Bearing Industrial shanghai Machine tool used Cylindrical roller bearing NU248M
Bearing Industrial shanghai Machine tool used Cylindrical roller bearing NU248M introduction :
Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools. Some cylindrical roller bearings have no ribs on either the inner or outer ring, so the rings can move axially relative to each other. These can be used as free-end bearings.
There are different types designated as NU, NJ, NUP, N, NF (for single-row cylindrical roller bearings), NNU, and NN (for double-row cylindrical roller bearings depending on the design or absence of side ribs). The outer and inner rings of all types are separable .

Know more about our bearings :
1. Inspection of bearing and judgment :
In order to determine whether removing bearings can be used to check after the bearings clean, carefully check the roller surface, scroll, status of the mating surfaces, wear of the cage, the increase in bearing clearance and there's no falling damage, abnormal size precision. Non-separation of small ball bearings, supporting inner rings with one hand horizontally, rotate the outer ring to confirm in a smooth rotation State. Tapered roller bearings are separable bearings, rolling element and the Raceway in the outer ring can be respectively checked. Larger bearings cannot rotate, check rolling element and the Raceway, cage, sidewall surface appearance. the importance of as high as possible shall be carefully inspected.
2 .Bearing damage reasons analyse :
- Bearing installation methods :
- Want to just before installing, just open the bearing package. Oil lubrication, ordinary or having to clean, however, instruments or high speed bearings, to wash with clean oil, drop the coated bearings rust inhibitor. General lubrication of grease, no cleaning, fill the grease directly. Furthermore, into the bearings with grease, no cleaning directly. Bearings removed the rust inhibitor, rust, so cannot be placed aside.
- When installing to a shell, General clearance and interference in the outer ring, usually press onto, or have installed after the cooling method for shrink fit. Use dry ice as a cooling agent, shrink fit occasion, moisture in the air will condense on the bearing surface. So it took appropriate measures against corrosion. Installation method of the bearing, bearing structure, fit, vary depending on the conditions, in General, due to rotate, so the inner ring interference fit is required. Tapered bore, installed directly on the tapered shaft or sleeve installation. Bearings with a cylindrical bore, press onto, or multiple-use and charging methods.
