Product Selection Differences for Slewing Ring Bearings

When selecting slewing ring bearings, there are several key differences to consider:

1. Design Type:

   • Single Row: Compact design suitable for light to moderate loads.
   • Double Row: Higher load capacity and stiffness compared to single-row designs.
   • Cross Roller: Offers high rigidity and precision for applications requiring tight tolerances.

2. Load Capacity:

   • Dynamic Load Capacity: The maximum load a bearing can sustain while rotating.
   • Static Load Capacity: The maximum load a bearing can support without incurring permanent deformation.

3. Size and Mounting:

   • Consider the size of the bearing in relation to the space available for installation.
   • Different mounting methods may affect overall system design and performance.

4. Sealing and Lubrication:

   • Sealed bearings are protected from contaminants and require less maintenance.
   • Lubrication method (grease, oil) can impact bearing performance.

5. Operating Conditions:

   • Consider factors such as temperature, speed, shock loads, and environmental conditions when selecting bearings.

6. Precision and Rigidity:

   • High-precision bearings are suitable for applications requiring accurate positioning.
   • Rigidity is critical for maintaining positional accuracy under varying loads.

7. Manufacturer Reputation:

   • Partnering with reputable manufacturers ensures product quality and reliable performance.

8. Cost and Longevity:

   • Balance initial cost with long-term durability and expected lifespan of the bearing.

By evaluating these factors in relation to your specific application requirements, you can choose the most appropriate slewing ring bearing for your needs.
