FTC 3309 Double Row Bearing

The FTC 3309 double row bearing is engineered for applications that demand high load capacity and durability. Its design makes it suitable for handling both radial and axial loads, providing stability and reliability in various industrial and automotive settings.

Technical Specifications:

• Type: Double Row Angular Contact Ball Bearing
• Inner Diameter (ID): 45 mm
• Outer Diameter (OD): 100 mm
• Width: 36 mm
• Weight: Approximately 1.6 kg (varies by manufacturer).

Design Features:

• Double Row Configuration: This bearing features two rows of balls, allowing it to effectively support substantial radial and axial loads from multiple directions. This configuration enhances load distribution and stability, making it ideal for high-stress applications.
• Angular Contact Design: Designed to accommodate combined loads, this bearing offers improved operational efficiency, especially in dynamic environments.

Construction and Materials:

• High-Quality Steel: Typically constructed from high-grade steel, providing excellent strength and wear resistance, thereby extending the service life of the bearing.
• Sealing Options: Often available with different sealing configurations (e.g., rubber seals like RS for complete sealing or metal shields like ZZ for partial protection), which help prevent contamination and retain lubrication.

Lubrication:

• Pre-Lubricated: Most FTC 3309 bearings are pre-lubricated with high-quality grease, minimizing friction and wear. Depending on the specific application, some designs may allow for re-greasing.

Performance Characteristics:

• Temperature Range: Designed to operate effectively within a wide temperature range, typically from -30°C to +120°C, although specific limits can vary based on the lubricant used.
• Noise and Vibration: The precision manufacturing processes minimize operational noise and vibrations, contributing to smoother performance in machinery.

Applications:

The FTC 3309 double row bearing is versatile and widely used in several applications, including:

• Automotive: Commonly used in wheel hubs, transmissions, and other drivetrain components where reliability is essential.
• Industrial Machinery: Found in conveyors, pumps, and heavy equipment that require robust load-bearing capabilities.
• Agricultural Equipment: Ideal for tractors and implements that operate under severe conditions, demanding high durability.

Key Benefits:

• Enhanced Load Capacity: The double row design allows for superior load distribution, enabling it to handle heavier loads than single-row alternatives.
• Stability and Rigidity: Provides excellent mechanical stability, crucial for applications experiencing fluctuating or high loads.
• Low Maintenance Requirements: Sealed or shielded designs reduce the frequency of maintenance, thus enhancing operational efficiency.
• Versatility: Suitable for a wide range of environments and applications, making it a reliable choice for various industries.

Conclusion:

The FTC 3309 double row bearing is a highly reliable option for applications that require robust performance and durability. Its design and construction enable effective load handling, making it suitable for diverse industrial and automotive applications.
