23160 CA.K.C3.W33 STC spherical roller bearing

STC 23160 CA.K.C3.W33 Spherical Roller Bearing – Heavy Duty Excellence

The STC 23160 CA.K.C3.W33 is a high-performance double-row rolling unit engineered to accommodate massive radial loads and significant axial forces. Thanks to the barrel-shaped rollers, this bearing features a natural self-aligning capability, ensuring faultless operation even under shaft deflections or housing misalignments. This model stands out with its CA internal design, featuring a solid brass cage that provides superior roller guidance, thermal stability, and maximum resistance to vibrations and dynamic shocks.

Application

• Mining Industry: Main bearings for heavy-duty crushers, vibrating screens, and conveyor drums.
• Metallurgy: Steel rolling mills, heavy casting machinery, and transport equipment in harsh environments.
• Paper Industry: Large-scale pressing and drying cylinders subjected to constant pressure.
• Energy Sector: Main shaft bearings for wind turbines and hydroelectric generators.
• Marine Engineering: Heavy-duty ship winches and slewing mechanisms for port cranes.

Technical Specification

• Manufacturer: STC (Specialized Technical Components).
• Designation: 23160 CA.K.C3.W33.
• Dimensions: 300 mm (ID) x 500 mm (OD) x 160 mm (Width).
• Tapered Bore (K): 1:12 taper – designed for mounting with an adapter sleeve or directly on a tapered shaft.
• Internal Clearance: C3 – increased radial clearance, ideal for high-temperature operations and heavy interference fits.
• Lubrication (W33): Annular groove and three lubrication holes in the outer ring for efficient relubrication.

Features and Benefits

• Solid Brass Cage (CA): Provides mechanical stability and longer service life compared to steel cages, especially under boundary lubrication.
• Self-Aligning Capability: Automatically compensates for misalignment, protecting the bearing from premature wear.
• C3 Clearance Advantage: Prevents bearing seizure caused by thermal expansion of the shaft during intense operation.
• Simplified Installation: The tapered bore allows for precise adjustment of operational clearance during seating.
• Extreme Load Rating: The double-row spherical design provides the highest resistance to radial pressures found in heavy industry.

Why Choose This Product

Opting for the STC 23160 CA.K.C3.W33 bearing is a strategic investment in the uptime of your heaviest machinery. In 300 mm shaft applications, any failure results in staggering downtime costs. The combination of a reinforced brass cage, increased C3 clearance, and W33 lubrication features makes this one of the most reliable solutions on the market for professionals prioritizing reliability.
