Effective Strategies for Optimal Performance

• Use preloading to improve bearing stiffness and reduce vibration.
• Ensure proper lubrication to minimize friction and wear.
• Monitor bearing condition through vibration and temperature analysis.

Common Mistakes to Avoid

• Exceeding the bearing's load capacity can lead to premature failure.
• Incorrect mounting or handling can damage the bearing raceways.
• Inadequate lubrication can result in accelerated wear and tear.

Advanced Features

• Ceramic balls: Provide exceptional wear resistance and high-temperature performance.
• Solid lubricants: Enhance bearing performance in harsh environments.
• Seals: Protect the bearing from contamination.

Challenges and Limitations

• Higher cost: Angular contact bearings are typically more expensive than radial or thrust bearings.
• Axial load limitations: The axial load capacity is limited by the contact angle and the bearing size.
• Precision: Manufacturing tolerances are critical to ensure optimal bearing performance.

Potential Drawbacks and Mitigating Risks

• Noise: Angled raceways can generate noise, which can be mitigated by using cages or synthetic lubricants.
• Contamination: Proper sealing is essential to prevent contamination that can damage the bearing.

Pros and Cons
