Deep Groove Ball Bearings

At Kriloha Ltd., we understand that “Universal-Reliability” is the cornerstone of industrial productivity. Our Deep Groove Ball Bearings are our engineered answer for “Friction-Optimization” and “Multi-Directional-Support”. As a leading provider of industrial components, Kriloha has curated a ball bearing series that balances mechanical invincibility with the operational agility required for high-speed modern equipment.

The engineering of our deep groove series is based on Precision-Geometry. By utilizing raceways that are super-finished to sub-micron levels, we ensure that the balls travel with minimal resistance, significantly extending the service life of the lubricant and the bearing. At Kriloha, we verify that our bearings meet P0 or P6 precision standards as a minimum, utilizing high-carbon chromium steel that has been through-hardened for maximum fatigue resistance. This creates a “Quiet-Resilient” support system that remains stable under a wide variety of load conditions.

Manufacturing these bearings involves strict Dynamic-Balance Verification. We ensure that each component provides the vibration-free performance required for sensitive electronic and medical equipment. Whether you are maintaining a high-efficiency HVAC system or a high-speed production line, Kriloha Deep Groove Ball Bearings provide the mechanical durability your facility demands. By choosing Kriloha Ltd., you are investing in a “Standard-Setting” technology that secures your most important rotating assets.

Handheld Power Tools: Providing smooth shaft support for drills, grinders, and sanders.

Frequently Asked Questions

1. Why is it called a “Deep Groove” bearing?
The name refers to the raceway grooves in both the inner and outer rings, which have arcs slightly larger than the radius of the balls. This allows the balls to handle axial loads better than shallow-groove designs.
2. What is the difference between a Shield (ZZ) and a Seal (2RS)?
A shield (ZZ) is a non-contact metal plate that protects against larger debris; a seal (2RS) is a contact rubber part that provides better protection against dust and moisture but may slightly increase friction.
3. Can these bearings handle heavy axial thrust?
While they can handle axial loads in both directions, they are primarily radial bearings. For very high axial loads, an angular contact or thrust-specific bearing may be more appropriate.
4. Are these bearings pre-lubricated?
Sealed and shielded versions from Kriloha are typically “greased for life,” meaning they are pre-filled with high-quality lubricant and require no further maintenance.
5. How do I choose the correct internal clearance (e.g., C3)?
Standard clearance is suitable for most tasks. C3 (greater than normal) is recommended for applications where high heat may cause the inner ring to expand more than the outer ring.
