🔧 RADIAL / DEEP GROOVE BALL BEARING – ROUND BORE

A Radial (Deep Groove) Ball Bearing – Round Bore is the most widely used type of rolling bearing. It is designed primarily to support radial loads, while also accommodating moderate axial loads in both directions. The round bore (cylindrical inner diameter) allows direct mounting onto standard shafts for simple, reliable installation.

⚙️ Working Principle

• Steel balls roll between deep raceway grooves on inner and outer rings
• The deep groove design ensures smooth rotation and low friction
• Supports radial loads and light-to-moderate axial loads (both directions)

➡️ Ideal for high-speed and general-purpose applications

✅ Key Features

• Low friction & high-speed capability
• Handles radial + moderate axial loads
• Simple design, easy installation (round bore)
• Low maintenance & long service life
• Available in open, shielded (ZZ), or sealed (2RS) versions

📊 Main Components

• Inner ring (round bore / cylindrical bore)
• Outer ring
• Steel balls (rolling elements)
• Cage (separator)
• Optional seals/shields (2RS / ZZ)

⚙️ Applications

• Electric motors and fans
• Pumps and compressors
• Gearboxes
• Household appliances
• Automotive components
• General industrial machinery
