The types of bearings in terms of shape
Bearings have different types, each of which can be divided into different categories based on a feature. One of these categories is based on appearance, which are classified as follows. But each of them offers different functions according to their shape.
Deep groove bearings
Deep Groove Ball Bearings is one of the most widely used types. The presence of a deep circular groove in each rim with a radius equal to the radius of the ball used is the reason for the name of this product. The existing grooves make the deep groove bearing able to withstand high radial loads along with a small amount of axial forces. In addition, this bearing has the ability to withstand radial and axial compound loads. In order to get to know the types of loads applied to bearings; We suggest you read our article in this regard.
The number and sizes of balls used in this type depend on the elasticity of the rims. Deep groove ball bearings are produced in different types of single row groove, double row groove and stainless steel groove. Another type has a deep groove on both sides of the felt or rubber bowl, which increases the speed of this type of bearings due to the distance between the felt bowl and the inner ring. The ease of installation of this product has made it useful in many industries. According to its type and classification, deep groove bearings are most widely used in agricultural machinery, conveyors, construction machinery, automotive, steering box, dynamo, plus, car rear wheels and idlers.
Angular call bearings
This type of bearing has a structure similar to the groove type; Their only difference is in the inner and outer rim and the type of angular movement between the rims. In addition, the rings in the angular contact bearing are moved relative to each other. Often, two rows of balls are used in the production of this type of bearing. In this product, it is possible to bear radial and axial load at the same time. The contact angle of the inner ring has a direct relationship with the bearing capacity of the axial load in the angular contact bearing and an inverse relationship with the bearing capacity of the radial load. Angular contact bearings are most commonly used in car gearboxes. In addition, this type of product is also used in CNC lathes, high-speed milling machines, industrial machinery and equipment that require high speed and power at the same time.
Self -setting bearings
Another type of self-aligning ball bearing is Self-Aligning Ball Bearings, which has many applications in various industries. This type of bearing has two rows of balls and a common outer ring. This product can automatically perform the necessary adjustments when there is a deviation and misalignment in the bearing shaft due to the curvature in the ball groove. Self-adjusting bearings are often used for places that increase or decrease the angle and deviation after a while due to the creation of various factors. The most common application of self-adjusting bearings is in agricultural machinery, conveyors, etc.
Complete ceramic bearings
One of the most common bearings produced and used in various industries is the full ceramic bearing. As its name suggests, all its components are made of ceramic (silicon nitride or zirconia). This part has a smooth surface and uniform dimensions, which causes less friction and ultimately less energy is spent to turn the wheels or the crank. Full ceramic bearings have special features such as electrical current insulation, high speed, long service life, cost-effectiveness, wear and corrosion resistance, light weight, rust resistance, less friction, chemical resistance and suitable For high temperatures up to 1000 degrees Celsius. For this reason, it is most widely used in industries such as aerospace, motorcycle and racing car production, and industrial electric motors.
Ceramic hybrid bearing
This type of product is made with a steel body and ceramic balls. Ceramic balls show good performance when high speed is required. The ceramic used in the balls is lighter than steel and also has a higher degree of hardness than steel. Due to the non-porous structure of ceramic balls, there is practically no friction when moving in the bearings and they produce faster rotation than steel balls. Among the most important features of ceramic hybrid bearings are high speed, increasing the useful life of the device, low weight, high hardness, high efficiency and multi-purpose use in all types of machinery. The most common use of this product is in the aerospace industry, electric motors, racing vehicles, laboratory equipment, etc. In fact, this type of bearing is the best choice in all cases where speed, less friction and longer life are needed.
