Advanced Product Solutions
While contending with high heat, heavy loads, low speed and water exposure, the bearings used in continuous casting machinery must operate with reliability to ensure that yield, productivity and cost-efficiency is maximized. NSK’s new NUB series cylindrical roller bearings are designed to be particularly effective for the free end of strand guide rolls, accommodating roll shaft bending and expansion while running with reduced sliding friction and wear for a longer, reliable operating life.
|Extended operating life – as much as 3 times that of alternative solutions
|Reduced internal differential sliding friction and wear
|Accommodates roll shaft bending / misalignment
|Smoothly absorbs roll expansion resulting from high operating temperatures
|Easy installation with non-separable design
|Single row, full complement cylindrical roller bearing
|Extremely high capacity internal design parameters, with optimal size and number of rollers
|Optimized roller crowning reduces internal sliding friction and wear while absorbing roll bending
|Non-separable, with outer ring ribs and inner ring retaining rings for ease of installation
|Rib-free inner ring permits axial displacement in both directions
|Relative movement characteristics of inner and outer raceways smoothly absorb roll expansion
|Dimensionally interchangeable with conventional bearing types
|Radial internal clearance C4 is standard
