FTC 3311 Double Row Bearing

FTC 3311 Double Row Bearing: Detailed Description

The FTC 3311 double row bearing is engineered for applications that demand high load capacity, stability, and durability. Its robust design allows it to effectively manage both radial and axial loads, making it a versatile choice for various industrial and automotive settings.

Technical Specifications:

• Type: Double Row Angular Contact Ball Bearing
• Inner Diameter (ID): 55 mm
• Outer Diameter (OD): 120 mm
• Width: 43 mm
• Weight: Approximately 2.5 kg (may vary by manufacturer).

Design Features:

• Double Row Configuration: The bearing features two rows of balls, allowing it to support significant radial and axial loads from multiple directions. This configuration enhances load distribution and overall stability, making it suitable for high-stress applications.
• Angular Contact Design: Designed to accommodate combined loads, which improves operational efficiency and performance in dynamic environments.

Construction and Materials:

• High-Quality Steel: Typically made from premium-grade steel, offering excellent strength and wear resistance, which contributes to a longer service life.
• Sealing Options: Available with various sealing configurations (e.g., rubber seals like RS for full sealing or metal shields like ZZ for partial protection), which help prevent contamination and retain lubrication.

Lubrication:

• Pre-Lubricated: Most FTC 3311 bearings are pre-lubricated with high-quality grease, minimizing friction and wear. Some designs may allow for re-greasing, depending on application requirements.

Performance Characteristics:

• Temperature Range: Designed to operate effectively across a wide temperature range, typically from -30°C to +120°C, although specific limits may vary based on the lubricant used.
