The 2309-M RICH is a high-capacity self-aligning ball bearing engineered for heavy industrial environments where shaft deflection or misalignment is a critical factor. Featuring dimensions of 45 x 100 x 36 mm, this bearing is part of the robust 2300 series, which offers a larger cross-section and higher load-carrying capacity than standard series self-aligning bearings. Its internal design consists of two rows of balls that run on a common sphered raceway in the outer ring, allowing the inner ring and balls to tilt freely to compensate for angular misalignment.

This premium variant is equipped with a machined brass cage (M), guided by the rolling elements. Brass cages are significantly more durable than standard steel or polyamide cages, providing superior performance in applications involving high vibration, heavy shock loads, or extreme operating temperatures. The open design facilitates easy lubrication through the machine's housing system, ensuring consistent performance in high-speed industrial drives.

The 2309-M RICH is manufactured to provide maximum structural stiffness and operational reliability, making it an ideal choice for heavy machinery where precision alignment is difficult to maintain.

Key Performance Advantages:

• Superior Misalignment Compensation: Insensitive to angular misalignment of the shaft relative to the housing.
• Machined Brass Cage: Enhances durability and heat resistance, ideal for heavy-duty and vibrating environments.
• High Radial Load Capacity: The 2300 series design supports significantly higher forces than standard series.
• Reduced Frictional Heat: Precision-ground components minimize energy loss and extend lubricant life.
• RICH Heavy-Duty Standard: Engineered for long-term service in demanding industrial power transmissions.

Typical Applications:

• Industrial fans, blowers, and centrifugal separators.
• Heavy-duty agricultural machinery and harvesting equipment.
• Textile and paper processing machinery.
• General mechanical systems with long shafts prone to deflection.
