SKF 51122 Thrust Ball Bearing

Thrust ball bearings are built for one job: carrying axial load along the shaft axis. The single-direction SKF 51100, 51200 and 51300 series use a separable three-piece construction — a shaft washer, a housing washer and a ball-and-cage assembly between them — which makes mounting simple because each piece drops into place independently. The grooved washers seat the balls fully, giving good axial capacity in one direction, but the design accepts no radial load and must always be kept under a minimum axial load at speed, otherwise centrifugal force lets the balls skid instead of roll. Bore sizing follows the standard metric rule: for codes 04 and above, the last two digits times five give the bore, so a 51108 fits a 40 mm shaft and a 51210 a 50 mm shaft, with the third digit (1, 2 or 3) signalling progressively heavier cross-sections. Engineers pick them for moderate-speed vertical shafts and screw-drive arrangements where a defined thrust path matters. Saudi buyers order these mainly for vertical turbine pumps at desalination and water-injection stations, valve actuators and gate-valve stems across Aramco facilities, and crane hooks and screw jacks in Jubail and Yanbu fabrication yards, where the separable washers speed up field replacement. Key specifications for 51122: d 110 mm Bore diameter; Bore diameter 110 mm; Outside diameter 145 mm; Basic dynamic load rating 83.2 kN; Basic static load rating 285 kN; Limiting speed 3 200 r/min. 51122 is available from Razz Middle East in Jeddah, Saudi Arabia, with GCC-wide delivery and a 4-hour RFQ response.
