industrial machines of various inch sizes, small rotary machines, etc. 1 inch =2.54 centimeters 1 foot =12 inches =0.3048 meters.
