23130 2-2CS5K/VT143 Bore 150 Mm, Stamped Steel Cage, Sealed Spherical Roller Bearings
The 23130 2-2CS5K/VT143 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 23130 2-2CS5K/VT143 bearing is a Sealed spherical roller bearings with an inner diameter of 150 mm , an outer diameter of 250 mm, a width of 80 mm. GCr15SiMn rings, GCr15SiMn rolling mlement. It uses Normal standard radial clearance, 2CS5 = Contact seal, HNBR, on both sides type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
23130 2-2CS5K/VT143 bearings ( 150 mm x 250 mm x 80 mm) have the advantages of Self-aligning, high load-bearing capacity, impact resistant, and adaptable to heavy loads, and are therefore widely used in the Gearboxes, drive shafts, conveying equipment, general machinery.

The 23130 2-2CS5K/VT143 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.
