Super precision cylindrical roller bearings NNU49, non-locating bearing, double row, with tapered bore, taper 1:12, separable, with cage
Features
The 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 (polyetheretherketone). 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.
