Q:What's the difference between 6000-6012 and 6200-6212 in deep groove ball bearings?

This can be known by checking the code number6 means deep groove ball bearingsThe second bit indicates the width of the series. The model you call here is a narrow series, omitting 0The third digit indicates the diameter series code, of which 0 is light, and the 2 is light. (that's what you ask.)Position four or five is the inner diameter code, and your number is 12, or 60mm

Q:How to use the feeler of deep groove ball bearing clearance?

Taking the average may not be appropriate because we can only know the extent of the gap, but it can not be sure that it is the middle of the two values. Personally, I think it's more reliable to give a scope.

Q:Why is the rated speed of deep groove ball bearings (reference speed) greater than the limit speed, greater than almost double?. Only deep groove ball bearings are like this? Why?

The maximum speed of various bearings can be checked by table, and the ultimate speed of deep groove ball bearings is very high. But, "why is the rated speed of deep groove ball bearings (reference speed) greater than the limit speed, greater than almost double?". Only deep groove ball bearings are like this?" Where does that come from? No, it will damage the bearings very soon.

Q:A deep groove ball bearing model with an outer diameter of 8.5 cm and an inner diameter of 4.5 cm

Internal diameter 45mm external diameter 85mm wide 19mm corresponding model 6209

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:What does "deep groove ball bearing suffix" "MA" mean?

SKF deep groove ball bearings, the basic model suffix MA means steel cage, outer ring boot

Q:Just learned in the selection of motor bearings, in addition to the deep groove ball bearing, the rolling bearing to meet the following conditions: 1. the C3 clearance speed is higher than the reference speed bearing 70%; so choose C3 clearance of deep groove ball bearings at what time the 2. temperature greater than 10 DEG C when the inner and outer rings? Younger brother every time with the coefficient of linear expansion and temperature rise to reduce the amount of clearance, and then refer to the bearings and shaft and bearing seat to determine the use of clearance, so that there are other deficiencies? Request for comment

According to the estimation, the radial clearance reduction due to interference is chosen

Q:At present only rough calculation is used to choose what kind of bearings. Load 5 ton car, four wheels, need four bearings. What kind of bearings need radial load?.

I can't, but I know that the selling of bearings will be, if it is the standard bearings, he has a parameter, you say you want to buy Bearings, and then ask someone to help you check it

Q:What is the width tolerance of the 6 degree deep groove ball bearing B?

The inside diameter section is different, the tolerance is different. The state has standards and can be downloaded free of charge.

Q:Deep groove ball bearings 206 medium 206 what does that mean?
