Why Use An Insert Bearing

Posted December 14, by admin

Y-bearings or more commonly known as insert bearings are commonly used on conveyer and handling systems, machinery made for agriculture, processing and packaging, textile equipment, unique machinery such as car washes, gym equipment and more. There are many benefits to using insert bearings. Some of their main bragging points include having a long service life, being easy to replace, providing increased productivity, and reducing noise and vibration. They are also highly favored due to their convenient uses in a wide variety of applications.

The look of insert bearings is not that different from other bearings, however, there are many variations on the market such as the extension of a locking collar, grub screws, and more. Insert bearings contain a bulging outer ring and an inner ring that is extended. This allows the device to be mounted easily and effectively.

Insert bearings are generally used for strong, heavy applications. Y-bearings are inserted into a “housing” unit that usually comes with the bearing itself. Unlike ball bearings, Y-bearings can be easily inserted during instillation and can be placed directly onto the shaft unit. These bearings will then be held in place by a locking mechanism and are ready to do their job. Because of their wide, or extended inner ring, these will add to a durable, heavy-duty sealing. These bearings will be able to distribute any load over an area that may be created by the inner ring.

1.Basic Introduction to Bearing Types

2. Their Applications

In this article, we'll be talking about types of bearings and their applications. Generally speaking, a reducer bearing is a device used for rotary or linear rotation, while friction and handling motion occurs. In effect, the bearing surface device is capable of rolling, which causes friction between the bearing surface wheel rolls.

When this restraining force is also reduced, it is very easy to move in a rotational or linear fashion - increasing speed and efficiency.

Bearing arrangements include not only rolling bearings, but also bearing-related components such as shafts and housings. Lubricants are also a very important part of the bearing arrangement, as lubricants are required to prevent wear and corrosion so that the bearings can perform their full function.

The seal is also a very important component, and the performance of the seal is critical to the cleaning of the lubricant. Keeping it clean has a profound effect on the life of the bearing.

Such as proper form and design of other components in the bearing arrangement, correct fit and internal clearance or preload of the bearing. Fixtures, appropriate seals, type and dosage of lubricant, installation and removal methods, etc.

Each individual decision affects the performance, reliability and economy of the bearing arrangement. The amount of work required depends on having similar bearing selection experience.

In the case of inexperience, special requirements, or special considerations for the cost of bearing arrangements and any other subsequent profiles, more work, such as more precise calculations and/or testing, is required.

3. Working Mechanisms

For all this weight, the bearing adopts a relative construction: the function of the simple metal function of the surface of the ball - the driving force of the load weight is the force that drives the bearing to rotate. There are different measures, all of which affect power in the same way.

The simple power in the wheel, because of the different bearings on the bearings, while sliding on the bearings and pushing in the way of rolling or rolling obviously affects the bearings in a completely different way. The whole process of carrying (loading the tire) on it (like trying to put the tire on a child now) should be subject to full force (on the tire), which is called a thrust. The bearing that supports the bar stool is just an example of a bearing that carries thrust.

Many bearings are susceptible to radial and axial loads. For example, car tires experience radial loads when driving in a straight line: the tires roll forward in a rotational fashion due to tension and the weight they support. However, when the car rounds a corner, it experiences thrust loads because the tires are no longer just moving in a radial fashion and the cornering forces are heavy on the bearing flanks.

There are many different bearing types designed to handle radial loads, thrust loads or some combination of the two. Since different applications require bearings designed to handle specific loads and different weights, therefore the differences between bearing types relate to the type of load and the ability to handle weight.

4. Bearing Types of Seal and Their Uses

In the second part of types of bearings and their applications, we’ll be talking about bearing uses. In terms of its function, it should be a support, that is, it is used to bear the shaft in a literal interpretation, but this is only a part of its function. The essence of support is to be able to bear radial loads. It can also be understood that it is used to fix the shaft. Bearing quick and easy automatic selection is included. It is to fix the shaft so that it can only rotate, and control its axial and radial movement.

In order to reduce this effect, good lubrication must be achieved on the bearings of the high-speed shaft. Some bearings have already been lubricated themselves, which are called pre-lubricated bearings. Most bearings must have lubricating oil, which is responsible for not only increasing energy consumption due to friction at high speed, but also terrifyingly easily damaging the bearings. The argument to convert sliding friction into rolling friction is one-sided, because there is something called a sliding bearing.

(3) Lubrication Method

Bearing lubrication methods are divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to select a lubrication method suitable for the conditions of use and the purpose of use. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing. Compare the advantages and disadvantages of grease lubrication and oil lubrication.

When lubricating, pay special attention to the amount, whether it is oil lubrication or grease lubrication, if the amount is too small, the lubrication will not fully affect the bearing life, and if the amount is too large, it will cause large resistance and affect the speed.

(4) Seal

The seal of the bearing can be divided into two types: self-contained seal and external seal. The so-called bearing self-sealing is to manufacture the bearing itself into a device with sealing performance.

Such as bearings with dust cover, sealing ring and so on. This kind of seal takes up little space, is easy to install and disassemble, and has a relatively low cost.

The so-called bearing plus sealing performance device is a sealing device with various performances manufactured inside the installation end cover, etc.

Bearing seals are divided into non-contact seals and contact seals.

Among them, the non-contact seal is suitable for high-speed and high-temperature occasions, and has different structural forms such as gap type, labyrinth type and gasket type. Contact seals are suitable for medium and low-speed working conditions, and commonly used structural forms such as felt seals and leather cup seals.
