Radial cylindrical roller bearing with grooves on the outer ring

The inner rings are divided into two parts, on axial direction, which are linked to each other through a shaped steel ring.

They are supplied with execution with lateral plastic seals and are already lubricated with lithium soap grease.

Lubrication can be made both on the outer ring and on the inner ring.

Radial cylindrical roller bearings with grooves on the outer ring have the following characteristics:

The outer rings and the inner rings are manufactured in 100Cr6 steel; sometimes, in some specific working condition, mainly when hard impacts occur, they can be supplied in case-hardened 18NiCrMo5 steel.

They reach hardness degree of 60±2 HRC.

Technical Characteristics

Radial bearings with grooves on the outer ring are manufactured with two rows of cylindrical rollers; they are made of one outer ring and two inner rings with entire massive borders, which act as an efficient axial guide for the rolling bodies. The high sturdiness of the sections, along with the number of rollers inserted in the rolling raceways, allow this series of bearings to achieve a very high load capacity, both dynamic and static.
