FAQs
1. Who is BYBearings?
2. What makes a bearing "High Precision"?
The Result: Better rotational accuracy, less heat generation, and the ability to spin at much higher RPMs without vibrating.
3. Are you a supplier or manufacturer?
4. What is the diff between RB, RE & RU series?
These series are standard designs widely used across the industry, compatible with standard dimensions.
- RB Series: Separable outer ring with a solid inner ring. Best when you need high rotation accuracy on the inner ring.
- RE Series: Separable inner ring with a solid outer ring. Best when the outer ring is the part that will be rotating.
- RU Series: Both rings are solid with pre-drilled mounting holes. Easiest to install (no specialized housing flanges needed).
