The 2313.M RICH is a premium-grade self-aligning ball bearing designed for high-capacity industrial applications where shaft misalignment or deflection is a significant operational challenge. With its substantial dimensions of 65 x 140 x 48 mm, this bearing belongs to the heavy 2300 series, offering a larger cross-section and higher load ratings compared to standard series bearings.

The internal design features two rows of balls and a common sphered raceway in the outer ring, which allows the bearing to be completely insensitive to angular misalignment of the shaft relative to the housing. This model is equipped with a machined brass cage (M), which is guided by the rolling elements. The brass construction provides exceptional durability and heat resistance, making it particularly suitable for applications involving high vibrations, shock loads, or aggressive operating conditions where steel or plastic cages might fail.

The open design of the 2313.M RICH allows for efficient lubrication within the mechanical assembly. Engineered to provide maximum structural stiffness, it ensures long-term reliability in heavy-duty powertrain and manufacturing systems.

Key Performance Advantages:

• Superior Misalignment Compensation: Dynamically adjusts to shaft deflections without increasing friction or stress.
• Robust Machined Brass Cage: Offers superior strength and stability in high-temperature and high-vibration environments.
• Extra-Heavy Load Capacity: The 2300 series profile provides enhanced radial support for industrial machinery.
• Low Operational Friction: Precision-ground raceways ensure smooth rotation and reduced energy loss.
• RICH Industrial Durability: Manufactured with high-grade steel to resist wear and extend maintenance intervals.

Typical Applications:

• Heavy-duty industrial fans, blowers, and air-handling units.
• Agricultural machinery and large-scale harvesting equipment.
• Textile and paper processing machinery prone to shaft misalignment.
• General industrial drive systems with long shafts or flexible support structures.
