Four-row cylindrical roller bearings Four-row cylindrical roller bearings Technical features Description Four-row cylindrical roller radial bearings are used almost exclusively in the rolling stands. They have a lower friction than the other roller bearings and they are suitable for applications where high speeds are required. The reduced radial encumbrance of these bearings lets the adoption of big diameter necks compared to lamination roll. In the four-row cylindrical roller bearings, rollers are driven on the outer ring between integrals edges or not integrals. The inner ring is devoid...

Single-row deep groove ball bearings Single-row deep groove ball bearings Technical features Technical features Inner and outer rings Single-row deep groove ball bearings are the most common type of rolling bearings. Their range of application is very wide. The raceway grooves in both the inner and outer rings have circular arcs of slightly larger radius than that of the balls. Their straight forward basic design has many advantages: Material: Core hardened steel 100Cr6 (UNI 3097 – WNr. 1.3505) or 100CrMn6 (WNr.1.3520) according to the sizes. On request and for special applications they can...

Double-row angular contact ball bearings Double-row angular contact ball bearings Technical features Inner and outer rings Two single row angular contact ball bearings, when duplexed back-to-back so that the inner ring forms one piece, are used to create double row angular contact ball bearings. Alternatively, the bearings may be duplexed face-to-face with the outer ring as one piece. Material: Core hardened steel 100Cr6 (UNI 3097 – WNr. 1.3505) or 100CrMn6 (WNr.1.3520) according to the sizes. On request and for special applications they can be manufactured in case-hardening steel. These...

Double direction tapered roller thrust bearings Double direction tapered roller thrust bearings Technical features Double direction tapered roller thrust bearings allow the realization of compact axial systems. The bearings of this type can support extremely heavy axial loads in both direction and they are insensitive to impacts. Material: Core hardened steel 100Cr6 (UNI 3097 – WNr. 1.3505) or 100CrMn6 (WNr.1.3520) according to the sizes. On request and for special applications they can be manufactured in case-hardening steel. Two types of executions exist: They are mainly used to support...
