SKF · Bearings & Power Transmission · Single-Row Tapered Roller Bearings
SKF BT1B639405/Q single-row tapered roller bearing. Single-row tapered roller bearing designed to take combined heavy radial and one-direction axial load. Cone (inner ring), cup (outer ring) and rollers converge at a common apex on the bearing axis. Two bearings are always mounted in opposition. Metric dimensions per ISO 355; imperial to ANSI/ABMA 19.1. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options.
