Q:How are deep groove ball bearings made?
Method for manufacturing deep groove ball bearing:1, with the bearing steel cutting processing into inner ring and outer ring, through, blanking, trenching, heat treatment, internal and external grinding, flat magic, grinding, put into the ball with a cage separately, oiling, packaging, completed.2, put the outer ring, and then put the inner ring. Here, the inner ring is placed inside the outer ring and then placed into the ball. Make sure that the ball is secured to the cage.3, in the bearing industry, the steel ball placed in the middle of the outer ring, this process is called "assembly" or "set"". Prepare the inner and outer rings, place the inner ring on one side, put the ball into the ball, divide the ball, separate the ball evenly with the ball separating device with small claws, place the cage and rivet the two holders.4, in actual production, there are full loaded, usually with a ball loaded gap. It can be seen that there is a ball gap on one side, and the steel ball is filled from that gap, but the bearing is less capable of axial load and less used.5, deep groove ball bearings are mainly divided into inner and outer rings, steel ball, cage, sealing ring (dust cover).6 deep groove ball bearings are the most common types of rolling bearings. A basic deep groove ball bearing consists of an outer ring, an inner race, a set of steel balls, and a set of retaining structures. Deep groove ball bearings are of two types, single row and double row. The deep groove ball structure is divided into two kinds of sealing and open structure. The open type means that the bearings are not sealed. The sealed deep groove ball is divided into dustproof sealing and oil tight sealing.
Q:To withstand 5000KG radial force to use much deep groove ball bearing.
5T ah, 4 bearings, 5T, 2, 6308, and together, installation can meet the requirements. A single set of 6308 is not enough!
Q:What are the characteristics of double row deep groove ball bearings?
Double row deep groove ball bearing with radial single row deep groove ball bearing 1.62 times higher than the carrying capacity, suitable for application in bearing configuration load capacity of a single row deep groove ball bearings of the double row deep groove ball bearing besides bearing radial load, also can withstand the axial load effect in two directions.
Q:Use of deep groove ball bearings?
Deep groove ball bearingThe most representative rolling bearings, wide range of usesCan bear radial load and two-way axial loadIt is suitable for high speed rotating and low noise and low vibrationSealed bearing with steel plate dust cover or rubber sealing ring is filled with proper grease in advanceThe outer ring with a stop ring or flange bearings, that is easy to axial positioning, and easy to install inside the housingThe size of the maximum load type bearing is the same as that of the standard bearing, but there is a loading groove in the inner and outer rings, which increases the number of balls loaded and improves the rated loadMain retainer: steel plate holder (waveform, crown)... Single row; S shape... Double column)Copper alloy or phenolic resin cutting cage, synthetic resin forming cageMain application: Automobile: rear wheel, transmission, electrical partsElectric: General Motors, household appliancesOther: instrumentation, internal combustion engines, construction machinery, railway vehicles, handling machinery, agricultural machinery, various industrial machinery
Q:Deep groove ball bearing 629Z code, how to resolve?
629z Size 9 * 26 * 8Z are all dust caps with sealing ringsZ stands for iron coverZZ stands for double sided iron cover or double iron coverGenerally, sealing is better than sealing with ironSo the price is generally cover you Kunshan Si Ian Bearing Co. Ltd to become a trading company bearing considerable scale. The company and the FAG Hongkong technology center has established a good reputation, in order to better service and established in the mainland sales window, has ten years of experience in sales of bearings,
Q:What's the difference between the rubber cap and the iron cover of the deep groove ball bearings?
Iron cover only dustproof, waterproof rubber cover, dustproof and waterproof
Q:Deep groove ball bearings on the outer ring processing two grooves, and then add two aprons play what role?
The two aprons act as an oil seal.The bearing operation will have friction, will generate heat, causing damage to the bearing wear, reduce friction, ensure the normal life of the bearing, the bearing operation need lubrication, lubricating oil heating after thinning, if there is no oil seal oil blocking oil will flow away, so to install oil seal at the ends of the bearing.There are some bearing does not own seal, such as automobile gear box bearing, but some of them are soaked in oil in the oil pump work or keep hydraulic lubrication to them, so they do not need to seal. In addition, some machinery, such as parts of the motor, the ends of these motors are equipped with metal oil seals, and then the bearings do not need to bring their own oil seal.Another function of the oil seal is to block the outside debris into the bearing (track), such as sand, iron particles into the bearing track, it is easy to cause damage to bearings.
Q:Deep groove ball bearing production process
The first step is forging forming, annealing, and machining, heat treatment and, to 58-62 degree, then the rough grinding, fine grinding or tempering stability, ultra precision grinding, reach the oil standard, then the rolling body and the inner and outer ring, a retainer, antirust oil - Packaging - hair the goods. Indicate that GCR15 or GCR15SIMN material is selected according to the thickness of the bearing
Q:What are the benefits of SKF deep groove ball bearings?
1, under normal conditions, SKF deep groove ball bearings and hydraulic power efficiency of the same bearings, but more mixed lubrication bearings higher;2, radial clearance is relatively small, radial angular contact bearings can be pre tightened, can be used to eliminate pre clearance clearance, high precision operation;3, for the same size of the shaft diameter, SKF deep groove ball bearings wider than the sliding bearing, can make the axial structure of the machine compact;4, most bearings can be subjected to radial and axial loads simultaneously, so the bearing assembly structure is simple;5 、 consumption of lubricant less, easy to seal, easy maintenance;6, no useful non-ferrous metal;7, a high degree of standardization, batch production, low cost;
Q:What does "6208" in deep groove ball bearing 6208 GB/T 276-1994 mean? Ask God for detailed explanation and dimensional description.
Oh, on the ordinary deep groove ball bearings, 6208 diameter, 40, outer diameter 80, thickness 18
