High Light NU208 cylindrical roller bearing 40x80x18mmsingle row cylindrical roller bearing floating designcylindrical roller bearing bidirectional axial slide
1. Product Overview

NU208 is single row cylindrical roller bearing. Outer ring equipped with double ribs while inner ring has no ribs. This floating design permits limited bidirectional axial sliding between shaft and housing to absorb thermal expansion. It features excellent heavy radial load capacity and suits continuous medium speed operation. Open structure supports regular re-lubriion maintenance. Widely used in industrial gearboxes, air compressors, conveyor drives, fans and general heavy-duty rotary equipment.

Formal quotation will be sent within 24 hours upon your inquiry.
