Double row spherical roller bearings

The outer ring of this type of bearing has a spherical raceway that allows angular movement of the rings. This means that the bearing can accept high degrees of misalignment. Its internal design enables it to withstand very high radial loads and axial loads. Variants with a tapered bore allow fitting using an adapter sleeve. This type of bearing is particularly suited to heavy mechanical applications where it is difficult to align the seats and radial loads are high. It is well suited to severe operating conditions, involving impact or vibration (crushers, vibrating screens, heavy handling machinery, etc.).

Spherical roller bearings were the first to benefit from the Premier system. The tests carried out on these new products showed very significant gains: +18% for the load capacity, +75% minimum life duration. The « Premier » brand name is clearly visible on the specific packaging created for the launching of the range. The bearing itself bears a specific marking. In addition, to fight against counterfeits, all SNR standard bearings benefit from a new holographic label comprising several safety levels. These multiple identifications express the difference between SNR « standard » and products without any guarantee. Gradually, the Premier specification will be applied to all the brand’s bearings.
