  • What to know when setting two-row tapered roller

    The double row tapered roller bearing unit in an ‘O’ arrangement, with grease lubrication and seals, is supplied pre-assembled. The inner rings are flange-mounted to the rotor, while the outer ring is flange-mounted to the nacelle of the wind turbine. The bearing clearance is preset, which significantly reduces logistics and mounting costs.
