23060 CA.K.C3.W33 STC spherical roller bearing

STC 23060 CA.K.C3.W33 Spherical Roller Bearing – Heavy Duty

The STC 23060 CA.K.C3.W33 is a double-row rolling unit engineered for the most extreme industrial environments. Thanks to the barrel-shaped design of its rolling elements, this bearing possesses a natural self-aligning capability, allowing for faultless operation even under shaft deflections or housing misalignment. This model features a reinforced internal design (CA) with a solid brass cage, ensuring superior roller guidance and high resistance to vibrations and dynamic overloads.

Application

• Mining & Raw Materials: Vibrating screens, jaw crushers, and high-tonnage belt conveyors.
• Metallurgy: Rolling mills and auxiliary equipment in casting lines.
• Paper Industry: Heavy pressing and drying rollers subjected to high pressure and temperatures.
• Energy Sector: Main shaft bearings for wind turbines and generators.
• Civil Engineering: Slewing mechanisms and drives for TBMs and heavy-duty cranes.

Technical Specification

• Manufacturer: STC (Specialized Technical Components).
• Designation: 23060 CA.K.C3.W33.
• Dimensions: 300 mm (ID) x 460 mm (OD) x 118 mm (Width).
• Tapered Bore (K): 1:12 taper – designed for mounting with an adapter sleeve or directly onto a tapered shaft journal.
• Internal Clearance: C3 – greater than normal, ideal for high-temperature operations and heavy interference fits.
• Lubrication (W33): Annular groove and three lubrication holes in the outer ring for direct grease supply to the rollers.

Features and Benefits

• Solid Brass Cage (CA): Provides mechanical stability, better heat dissipation, and longer service life compared to steel cages.
• Misalignment Compensation: The self-aligning feature eliminates the risk of seizure due to shaft deflection.
• Thermal Resilience (C3): Increased clearance prevents bearing locking due to the thermal expansion of the shaft.
• Simplified Mounting: The tapered bore allows for precise adjustment of the operational clearance during installation.
• Maximum Radial Load Capacity: The double-row design accommodates massive forces while maintaining axial stability.

Why Choose This Product

By opting for the STC 23060 CA.K.C3.W33 bearing, you are investing in the process security of your critical machinery. In 300 mm shaft applications, any failure leads to staggering downtime costs. The combination of a brass cage, increased C3 clearance, and a tapered bore makes this one of the most versatile and durable solutions for heavy industry, ensuring smooth operation under the harshest conditions.
