FAQ What does the ‘DDUCM’ suffix signify for this NSK bearing?The ‘DDU’ indicates that the bearing is equipped with contact rubber seals on both sides, providing excellent protection against contamination and retaining grease. The ‘CM’ designates a specific internal clearance and noise/vibration level suitable for electric motor applications. Is this bearing suitable for high-speed applications?While DDU seals offer great protection, they create more friction than non-contact seals (ZZ) or open bearings. This bearing is suitable for moderate speeds. For very high-speed applications, a bearing with non-contact shields or an open design might be more appropriate, depending on the operating environment. What is the recommended lubrication for a 6310DDUCM bearing?This bearing comes pre-lubricated from the factory with a high-quality grease designed for a long service life. As it is a sealed unit (‘sealed-for-life’), it does not require re-lubrication under normal operating conditions. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
