SKF 21309 EK Spherical Roller Bearing
Spherical roller bearings put two rows of barrel-shaped rollers inside an outer ring whose raceway is a single spherical surface, so the inner ring and roller set can swivel freely within it. That geometry makes the bearing self-aligning: it shrugs off shaft deflection and housing misalignment on the order of one to two degrees while carrying very heavy radial loads plus axial load in either direction. The dimension series (21300, 22200, 22300, 23000, 23100, 24000) scale from slim sections to wide, extremely heavy-duty ones. Design letters describe the internal build: E versions use an optimised, higher-capacity roller set, CC versions run window-type steel cages with a floating guide ring, and CA versions carry machined brass cages for vibration-prone duty. A K suffix means a tapered bore for sleeve mounting, and /W33 adds a lubrication groove and holes in the outer ring. Typical designations include 22212 E, 23120 CC/W33 and 22317 EK, specified wherever loads are brutal and alignment cannot be guaranteed. In Saudi industry these are the workhorses of cement plant crushers, vibrating screens, conveyor pulleys, fans and steel mill equipment, and stocking them locally keeps Jubail, Yanbu and Riyadh plants out of extended downtime. Key specifications for 21309 EK: d 45 mm Bore diameter; B 25 mm Width; Bore diameter 45 mm; Outside diameter 100 mm; Width 25 mm; Basic dynamic load rating 129 kN. 21309 EK is available from Razz Middle East in Jeddah, Saudi Arabia, with GCC-wide delivery and a 4-hour RFQ response.
