Description
FAG Double Row Super Precision Cylindrical Roller Bearings: FAG super precision cylindrical roller bearings comprise solid outer rings, solid inner rings with a tapered bore (taper 1:12) and cylindrical roller and cage assemblies with cages made from polyamide, brass or PEEK (polyether ether ketone). The outer ring is removable and can thus be mounted separately from the rest of the bearing package. The inner ring is only removable in the case of series NNU49. The single and double row bearings are used when very high precision under very high radial load is required. Typical areas of application include machine tools and printing machinery. The bearings facilitate bearing arrangements with very high precision, high radial rigidity and very high load-carrying capacity. In machine tool building, they provide radial support for the main spindle.
Benefits: Low noise levels, higher basic load ratings, less lubricant strain.
