FAQs About 3/4 Pillow Block Bearings
- What is the difference between a pillow block bearing and a ball bearing?
- Pillow block bearings are mounted within a housing that supports the bearing and shaft, while ball bearings are typically mounted directly onto the shaft.
- How do I choose the right 3/4 pillow block bearing?
- Consider the bore diameter, width, height, load capacity, and operating conditions. Refer to industry standards or consult with a bearing manufacturer.
- How often should I lubricate a 3/4 pillow block bearing?
- Lubrication frequency depends on the application and operating conditions. Consult the manufacturer's recommendations for specific intervals.
