Technical Datasheet: 23122-2CS5/VT143 SKF Sealed Spherical Roller Bearing

1. Dimensional Specifications (ISO 15 Rolling Bearing Standard)
SKF 23122-2CS5/VT143 double-row spherical roller bearing: Bore d=110 mm, outer diameter D=180 mm, overall width B=69 mm, fillet radius r=2 mm. Adopts standard P0 industrial tolerance grade; bore dimensional tolerance 0/-0.022 mm, outer ring tolerance 0/-0.026 mm. Equipped with dual-sided CS5 heavy-duty contact rubber seals for strong resistance to slurry, dust and moisture. VT143 heat stabilization treatment allows stable size retention under sustained high heat, with built-in self-aligning capacity of ±1.5° to compensate shaft mounting misalignment.
2. Material Composition & Mechanical Performance
Inner ring, outer ring and spherical rollers: Vacuum refined 100Cr6 bearing steel, finished to HRC 60–64, featuring outstanding contact fatigue resistance and abrasive wear resistance. Machined solid brass cage CuZn40Pb2 separates rollers uniformly, resisting high temperature and continuous vibration deformation. CS5 sealing lip adopts durable FKM fluororubber, superior heat resistance and compatibility with high-temperature complex greases. VT143 special tempering eliminates internal residual stress to avoid thermal creep under long-duration high-load operation.
3. Core Manufacturing Processes
1. Closed hot forging optimizes metal grain distribution and eliminates internal casting defects.
2. CNC hard turning ensures consistent blank dimensional precision.
3. Custom VT143 stabilization heat treatment combined with standard quenching and low-temperature tempering.
4. Precision raceway and roller grinding with surface roughness Ra ≤0.02 μm.
5. Oscillating superfinishing reduces friction coefficient and running noise. All processes comply with SKF global manufacturing standards and ISO 3290.
4. Service Life Performance
Dynamic radial load Cr=465 kN, static load rating C0r=582 kN, calculated per ISO 281:2019. Under standard operating conditions (radial load ≤0.3Cr, working temperature -20°C to 155°C, intact CS5 sealing and sufficient lubrication), nominal L10 service life reaches over 36,000 working hours. Primary life-limiting factors include severe shaft misalignment, frequent shock overload, seal failure leading to particle contamination, and grease carbonization under overheating.
5. Industrial Application Fields
SKF 23122-2CS5/VT143 sealed self-aligning spherical roller bearing targets heavy-load equipment operating in dusty, humid and high-temperature harsh environments. Key industries: mining crushing equipment, cement production rollers, metallurgical continuous casting lines, heavy construction machinery, port bulk conveyors and large agricultural processing equipment. Its self-aligning structure offsets installation deflection, while CS5 heavy seals greatly extend lubrication intervals in polluted working sites.
6. Routine Maintenance Standards
Lubrication cycle: Every 90 working hours for dusty high-temperature sites; 280 hours for clean moderate-temperature workshops. Recommended lubricant: high-temperature EP3 lithium complex grease, filling 30%–40% of bearing internal cavity. Monthly compressed air cleaning to remove surface slurry and dust; regular inspections cover seal aging, roller spalling and grease degradation. Persistent abnormal vibration or temperature rise over 40°C above ambient requires immediate disassembly inspection.
7. Installation Guidelines
Pre-installation: Fully clean shaft and housing seats, remove burrs and metal debris. Installation: Apply thermal fitting for inner ring assembly; avoid direct hammer impact on outer ring and seal components. Shaft coaxiality error controlled below 0.03 mm; lock nut tightening torque 290–330 N·m. Post-installation 30-minute no-load test to monitor running temperature and vibration. Wear heat-resistant gloves during hot mounting to prevent scalding and scratch damage to bearing sealing surfaces.
