Cylindrical Roller Bearings SKF NU312 ECP

The SKF NU312 ECP cylindrical roller bearing is an open idler bearing with a 60 mm bore that can withstand high radial loads.

The NU312 ECP cylindrical roller bearing belongs to the single-row radial roller bearing series and is characterised by its optimised internal design in the SKF Explorer series. With dimensions of 60x130x31 mm, this open roller bearing accommodates high radial loads. The integrated polyamide cage guides the cylindrical rollers with low friction. As the bearing is unsealed, it can be flexibly integrated into existing oil or grease lubrication circuits.

What is the NU312 ECP cylindrical roller bearing suitable for in operation?

The NU design functions purely as a non-locating bearing. The design features two fixed flanges on the outer ring, whilst the flangeless inner ring can be removed from both sides. This allows the bearing to compensate for axial length changes in the shaft caused by thermal expansion without inducing stress within the bearing. Typical applications include bearing arrangements where shafts must be guided precisely and axial displacements accommodated without inducing stress.

What properties does the polyamide cage offer during assembly?

The polyamide material reduces the mass of the rolling element set and dampens vibrations. The component is suitable for operating temperatures ranging from –30 to +120 degrees Celsius. As the inner ring can be removed completely, the inner and outer rings can be fitted separately. This simplifies installation and maintenance. The bearing has standard radial clearance and mounting dimensions in accordance with tolerance class P0.
