Cylindrical rollers for conveyor belts
The inner ring is manufactured in case hardened UNI 100Cr6 steel with maximum hardness
degree 60-
Protection system has steel shields made with elastic layered steel rings.
Grease lubrication is made through a groove on the inner distance ring.
Considering the application of the cylindrical rollers, C.R. can supply execution with radial clearance C3/C4 and stabilizing heat treatment up to 250° C, on request.
The execution with cylindrical rollers is generally used with high radial loads, as this can absorb distortions and dilatations.
In comparison with the execution with tapered rollers, this execution is used near high heat sources.
The entire borders obtained in the outer ring allow the absorption of average axial thrusts.

The outer ring is usually manufactured in cementation UNI 16NiCr4 steel and reaches
hardness degree of 60-
