Spherical roller bearings — models 23120, 23121, 23122, 23124, 23126 and 23128 CA W33 Key benefits — why you need these bearings and how they solve problems High radial load capacity: supports heavy loads typical in industrial and material‑handling equipment. Self-aligning design: compensates for shaft misalignment and reduces stress on adjacent components, lowering downtime and maintenance. Durable in harsh environments: engineered for long service life under heavy loads, shock, and contamination common in demanding applications. Predictable performance across temperatures and speeds: maintains reliable operation across a wide range of operating conditions. Clear model differentiation and fit options: CA and W33 variants let you control internal clearance and mounting fit for specific assemblies. Important attributes — function, compatibility and fit Models available: 23120, 23121, 23122, 23124, 23126, 23128 CA W33 — a range that provides flexible replacement options for existing equipment. 23128 variant: identified by color code 23128w33 and uses the CA size for a precise fit. Compatibility: designed to work with standard housings and shaft sizes, simplifying retrofits and inventory management. Function: spherical rollers with a self‑aligning outer ring to accommodate slight shaft deviations while carrying heavy radial loads. Performance: stable operation at varying speeds and temperatures with predictable life characteristics under load. Practical applications — where these bearings deliver value Mining conveyors and crushers: absorbs shaft misalignment and supports heavy radial loads in abrasive, high‑impact conditions. Rolling mills and presses: resists deformation and wear under continuous heavy loading and shock. Gearboxes and heavy machinery in material handling: provides reliable bearing life and controlled internal clearance for assemblies that require precise fit and predictable performance. How to choose Match the model to your existing housing and shaft dimensions, load requirements, and allowable alignment tolerance. Select the CA or W33 variant when you need controlled internal clearance or specific mounting characteristics. For assemblies requiring a precise CA fit with the W33 clearance option, use the 23128 CA W33 (color code 23128w33). If you need help selecting the correct model for load, speed, and alignment conditions, provide your shaft/housing dimensions and operating parameters to confirm fit and expected life.
