BS2-2316-2RSK/VT143 Spherical Roller Bearings, Stamping Steel Cage, Tapered Bore
The BS2-2316-2RSK/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 BS2-2316-2RSK/VT143 bearing is a Sealed spherical roller bearings with an inner diameter of 80 mm , an outer diameter of 170 mm, a width of 67 mm. High-carbon chromium steel rings, High-carbon chromium steel rolling mlement. Its dynamic radial rated load is approximately 507925 N, its static radial rated load is approximately 531820 N. It uses CN standard radial clearance, 2RS = Contact seal, NBR, on both sides type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
BS2-2316-2RSK/VT143 bearings ( 80 mm x 170 mm x 67 mm) have the advantages of Self-aligning, high load-bearing capacity, and impact resistant, and are therefore widely used in the Mining machinery, metallurgical equipment, papermaking machinery, vibrating screens, wind turbines, and large industrial gearboxes.

The BS2-2316-2RSK/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.
