23084 CA.K.C3.W33 STC spherical roller bearing

STC 23084 CA.K.C3.W33 Spherical Roller Bearing – Heavy Duty

The STC 23084 CA.K.C3.W33 is a double-row rolling unit engineered for extreme load-carrying capacity in strategic industrial applications. Thanks to the barrel-shaped rollers, this bearing features a natural self-aligning capability, ensuring faultless operation even under significant shaft deflections or housing misalignments. This model stands out with its CA internal design, featuring a solid two-piece brass cage that provides precise roller guidance, thermal stability, and maximum resistance to vibrations and dynamic shocks.

Application

• Mining Industry: Main bearings for heavy-duty crushers, vibrating screens, and large conveyor drive drums.
• Metallurgy: Steel rolling mills, heavy casting machinery, and transport equipment in high-temperature zones.
• Paper Industry: Large-scale pressing and drying cylinders subjected to constant pressure.
• Energy Sector: Main shaft bearings for offshore 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: 23084 CA.K.C3.W33.
• Dimensions: 420 mm (ID) x 620 mm (OD) x 150 mm (Width).
• Tapered Bore (K): 1:12 taper – designed for mounting with an adapter sleeve or directly onto a tapered shaft.
• Internal Clearance: C3 – increased radial clearance to prevent seizure during shaft thermal expansion.
• Lubrication (W33): Circumferential groove and three holes in the outer ring for optimal grease distribution.

Features and Benefits

• Solid Brass Cage (CA): Ensures 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 edge loading and premature wear.
• C3 Clearance Advantage: Ideal for high thermal dynamics, ensuring smooth operation across a wide temperature range.
• Efficient Installation: Tapered bore allows for precise adjustment of operational clearance using lock nuts or hydraulic tools.
• Extreme Radial Load Capacity: Double-row spherical design facilitates handling the highest forces found in heavy industry.

Why Choose This Product

Opting for the STC 23084 CA.K.C3.W33 bearing is an investment in the uptime of your heavy infrastructure. In 420 mm shaft applications, any failure results in staggering downtime costs and complex replacement logistics. 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 uncompromising durability.
