CYLINDRICAL ROLLER BEARINGS
Generally the cylindrical rollers bearings have the following technical characteristics:
The outer ring is usually manufactured in case-hardening steel 16NiCr4/ 20CrMo (UNI 7846) steel for low capacities and 18NiCrMo5 (UNI 7846) for high capacities.
These steels can reach hardness degree of 60-2 HRc. The profile of the outer ring is available in three different executions:
1) Ring with outer surface without borders
2) Ring with one guide border on the outer surface
3) Ring with double guide border on the outer surface
The inner ring is manufactured in hardening and tempering steel 100Cr6 (UNI 3097) and can reaches hardness degree of 60+2 HRc.
Grease internal lubrication is made through a groove and holes in the inner ring surface. The protection system can be made with steel shields or with elastic layered steel rings. Considering the application of the cylindrical rollers, we can supply execution with radial clearance C3 or C4 and stabilizing heat treatment up to 250°, on request
