Split Cylindrical
Roller Bearing Units

NSK Split Cylindrical Roller Bearing Units are ideally designed to simplify bearing replacement in segmented drive rolls of continuous casting lines, eliminating the complexity of dismantling the roll and thereby reducing total maintenance downtime. But not at the expense of performance. Optimized roller length and profile delivers high capacity and reduced wear. And an advanced seal arrangement prevents water and particle ingress and grease leakage. It also improves performance when employing oil-air lubrication. Inside and out, NSK Split Cylindrical Roller Bearing Units are engineered to deliver utmost capacity and efficiency for a long bearing life.
