SKF · Bearings & Power Transmission · Needle Roller Bearing Components
SKF IR45X55X22 needle roller bearing component (inner ring / cage assembly / individual roller). Component supplied separately from the full needle bearing — replacement inner ring (IR series), needle roller and cage assembly (KZK / KBK), stand-alone needle roller, or drawn-cup outer sleeve. Used for shaft-diameter matching or replacement on integrated assemblies. Dimensioned to ISO 3245 / DIN 617. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options.
