Specification of rolling mill bearings:
Metallurgical Rolling Mill
Require high precision, large rated moving load, and high maximum rotation speed. By adopting the new technology of material processing, for instance, the Bainite Treatment, CNBM has successfully manufactured bearings of long service life that are highly fatigue resistant and impact resistant. The high and stable product quality has helped CNBM gain good reputation among more than 100 large and medium-sized steel enterprises all over China.
They types of bearings made by CNBM for the metallurgical rolling mills are: single-row, double-row, triple-row, quadri-row cylindrical roller bearings, deep groove ball bearings, single-row and double-row angular contact bearings, four-point contact ball bearings, single-row and double-row tapered roller bearings, fully-loaded cylindrical roller bearings(roller wheel bearings), and non-standard bearings of large sizes.
- Q:What are the E and Y values of the 30209 bearings of tapered roller bearings?
- The shoulder of the positioning shaft is positioned; the transition shaft shoulder is provided for the disassembly of the parts on the shaft or the prevention of the stress concentration. But the axial shoulder will inevitably increase the diameter of the shaft, and the shoulder of the axle will change due to the stress concentration.
- Q:Tapered roller bearings. Are the rollers tapered?
- The frustum of the cone can be seen as a right angled trapezoid revolving around the right angle, and the top is a circle. Can also be seen on top of the tip is tapered off, the tapered roller head is not a round face
- Q:that is to say, the taper head is the face and the back is the back
- When you remove the outer ring of the tapered roller bearing, you will see that the components of the inner ring cage are large and smallLook at the axial force you are using. The direction of the axial force in that direction is consistent with the direction of the small one,
- Q:What are the general uses of tapered roller bearings?
- At the time of greater radial load and axial load
- Q:you master good! Ask a question about the use of tapered roller bearings: a mechanism using a double row tapered roller bearings, but did not buy this model, can use two single row tapered roller bearing together instead of double row?
- 2, the clamping way is: double row bearing inner ring is double row, or outer ring double, determines when you install the inner ring or outer ring is clamped, clamped, if you want to replace with the two row, when combined with the clearance you need to consider the ring, you should adjust the clearance and is placed on the inner ring, or on the outside, too that depends on your way of clamping;
- Q:There are many kinds of tapered roller bearings, because of work requirements, test the external size is qualified, I want to make a test, to test the bearing is qualified, mainly inside and outside diameter and inside and outside the ring height tolerances, diameter ranging from 50mm--80mm, score less, look forward to your help, I thank you there are 322163311532215 main bearings, 313113002
- This is not easy yet. Do you think it's possible to make a standard check instrument yourself?!
- Q:Tapered roller bearings, 70 in diameter, please tell me the model number
- What about outside diameter (D) and width (B)? You didn't say?.Following are all series of codes and sizes for tapered roller bearings (single column and double row).

- Q:Why is the cage of tapered roller bearings loose?
- You can come up with the relevant standards, must belong to the bearing standard parts, as long as you meet the standard requirements of the bearing can be spread!
- Q:The installation of tapered roller bearings
- 3, bearing ring roller contact surface is cone surface or cylindrical surface?Cone surface, in order to be able to bear both axial force and radial force
- Q:Tapered roller bearing: Bearing expert why burned or locked
- Shaft tolerance is relatively small and fine head, the inner shell inside and nose has obvious signs of friction. If there are traces of friction on one side or on both sides of the inner shell, there is an abnormal contact with the inner shell of the bearing and the friction of the inner shell of the bearing.2, the inner shell shell burning marks are not serious, roller black even deformation, generally is the inner shell or casing tolerance, Ambassador bearing gap smaller, and even negative tolerance caused by burning. Or in the maintenance of the bearing selection is not correct, you can use large clearance bearings.3, the shell burned seriously, the inner shell, roller are no obvious changes, you can observe whether the shell has traces of friction. There are traces of friction on the outside, and it can be considered that the tolerance between the bearing shell and the shaft is insufficient, which results in abnormal friction caused by the slipping of the housing. If there are traces of friction on one side or on both sides of the shell, there is an abnormal contact between the component relative to the bearing housing and the bearing housing, and the heat generated by friction will be burned out.
