Product Q&A

Q:What precision grades are available for NCF30 series bearings?

We offer full coverage of premium precision grades including P2, UP, P4, SP, P5, and P6 to meet high-precision industrial requirements.

Q:Can the bearings be customized with specific lubrication features?

Yes, optional K (tapered bore) and W33 (circumferential lubrication groove with oil holes) configurations are available to improve assembly adaptability.

Q:What are the main applications for these bearings?

They are widely used in CNC machine tool spindles, industrial robot joints, heavy-duty metallurgical rolling mills, mining machinery, and wind power equipment.

Q:How should the bearings be installed to avoid damage?

Do not apply force to rolling elements or strike the rings. Use a heater or fixture, and tighten screws in three stages (40%, 70%, 100%) using a cross pattern.

Q:Are the bearings pre-filled with grease upon shipment?

Yes, unless otherwise specified. If oil lubrication is required, they are shipped with only minimal anti-rust oil.
