[10] 6006 bearings 6006 deep groove ball bearings
NSK 6005, 6006, 6005zz, 6006zz, and 2RS series deep groove ball bearings are engineered for high-speed performance and durability. The brass cage ensures reduced friction and extended service life. ensures reduced friction and extended service life.
Model | Bore Diameter (mm) | Outer Diameter (mm) | Width (mm) | Load Capacity (kN) | Shield/Seal Type |
---|---|---|---|---|---|
6005 | 25 | 47 | 12 | 10.5 | Open |
6005zz | 25 | 47 | 12 | 9.8 | Metal Shield |
6006 | 30 | 55 | 13 | 13.5 | Open |
6006zz | 30 | 55 | 13 | 12.2 | Metal Shield |
6005-2RS | 25 | 47 | 12 | 9.0 | Rubber Seal |
Note. 2RS variants offer superior dust/water resistance but slightly lower speed ratings due to increased friction.
A Turkish textile plant replaced generic bearings with NSK 6006-2RS in spinning machinery, reducing downtime by 40% and operating temperatures by 18°C.
NSK 6005zz bearings with brass cages were installed in a German packaging line's washdown area, surviving 12,000+ hours of high-pressure cleaning without corrosion.
Requirement | Recommended Model | Rationale |
---|---|---|
High-Speed Operations | 6005/6006 (Open) | Lower friction for RPM above 8,000 |
Harsh Environments | 6005zz/6006-2RS | Shields/seals block contaminants |
Corrosive Settings | Stainless Steel Variants | Resist chemical/water exposure |
Challenge. Frequent bearing failures in mining excavators.
Solution. Customised NSK 6006 bearings with reinforced brass cages.
Result. Service life extended from 6 to 18 months.
Challenge. Bearing lubrication loss in -30°C conditions.
Solution. Low-temperature grease-packed 6005-2RS units.
Result. Maintenance intervals increased from quarterly to biannually.
