23184 CA.K.C3.W33 STC spherical roller bearing

STC 23184 CA.K.C3.W33 Spherical Roller Bearing – Heavy Duty Reliability

The STC 23184 CA.K.C3.W33 is a double-row, self-aligning rolling unit engineered to handle extreme radial loads and significant axial forces in both directions. Thanks to its barrel-shaped rollers, this model automatically compensates for shaft-to-housing misalignment, preventing harmful edge stresses. The CA execution features a solid two-piece brass cage, ensuring superior roller guidance and high resistance to vibrations and elevated temperatures.

Application

• Mining & Quarrying: Main bearings for heavy-duty crushers, vibrating screens, and conveyor belt drums.
• Metallurgy: Steel rolling mills, casting machinery, and heavy industrial transport systems.
• Energy Sector: Low-speed shafts for hydroelectric turbines and main gearboxes in wind power plants.
• Paper Industry: Large-scale pressing and drying cylinders subjected to constant pressure.
• Heavy Construction: Slewing mechanisms in port cranes and TBMs (Tunnel Boring Machines).

Technical Specification

• Manufacturer: STC (Specialized Technical Components).
• Designation: 23184 CA.K.C3.W33.
• Dimensions: 420 mm (ID) x 700 mm (OD) x 224 mm (Width).
• Tapered Bore (K): 1:12 taper – ideal for mounting with an adapter sleeve or on a tapered journal.
• Internal Clearance: C3 – increased radial clearance to prevent seizure during thermal expansion.
• Lubrication (W33): Circumferential groove and three lubrication holes in the outer ring for easy maintenance.

Features and Benefits

• Solid Brass Cage (CA): Provides higher mechanical rigidity and longer service life than steel cages, especially under boundary lubrication.
• Self-Alignment: Accommodates shaft deflections, drastically reducing the risk of premature failure.
• C3 Clearance Advantage: Offers a safety margin in high-heat industrial applications.
• W33 System: Facilitates direct lubricant delivery to the rolling zone, reducing friction.
• STC Durability: High-purity bearing steel ensures exceptional resistance to material fatigue.

Why Choose This Product

By investing in the STC 23184 CA.K.C3.W33 bearing, you ensure the operational uptime of your heaviest machinery. With a 420 mm bore, bearing replacement is a major logistical task – choosing a proven design with a brass cage and tapered bore simplifies precision mounting and guarantees years of maintenance-free service in harsh environments.
