🔧 What is a DOUBLE ROW ANGULAR CONTACT BEARING?

A Double Row Angular Contact Bearing is a type of ball bearing designed to support both radial loads and axial loads in two directions. It consists of two rows of balls in a single unit, functioning similarly to a matched pair of single-row angular contact bearings—while saving space and simplifying installation.

⚙️ Working Principle

• The bearing features a contact angle between the balls and raceways
• This angle allows it to handle axial (thrust) loads in addition to radial loads
• With two rows, it can support axial forces in both directions

➡️ Ideal for applications with combined loads and bidirectional thrust

✅ Key Features

• Supports radial + axial loads (both directions)
• Higher rigidity and load capacity than single-row bearings
• Space-saving design (replaces two single-row bearings)
• Simplified mounting and alignment
• High precision and stability

📊 Main Components

• Two rows of steel balls
• Angular contact raceways
• Cage (ball separator)
• Optional seals or shields (e.g., 2RS, ZZ types)

⚙️ Applications

• Electric motors
• Pumps and compressors
• Gearboxes and transmission systems
• Industrial machinery
• Automotive wheel hubs
• Machine tools
