The 241/670-2CS5K30/C3HGEA8 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 241/670-2CS5K30/C3HGEA8 bearing is a Sealed spherical roller bearings with an inner diameter of 670 mm , an outer diameter of 1090 mm, a width of 412 mm. High-carbon chromium steel rings, High-carbon chromium steel rolling mlement. Its dynamic radial rated load is approximately 16401896 N, its static radial rated load is approximately 28979955 N. It uses C3H standard radial clearance, 2CS5 = Contact seal, HNBR, on both sides type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
241/670-2CS5K30/C3HGEA8 bearings ( 670 mm x 1090 mm x 412 mm) have the advantages of High load-bearing capacity, impact resistant, self-aligning, and easy to install, and are therefore widely used in the Wind turbine main shaft, large ship main shaft, giant construction machinery.

The 241/670-2CS5K30/C3HGEA8 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.
