**Key Factors to Consider**
When selecting ball or roller bearings for your next project, it's essential to understand three critical factors: contact angle, preload, and system rigidity.
**1. Contact Angle**
This refers to the angle at which the bearing’s balls make contact with the raceways. The ideal contact angle is typically 15°, providing a balanced combination of axial and radial load capacity and rigidity. Some systems may use a 25° contact angle to enhance axial stiffness. Choosing the right angle is crucial for optimal performance and longevity.
**2. Preload**
Preload is the controlled force applied to the bearing to eliminate play and ensure stability under load. It helps prevent uncontrolled movement and ensures smooth operation. The right bearing design allows it to handle this force without compromising its integrity.
**3. System Rigidity**
The rigidity of the entire system plays a vital role in the performance of bearings. Factors like housing stiffness and bearing stiffness determine how well the machine can maintain precision and consistency during operation.

**Maintenance and Care Tips**
Bearings have a predetermined service life, determined by the number of rotations they can withstand before wear affects performance. Several factors can shorten this lifespan:
- **Inefficient seals**: Full-contact seals or poorly calibrated ones can cause excessive wear.
- **High speeds or rapid speed changes**: Excessive speed increases friction and wear, while sudden changes can lead to slippage.
- **Poor environmental conditions**: Dust, moisture, and other contaminants can damage surfaces and reduce performance.
To extend the life of your bearings, regular maintenance is key. Two important practices include cleaning and re-greasing:
- **Grease storage**: Store grease in sealed containers at stable temperatures. Avoid using grease older than three years.
- **Grease application**: Clean and dry the bearings before applying grease evenly between the rolling elements. Use clean tools to avoid contamination.
