Deep groove ball bearing concrete pump truck accessories with silver color and cast steel

Product Description/Features:

Deep groove ball bearing (GB/T 276-2003) formerly known as single-row radial ball bearing, is the most widely used rolling bearing. It is characterized by small friction resistance, high speed, can be used to bear radial load or radial and axial simultaneous action of the combined load on the machine parts, can also be used to bear axial load on the machine parts, such as small power motor, automobile and tractor transmission, machine tool gearbox, general machines, tools, etc.

Deep groove ball bearings are the most common type of rolling bearings.
The basic type of 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 bearing, single row and double row, deep groove ball structure is also divided into sealed and open two structures, open refers to the bearing does not have a sealed structure, sealed deep groove ball is divided into dust seal and oil seal. The dust seal cover material is steel plate stamping, which only plays a simple role in preventing dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the leakage of grease in the bearing.
Single row deep groove ball bearing type code is 6, double row deep groove ball bearing code is 4. Its structure is simple, easy to use, is the most common production, the most widely used class of bearings.

Working principle
Deep groove ball bearings mainly bear radial loads, but also can bear radial loads and axial loads at the same time. When it is only subjected to radial load, the contact Angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of angular contact bearing and can withstand a large axial load, the friction coefficient of the deep groove ball bearing is very small, and the limit speed is also very high.
Bearing characteristic
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 load, but when the radial clearance of the bearing is increased, it has a certain angular contact ball bearing performance and can bear the combined radial and axial load. When the speed is high and it is not suitable to use thrust ball bearings, it can also be used to withstand pure axial load. Compared with other types of bearings with the same size and specification of deep groove ball bearings, such bearings have small friction coefficient and high limit speed. However, it is not shock resistant and is not suitable for heavy loads. [2]
After the deep groove ball bearing is installed on the shaft, the axial displacement of the shaft or the housing in two directions can be limited within the axial clearance range of the bearing, so the axial positioning can be made in both directions. In addition, this kind of bearing also has a certain aligning ability, when relative to the shell hole tilt 2 '~ 10', it can still work normally, but it has a certain impact on the bearing life.
Structure and classification

Bearing construction
The structure of deep groove ball bearings is simple, and it is easy to achieve higher manufacturing accuracy than other types, so it is easy to form a series of mass production, and the manufacturing cost is also low, and the use is extremely common. In addition to the basic type of deep groove ball bearings, there are a variety of variant structures, such as: deep groove ball bearings with dust cover, deep groove ball bearings with rubber seals, deep groove ball bearings with stop grooves, deep groove ball bearings with large load capacity of ball notches, double row deep groove ball bearings.
Bearing type
Deep groove ball bearings are mainly used to bear radial loads, but are also commonly used to bear radial and axial combined loads. Especially when the speed of the mechanical equipment is very high, it is not suitable to use the thrust bearing, the bearing can be used to bear the two-way pure axial load, and there is no maintenance during the work, and it is a kind of bearing with low price and wide use. Deep groove ball bearing models are: deep groove ball bearing (60000 type); Deep groove ball bearing (60000N type) with a stop groove in the outer ring; A deep groove ball bearing (60000-ZN type) with a dust cover on one side and a stop groove on the other side; Deep groove ball bearing (60000-2ZN type) with dust-proof cover on both sides and a stop groove on the outer ring; One deep groove ball bearing with dust cover (type 60000Z); Deep groove ball bearings with dust cover on both sides (type 60000-2Z); One side deep groove ball bearing with sealing ring (type 60000-LS, type 60000-RZ); Deep groove ball bearings with sealing rings on both sides (type 60000-2LS, type 60000-2RZ); Deep groove ball bearing with flange outer ring (F60000 type); One flange outer ring deep groove ball bearing with dust cover (F60000-Z type); There are 11 kinds of deep groove ball bearings with two flanged outer rings with dust cover (F60000-2Z type). [2]
According to the size of the deep groove ball bearing can be divided into:
(1) micro-bearing ---- bearings with nominal outer diameter and size range below 26mm;
(2) small bearing ---- bearings with nominal outer diameter size range of 28-55mm;
(3) small and medium-sized bearings ---- bearings with nominal outer diameter ranging from 60-115mm;
(4) Medium and large bearing ---- bearings with nominal outer diameter ranging from 120-190mm
(5) large bearing ---- bearings with nominal outer diameter ranging from 200-430mm;
(6) extra-large bearing ---- bearings with nominal outer diameter size range of more than 440mm.

Processing form
The processing forms of deep groove ball bearing parts are as follows:
1, multi-process processing: general bearing production needs 20 to 40 processes, more than 70.
2, forming processing: the working surface of the bearing parts are rotary forming surface, suitable for processing by forming method.
3, precision machining: most of the surface of bearing parts should be grinding, grinding size and geometric accuracy are in μm units.

Purpose application
Deep groove ball bearings can be used in transmissions, instruments, motors, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo-yo balls and so on
Installation method

Deep groove ball bearing installation method 1: press into the match: When the outer ring and the bearing seat hole are loosely matched, the bearing can be pressed on the shaft first by a press, and then the shaft and bearing together are loaded into the bearing seat hole. An assembly sleeve made of soft metal material (copper or mild steel) is placed on the end face of the bearing inner ring during press mounting. The bearing outer ring is tightly matched with the bearing seat hole. The bearing can be pressed into the bearing seat hole first, and the outer diameter of the assembly sleeve should be slightly less than the diameter of the seat hole. If the bearing ring is tightly matched with the shaft and seat hole, the installation of the inner ring and the outer ring should be pressed into the shaft and seat hole at the same time, and the structure of the assembly sleeve should be able to hold the end face of the inner ring and the outer ring at the same time.

Deep groove ball bearing installation method 2: heating fit: By heating the bearing or bearing seat, the use of thermal expansion to convert the tight fit into a loose fit installation method. It is a common and labor-saving installation method. This method is suitable for the installation of bearings with large interference. Before hot loading, put the ring of bearings or separable bearings into the oil tank for uniform heating of 80-100 ° C, and then take it out of the oil and install it on the shaft as soon as possible. In order to prevent the inner ring end face and shaft shoulder from fitting tightly after cooling, the bearings can be axially tightened after cooling. When the bearing outer ring is fitted tightly with the bearing seat made of light metal, the hot loading method of heating the bearing seat can avoid chafing the mating surface. When heating the bearing with the oil tank, there should be a grid at a certain distance from the bottom of the tank, or use the hook to hang the bearing, the bearing can not be placed on the bottom of the tank to prevent impurities from entering the bearing or uneven heating, there must be a thermometer in the tank, strictly control the oil temperature should not exceed 100 ° C to prevent the tempering effect, so that the hardness of the ring is reduced.
