SKF 51314 — Thrust ball bearing
SKF · Bearings & Power Transmission · Thrust Ball Bearings
SKF 51314 thrust ball bearing. Single-direction (51xxx) or double-direction (52xxx) thrust ball bearing designed to carry pure axial load at moderate speed. Cannot carry radial load. Series 511/512/513/514 covers the standard boundary plans. Manufactured to ISO 104 / ISO 492 Class Normal. Bore diameter d = 70 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 = 70 mm, outside diameter D = 125 mm, width B (or height H) = 40 mm.
