Product Overview: The 23121 Spherical Roller Bearing
The 23121 Spherical Roller Bearing is a high-capacity component engineered for the most demanding industrial environments. With dimensions of 105x170x41mm, this bearing is a key part of our 23100 Series within the broader Spherical Roller Bearings collection. Its design features two rows of symmetrical barrel-shaped rollers and a common sphered outer ring raceway, which allows it to accommodate significant shaft deflection and misalignment between the shaft and housing. This self-aligning capability makes it indispensable in heavy-duty machinery where maintaining perfect alignment is challenging.
Built to handle severe radial loads and substantial axial loads in both directions, the 23121 bearing provides exceptional reliability and a long service life. As a trusted supplier of industrial parts, we ensure our bearings meet rigorous quality standards, offering robust performance in applications across mining, construction, and manufacturing sectors. Explore our comprehensive range of spherical roller bearings to find the ideal solution for your heavy-load requirements.
Features of the 23121 Bearing
- Excellent Misalignment Compensation: The spherical outer raceway allows for angular self-alignment, accommodating shaft deflection and mounting errors.
- High Radial and Axial Load Capacity: The double-row roller design is optimized to support very heavy radial loads and significant axial loads in both directions.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for superior strength, durability, and wear resistance.
- Symmetrical Barrel Rollers: Ensures optimal load distribution along the roller length, reducing stress peaks and extending operational life.
- Low-Friction Design: Precision engineering minimizes rotational friction, which reduces operating temperature and allows for higher speed capabilities.
- Cylindrical Bore: Designed for a standard straight shaft mounting, providing a secure and reliable fit.
Common Applications
- Mining and Construction: Widely used in crushers, vibrating screens, conveyor systems, and heavy earth-moving equipment.
- Pulp and Paper Mills: Essential for rollers in paper machines, calendars, and presses where heavy loads and misalignment are common.
- Steel Manufacturing: Deployed in continuous casters, rolling mills, and other high-temperature, high-load machinery.
- Industrial Gearboxes: Provides reliable support for gears and shafts in large-scale industrial transmissions and speed reducers.
- Wind Turbines: Used in main shafts and gearboxes to handle the immense and fluctuating loads generated by wind power.
- Marine and Offshore: Suitable for propulsion systems, cranes, and winches that operate under harsh conditions.
- Large Fans and Blowers: Supports rotors in industrial ventilation systems, accommodating potential imbalances and shaft deflections.
Benefits of Using the 23121 Bearing
