Leading Precision Crossed Roller Bearings Manufacturer in China

BYBearings is short for Luoyang BoYing Bearings Co.Ltd., or Boying Bearings Corporation, a professional high-precision bearing manufacturer for over 10 years.

While a standard bearing might have a few microns of "runout" (wobble), high-precision bearings are engineered to have near-zero deviation. They use higher-grade steel, more perfectly spherical balls, and specialized raceway grinding.

The Result: Better rotational accuracy, less heat generation, and the ability to spin at much higher RPMs without vibrating.

BYBearings is a professional high-precision bearing manufacturer with a factory of over 100 acres.

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).
