Description

Carries axial loads in a single direction while allowing free radial displacement of the shaft, transferring force through cylindrical rollers guided in a machined brass cage (M). Bore diameter is 360.0 mm, outside diameter 500.0 mm, height 110.0 mm, with a net mass of 71.13 kg. Limiting speed is rated at 650.0 1/min, reference speed at 197.0 1/min. Being a single-row axial cylindrical roller bearing, it must be paired with separate radial location elements, as it does not constrain radial movement itself. The machined cage construction supports stable roller guidance at the given speed ratings, and the bearing requires precise axial alignment during mounting to ensure even load distribution across the roller set. Lubrication should be selected to match the reference speed value, keeping film formation stable under the rated axial load path.
