Precision Bright Steel Bars for Bearings
In the demanding world of bearings, wear mechanisms can lead to premature failure. Our cold drawn, turned, and centreless ground bright steel bars provide the surface quality and dimensions needed for reliable performance.
The wear problem
Bearing components often face sliding abrasion and impact wear, leading to surface degradation and dimensional inaccuracies. The initial failure typically occurs at the bearing surfaces, where consistency and finish are critical for longevity.
Recommended plate by component
| Component | Grade | Thickness | Why |
|---|---|---|---|
| Bearing inner race | 535A99 (62-66 HRC) | 20-50 mm | Superior hardness ensures extended wear life. |
| Bearing outer race | 100Cr6 (58-64 HRC) | 30-75 mm | Excellent wear resistance against fatigue failure. |
| Bearing shaft | 709M40 (28-32 HRC) | 15-40 mm | Balanced toughness and wear resistance for high-performance operation. |
| Roller bearing | 1.7147 (50-55 HRC) | 10-25 mm | High hardness ensures reliability under heavy load conditions. |
| Ball bearing | G12144 (58-62 HRC) | 5-20 mm | Enhanced durability for applications with dynamic loads. |
Selecting the right plate
Opt for higher grades
Higher grade materials improve wear resistance and durability.
Consider thickness carefully
Thicker bars can provide additional strength and stability.
Match tight tolerances
Ensuring precise dimensions is crucial for bearings' performance.
Evaluate surface finish
Smooth finishes minimize friction and enhance durability.
Questions engineers ask
What is the advantage of using cold drawn bars?
Cold drawn bars offer superior dimensional accuracy and surface finish. This is essential for producing reliable components that function optimally without the need for further processing.
How does grade selection affect bearing performance?
Choosing the right grade impacts wear resistance and the ability to withstand loads. Higher grades typically provide better performance in demanding applications.
What is the significance of surface finish?
A fine surface finish helps reduce friction and wear between moving parts. This prolongs the life of bearings and ensures efficient operation.
What thickness range should I consider?
The thickness should be selected based on the specific application and load requirements. A balance between strength and weight is crucial for optimal performance.
