What is the bearing
Bearings are parts that cause the movement and rotation of two or more parts on each other and are so important that currently the life of industries depends on their existence.
Bearings with a significant reduction Friction makes it possible to move two metal parts without corrosion, wear, wear and tear.
Bearings generally consist of an inner ring, an outer ring, a holding rack and a number of balls. They are made spherical and the way it works is that the shaft is placed inside the inner ring and during rotation, instead of the two parts directly contacting each other, the balls and the lubricant transfer the movement between them and prevent it from getting hot. and prevents the depreciation of parts.
What is Rollering?
Rolling bearings, like bearings, are considered rolling bearings, and their job is to create frictionless movement of two parts on each other. and its difference with bearings is that rollers are used in the parts instead of balls. Due to the use of metal rollers, roller bearings are able to withstand more load than bearings, although they have a lower speed tolerance.
What is Nidellering
Needle bearing or needle roller bearing is one of the most widely used types of roller bearing in the industry. Due to their unique structure, needle bearings can withstand radial loads well, and due to their delicate construction and design, they are considered the best option for small devices and limited spaces. Needle bearings, like other roller bearings, are made of inner and outer rings, shelves and metal rollers, with the difference that needle bearings are metal rollers designed in the form of very long and thin cylinders, and a large number of them are placed in the shelf. .
Needle bearings are very accurate and take up little space; Therefore, they are widely used in industries such as airplane construction and space structures. Also, needle bearings are used in the manufacture of precise control and measurement tools such as clocks and calipers.
What is oil and grease
Oils and greases are included in the category of lubricants and are considered important and consumable components of mechanical devices.
The role of grease and oil in machines is very important because without them, metal parts that At high speed, they heat up in less than a few seconds and cause a lot of damage.
Greases and oils are different from each other, and the designer selects one of these two for each machine and part based on their needs. It uses lubricant.
