24092 CA.W33 STC spherical roller bearing

STC 24092 CA.W33 Spherical Roller Bearing – Heavy Duty Industrial Performance

The STC 24092 CA.W33 is a double-row, self-aligning rolling unit engineered for applications under extreme radial pressure. Thanks to its specific raceway geometry and barrel-shaped rollers, this bearing features a natural misalignment compensation capability. This model stands out with its CA internal design, featuring a solid two-piece brass cage that provides superior roller guidance, excellent thermal stability, and maximum resistance to heavy vibrations and dynamic shocks.

Application

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

Technical Specification

• Manufacturer: STC (Specialized Technical Components).
• Designation: 24092 CA.W33.
• Dimensions: 460 mm (ID) x 680 mm (OD) x 218 mm (Width).
• Internal Clearance: CN (Normal) – optimal for standard fits and stable operating temperatures.
• Cage (CA): Solid two-piece brass cage (inner ring guided).
• Lubrication (W33): Circumferential groove and three lubrication holes in the outer ring for efficient maintenance.

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: Automatic compensation for shaft deflection protects the bearing from harmful edge loading and premature wear.
• W33 System: Facilitates fresh lubricant delivery directly to the rolling zone, minimizing friction and aiding heat dissipation.
• Extreme Load Capacity: Double-row spherical design provides the highest resistance to radial pressures found in heavy industry.
• Open Design: Simplifies technical inspections and allows for free lubricant exchange in circulating systems.

Why Choose This Product

Opting for the STC 24092 CA.W33 bearing is a strategic decision for the uptime of your heaviest machinery. In 460 mm shaft applications, any unplanned failure results in staggering downtime and logistical costs. The combination of reinforced design, solid brass cage, and W33 lubrication makes this one of the most reliable solutions on the market for professionals prioritizing durability in the harshest environments.
