SKF 51130M 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 = 150 mm per ISO 15. Boundary plan per ISO 15 / ISO 355: bore d = 150 mm, outside diameter D = 190 mm, width B (or height H) = 31 mm.
