Frequently Asked Questions
Q: What are the NSK 6201DDU bearing specifications?
A: The NSK 6201DDU is a sealed deep groove ball bearing with 12 mm bore, 32 mm outer diameter, 10 mm width, and a dynamic load rating of 7500 N. It uses a pressed steel cage and is manufactured from through-hardened chromium steel equivalent to SAE 52100.
Q: What equivalent bearings can replace the 6201DDU?
A: The 6201DDU is equivalent to 6201DU and 6201-2RS. These cross-reference numbers indicate compatible interchange bearings for manual pallet jack wheel hubs.
Q: What type of seals does the 6201DDU use and what is their purpose?
A: The 6201DDU features nitrile rubber contact seals on both sides. These seals make contact with the bearing races to exclude water, dirt, and contamination, making the bearing suitable for wet floor and warehouse material handling applications.
Q: How do the 6201DDU seals compare to other bearing seal options?
A: Contact seals (DDU designation) provide active sealing compared to non-contact designs. This delivers better protection against liquid ingress in cold storage and water-exposed environments, though they may increase friction slightly compared to non-contact seals.
Q: What material is used for the cage in the 6201DDU bearing?
A: The 6201DDU uses a pressed steel cage, which is economical and reliable for standard manual pallet jack wheel hub applications.
