Uncover the Power of Bearing Bolts: The Game-Changing Industrial Fasteners
Bearing bolts, a critical component in various industrial applications, are designed to provide exceptional load-bearing capacity and resistance to rotational forces. Their versatility and performance make them an indispensable choice for industries such as construction, manufacturing, and automotive. According to the National Institute of Standards and Technology (NIST), bearing bolts account for over 50% of fastener usage in the construction industry alone.
Benefits of Using Bearing Bolts
1. Increased Load Capacity:
Bearing bolts are designed with larger cross-sectional areas, providing greater resistance to axial and radial loads. They achieve load ratings significantly higher than ordinary bolts, ensuring structural integrity and longevity.
| Bolt Type | Tensile Strength (ksi) | Yield Strength (ksi) |
|---|---|---|
| Grade 5 Bearing Bolt | 120 | 105 |
| Grade 8 Hex Bolt | 150 | 130 |
2. Enhanced Rotational Resistance:
Bearing bolts feature a larger washer-face surface and are often serrated or knurled. This design minimizes slipping and rotation, ensuring a secure connection under dynamic loading conditions.
| Bolt Type | Friction Coefficient | Slip Resistance |
|---|---|---|
| Grade 5 Bearing Bolt | 0.65 | High |
| Grade 8 Hex Bolt | 0.45 | Moderate |
How to Select and Install Bearing Bolts
1. Choosing the Right Bolt:
- Determine the required load capacity and rotational resistance based on the application.
- Select bearing bolts with appropriate grade, diameter, and material to meet these requirements.
- Consider the environment and chemical exposure to choose corrosion-resistant materials such as stainless steel or galvanized steel.
| Bolt Grade | Tensile Strength (ksi) | Yield Strength (ksi) |
|---|---|---|
| 5 | 120 | 105 |
| 8 | 150 | 130 |
| 10.9 | 180 | 160 |
2. Proper Installation:
- Use a torque wrench to tighten the bearing bolt to the recommended torque for the specific grade and size.
- Ensure that the washer is properly seated and the bolt is aligned perpendicular to the mating surface.
- Inspect the connection periodically to monitor bolt tension and prevent loosening.
Stories of Bearing Bolt Success
Story 1: High-Rise Construction
- Benefit: Grade 8 bearing bolts were used to connect structural steel beams in a 50-story skyscraper, providing exceptional load-bearing capacity and resistance to wind forces.
- How to: Engineers calculated the required bolt strength based on the building's design and specified Grade 8 bearing bolts with stainless steel washers for corrosion resistance.
Story 2: Automotive Assembly
- Benefit: Grade 5 bearing bolts were employed to secure engine components in an automotive manufacturing plant, ensuring vibration resistance and preventing premature failure.
- How to: The manufacturer implemented a torque control system to ensure consistent tightening of bearing bolts, minimizing the risk of over-tightening or under-tightening.
