Deep groove ball bearings are the most widely used type of rolling bearing. It is characterized by low friction resistance and high speed. It can be used on parts that can bear radial load or combined load acting both radial and axial. It can also be used on elements that carry axial load, such as low-power motors, Automotive and tractor gearboxes, machine tool gearboxes, general machines, tools, etc. buy bearings online click here.

The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls, and a set of cages. There are two types of deep groove ball bearings: single-row and double-row. The deep groove ball structure is also divided into two types: sealed and open. The open type refers to the bearing without a sealed structure. Seal. The dust seal cover material is staamped from a steel plate, which simply prevents dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing. Buy bearings online, click here.

The single row deep groove ball bearing type code is 6 (for example, Single row deep groove ball bearings 634-2RS), and the double row deep groove ball bearing code is 4 (for example, Double row deep groove ball bearings 4208). Its structure is simple and easy to use, and it is the most popular and widely used type of bearing. Buy bearings online, click here.

Deep groove ball bearings mainly bear radial load, and can also carry radial load and axial load at the same time. When it is only subjected to radial loads, the contact angle is zero. When a deep groove ball bearing has an ample radial clearance, it has the performance of an angular contact bearing and can withstand a large axial load. The deep groove ball bearing has a small coefficient of friction and high limit speed. Buy bearings online, click here.

Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. It is mainly used to bear radial loads, but when the bearing radial clearance is increased, it has an absolute angular contact ball bearing performance. It can carry combined radial and axial loads. Although deep groove ball bearing axial load is not common, it can also be used to take the pure axial load when the speed is high, and thrust ball bearings are not suitable. Compared with other types of bearings with the same specifications as deep groove ball bearings, this type of bearing has a low coefficient of friction and high limit speed. But it is not resistant to impact and is not suitable for heavy loads. Buy bearings online, click here.

Deep groove ball bearing application: Deep groove ball bearing can be used in gearboxes, instruments, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo-yo, etc.

Installation method of deep groove ball bearing:

Deep groove ball bearing installation method 1: Press-fit: When the inner ring of the bearing and the shaft are tightly fitted, the outer ring and the bearing seat hole are loosely fitted. The bearing can be press-fitted on the pole with a press, and then the shaft with the bearing They are installed together in the bearing housing hole. On the end face of the bearing inner ring during press-fitting, a soft metal material assembly sleeve (copper or mild steel) is cushioned. The outer bearing ring and the bearing housing hole are tightly fitted. The inner circle and the shaft are For a loose fit; the bearing can be pressed into the bearing seat hole first. At this time, the outer diameter of the mounting sleeve should be slightly smaller than the width of the seat hole. If the bearing ring is tightly fitted with the shaft and the seat hole, install the inner circle, and The outer ring should be pressed into the shaft and the seat hole at the same time. The structure of the assembly sleeve should be able to tighten the end faces of the inner ring and the outer ring of the bearing at the same time.

Deep groove ball bearing installation method 2: heating fit: by heating the bearing or taking a seat, using thermal expansion to change the tight fit into a loose fit. It is a commonly used and labor-saving installation method. This method is suitable for significant interference. For the installation of bearings, but the taking or separable bearing ferrule into the oil tank before heating and evenly heat it at 80-100 ℃, and then take it out of the oil and install it on the shaft as soon as possible. To prevent cooling, the inner ring end face and shaft shoulder. The fit is not tight, and the bearing can be axially tightened after the bearing has cooled. When the outer bearing ring is tightly fitted with a light metal bearing seat, a hot mounting method using a heated bearing seat can be used to prevent the mating surface from being scratched. When heating the bearing with the fuel tank, there should be a grid at a certain distance from the bottom of the tank, or a hook should suspend the bearing. The bearing cannot be placed on the bottom of the tank to prevent sinking impurities from entering the bearing or uneven heating. There must be a thermometer in the tank. Strictly control the oil temperature not to exceed 100 ℃ to prevent the tempering effect and reduce the hardness of the ferrule.
