Detailed description

Double row spherical roller bearings - 3844 220X320X76mm

Spherical roller bearings are intended for accommodation of radial load, but they simultaneously can accommodate axial load, acting in both directions and not exceeding 25% of unused permissible

value of radial load.

They are self-aligning bearings and they are able to compensate considerable misalignment, caused by shaft deflection under load and technical errors during the machining of seatings, or unit assembling. Bearings performance is kept when misalignment of the inner ring axes relative to the outer ring axes is about two degrees. They fix shaft in both sides of axial direction within existing axial clearances.
