FAQ

What is the correct tightening torque for the set screws on the UELP309-11 1D1 bearing?

The recommended tightening torque for the set screws on this bearing insert is typically around 29-33 N-m (Newton-meters). Always refer to the official NTN installation manual for the most accurate specifications to prevent shaft damage or bearing slippage.

Can this bearing unit be relubricated, and what type of grease should be used?

Yes, the P309 housing is equipped with a grease fitting for relubrication. It is factory-lubricated, but for ongoing maintenance, use a high-quality lithium-based grease with a consistency of NLGI 2. Ensure compatibility with the existing grease to avoid degradation.

What does the self-aligning feature of this pillow block accommodate?

The bearing insert has a spherical outer surface that mates with a corresponding spherical surface in the housing. This allows the bearing to swivel, accommodating initial static misalignment of the shaft up to approximately +/- 2 degrees, which simplifies installation and reduces stress on the bearing.
