23076-E1A-K-MB1-C4 Double Row Spherical Roller Bearings, Symmetric 2 Outer Ribs With Rib Washer
The 23076-E1A-K-MB1-C4 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 23076-E1A-K-MB1-C4 bearing is a Double row spherical roller bearings, symmetric 2 outer ribs with rib washer with an inner diameter of 380 mm , an outer diameter of 560 mm, a width of 135 mm. GCr15, GCr15SiMn, SUJ2 rings, GCr15, SUJ2 rolling mlement. Its dynamic radial rated load is approximately 2899813 N, its static radial rated load is approximately 4999829 N. It uses C4 standard radial clearance, OPEN type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
23076-E1A-K-MB1-C4 bearings ( 380 mm x 560 mm x 135 mm) have the advantages of Small cross-section, high load-bearing capacity, self-aligning, and low friction, and are therefore widely used in the Gearbox, motor, space-constrained transmission components.

The 23076-E1A-K-MB1-C4 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.
