SKF 7309BECBY — Angular contact ball bearing
SKF · Bearings & Power Transmission · Angular Contact Ball Bearings
SKF 7309BECBY angular contact ball bearing. Single-row angular contact ball bearing configured to take combined radial and one-direction axial load. Contact angle 15°, 25°, 30° or 40° per suffix (BE / BEP / BECBP execution). Two bearings are commonly mounted in an opposing pair (back-to-back, face-to-face or tandem) so the pair carries axial load in both directions and takes moment load. Manufactured to ISO 492 Class Normal. Bore diameter d = 45 mm per ISO 15. Designation follows the ISO 15 / DIN 623 alphanumeric convention where the numeric block encodes the dimension series and bore code; suffixes after the numeric block declare cage, closure, precision, clearance and lubricant execution. Genuine SKF supply carries the SKF logo etch on the outer ring face and hologram-authenticated packaging. Boundary plan per ISO 15 / ISO 355: bore d = 45 mm, outside diameter D = 100 mm, width B (or height H) = 25 mm.
