What Are Our Concerns About Bearings（12）

Q1:What are the dimensions of 6002Z bearing, 6804A bearing and 6906Z bearing  

6002Z: inner diameter: 15, outer diameter: 32, width: 9  

6804A: Inner diameter: 20, outer diameter: 32, width: 7  

6906Z: INNER diameter 30 outer diameter 47 thickness 9  

Q2:May I ask what type of bearing is 35 outside diameter and 17 inside diameter?

There should be two kinds of different thickness  

17 * 35 * 8, 16003  

17 * 35 * 10, 6003  

Q3:324EC bearing type?  

The 324 is an old model  

The new model is 6324, 7324, 2324  

Both have an inside diameter of 120, an outside diameter of 260 and a thickness  of 55  

You have to determine whether it is a deep groove ball bearing, cylindrical roller  bearing, or angular contact bearing  

Q4:Double row bearing 24030 has long internal and external dimensions  

Model: 24030 – E1  

Brand: FAG bearing  

Product category: self-aligning roller bearing  

Basic dimensions  

Inside diameter: 150 outside diameter: 225 Width: 75 mass m  

Material kg: 10.4  

Q5:Bearing speed is very slow but radial force is very large, which kind of bearing is applied?  

High temperature cylindrical roller bearing.  

The specific model can be checked in the mechanical design manual. If a bearing  cannot meet the requirements, multiple bearings can be used.  

Q6:Bearing size outer diameter 47mm, inner diameter 19.5 thick 14mm is what type?  

Bearing type is regular, the last two times 5 is the inner diameter, the first two    should be the outer diameter, the first number is the bearing style.  

For example, 60306 (or 6306), this bearing is a common steel ball bearing, bearing diameter, that is, bearing inner diameter is 30MM  

And the first number is 7, is the kind of trapezoidal bearing, two together.  There  are many more.  

Q7:Needle roller bearing size 50 80 45 what model is it?  

Needle roller bearing inner diameter 50 outer diameter 80 width 45  

NA4010 50X80X30 NAV4010 50X80X30  

NA6911 55X80X45 RNA6911 63X80X45 NA6911A 55X80X45  

Q8:Are the dimensions of bearings 6311 and 6411 the same?  

The inner diameter and outer diameter are the same. The size of the steel ball    6411 is larger than that of 6311, and the height is a little higher.  

Q9:A look at the bearing type you know how to distinguish the size of   the bearing? 

It is generally judged according to the last two digits of the bearing model:       00–10MM  

01–12MM  

02–15MM  

03–17MM  

Starting with 04, the last two digits are multiplied by 5, the inner diameter.  For example, the inside diameter of 6321 is 105MM = 21×5  

Q10:What is the bearing size of HMK2018L?  

This model is the Japanese NTN bearing code, it is a heavy series of stamping outer ring needle roller bearings, inner diameter 20, outer diameter 27, height 18, with a seal ring

Q11:Tianjin imported bearing supplier  

The standard supply range of insulated bearings includes the most common sizes and variations of bearings: single row deep groove ball bearings, single row cylindrical roller bearings.  

If you need to list the type and size of bearings or smaller bearings than listed, we recommend using SKF mixed ceramic bearings

Q12:Several problems about bearing design?  

Bearing belongs to standard parts, as long as the inner diameter, outer diameter, width and type are determined, then what is determined, do not need bearing factory design.  The advantage of standard parts is that everything can be mass-produced, so the cost is very low.  The thickness of the outer ring, the radius of the outer   ring, the radius of the inner ring, the thickness of the roller and the number of   rollers are all standardized.  If you want a non-standard ball bearing, for example, you may not have available parts and have to customize or make your own.  

If you must have non-standard parts, then the bearing factory can design and    manufacture for you, but the cost is not easy to say, according to your number,   may be more than ten times (the number is larger) to one hundred times (the    number is less) the difference.  

Q13:May I ask what is the meaning of the bearing model DQY22-225B?  

Model Description:  

DQY 22 —225 B  

DQY– End cover type spherical plain bearing  

No. 22 – bearing  

Bearing bush nominal diameter (mm), inner diameter.  

B– Structural form (TYPE A, type B)  

Type B is a self-aligning end cover spherical plain bearing with an air seal to balance the air pressure and prevent the low pressure inside the motor from allowing oil and gas to escape through the floating seal ring.  

Q14:What does bearing type CK+H mean?  

Bearing model CK+H means bearing with accessories, CK before “+” is the suffix of bearing code, such as 22208CK self-altting roller bearing, its letter C stands for    inner ring without retaining edge, active retaining ring, stamping cage, symmetrical  roller, reinforced;  K represents the inner ring conical hole, the taper is 1:12;  The H after “+” is the bearing attachment — the type code of the fixed sleeve, such   as H308.  

Q15:Do you have any double row tapered ball bearings of model 32008?  

32008 tapered roller bearing size is: 68mm×68mm×19mm  

A diallel cone with equal inner and outer diameter is 352008
