23218-E1A-M-H151B Double Row Spherical Roller Bearings, Main Dimensions To DIN 635-2
The 23218-E1A-M-H151B Double-row spherical roller bearings are suitable for heavy-load, impact, and eccentric conditions. Classic applications include vibrating screen exciters, crushers, fans, paper machine press rolls, mining conveyor equipment, and marine propulsion shafts.
The 23218-E1A-M-H151B bearing is a Double row spherical roller bearings, main dimensions to DIN 635-2 with an inner diameter of 90 mm , an outer diameter of 160 mm, a width of 52.4 mm. GCr15, GCr15SiMn, SUJ2 rings, GCr15, SUJ2 rolling mlement. Its dynamic radial rated load is approximately 444808 N, its static radial rated load is approximately 519830 N. It uses CN standard radial clearance, OPEN type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
23218-E1A-M-H151B bearings have the advantages of Self-aligning, extremely high load-bearing capacity, thinnest cross-section, low friction, suitable for confined spaces, and are therefore widely used in the Large crushers, mills, and rotary kilns.

The 23218-E1A-M-H151B Double-row spherical roller bearings mainly consist of an inner ring, an outer ring, two rows of spherical rollers, a cage, and seals. The outer ring raceway has a spherical structure, while the inner ring has a double-row raceway. The rollers and raceways are logarithmically curved. The cage is typically made of stamped steel or machined brass.
Double-row spherical roller bearings possess excellent self-aligning properties, compensating for shaft deflection, installation errors, and misalignment. They can simultaneously withstand radial loads and bidirectional axial loads, exhibiting extremely high load-bearing capacity and strong impact resistance. Furthermore, the internal clearance can be optimized for vibration conditions, effectively reducing frictional temperature rise.
