E Series

Spherical roller bearings offer an attractive combination of design features, which are making them irreplaceable in many demanding applications. • Self-aligning Spherical roller bearings accommodate misalignment between the shaft and housing without increasing friction or reducing bearing service life. • Very high load carrying capacity Optimized internal geometry within the available cross section provides maximum radial and axial load carrying capacity. • Robust Insensitive to misalignment caused by shaft or housing deflections as a result of heavy loads. • Easily fitted for loads in all directions The bearings are non-separable and ready to install, having a choice of mounting methods. • Simplify the application The favourable design characteristics combined with simplified mounting procedures enable more efficient and compact machine designs. E design To facilitate efficient bearing lubrication WQK standard spherical roller bearings are provided with three lubrication holes in the outer ring, usually in combination with an annular groove. Depending on the series and size, standard WQK spherical roller bearings are basically manufactured to four different designs,one of them is E design which consists of symmetrical rollers, two hardened window-type steel cages centred on the flangeless inner ring via a floating guide ring between the two rows of rollers.
