DOUBLE ROW ANGULAR CONTACT BEARING
🔧 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
