Product Q&A

Q:What precision grades are available for NCF29 bearings?

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

Q:What is the difference between K and W33 configurations?

K indicates a tapered bore for flexible shaft matching, while W33 features a circumferential lubrication groove with oil holes on the outer ring to improve lubrication efficiency.

Q:Are these bearings suitable for heavy machinery applications?

Yes, they are widely used in heavy-duty metallurgical rolling mills, mining machinery, large motor shafts, and marine propulsion systems due to their super-strong radial load capacity.

Q:How should the bearings be lubricated?

Bearings are pre-filled with grease upon shipment. For oil lubrication, specify in the order form. Do not mix different grease brands, and replenish every 6-12 months based on conditions.

Q:What is the Minimum Order Quantity (MOQ)?

The Minimum Order Quantity is 1 set.
