Double Row Ball Bearings: The Workhorses of Industrial Machinery
What Are Double Row Ball Bearings?
Double row ball bearings are a type of rolling-element bearing that features two rows of balls in a single raceway. This design provides increased load capacity and rigidity compared to single-row ball bearings.
Benefits of Double Row Ball Bearings
-
High load capacity: The two rows of balls distribute the load more evenly, allowing double row ball bearings to withstand higher radial and axial loads.
-
Increased rigidity: The close spacing of the balls in the two rows provides greater stiffness, reducing deflection and vibration.
-
Low friction: Double row ball bearings roll smoothly, resulting in low friction and energy consumption.
-
Long service life: Proper lubrication and maintenance ensure a long service life for double row ball bearings.
Applications of Double Row Ball Bearings
Double row ball bearings are widely used in various industrial applications, including:
- Power transmission machinery
- Electrical motors
- Pumps
- Gearboxes
- Conveyors
- Machine tools
Types of Double Row Ball Bearings
Double row ball bearings are available in various types, including:
| Type |
Description |
|
Open type: These bearings have no seals or shields and are open to the environment. |
|
|
Shielded type: These bearings have metal shields on both sides to protect from dust and moisture. |
|
|
Sealed type: These bearings have rubber seals on both sides to provide better protection against water and contaminants. |
|
|
Flanged type: These bearings have a flange on one side, allowing for easier mounting. |
