6208ZZ Deep Groove Ball Bearings 1218581216
The 6208ZZ bearing is a deep groove ball bearing with a sealed design, widely used in various industrial machinery. Its main parameters are as follows:
Model: 6208ZZ (older models may be marked as 6208-2Z or 6208-ZZ)
Bearing Type: Deep Groove Ball Bearing
Inner Diameter (d): 40 mm
Outer Diameter (D): 80 mm
Width (B): 18 mm
Minimum Chamfer Radius (r): 1.1 mm
Weight: Approx. 0.366 kg
Load Capacity
Rated Dynamic Load (Cr): 29.1 kN (approx. 2970 kgf)
Rated Static Load (Cor): 17.8 kN (approx. 1820 kgf)
Lubrication and Speed
Grease Lubrication Limiting Speed: 8300–8700 r/min (slightly different for different brands)
Oil Lubrication Limiting Speed: 10000 r/min
General Parameters: Some sources list the rated dynamic load of the 6208 series as 29.5 kN. kN, static load is 18.0 kN, grease lubrication speed is 8000 r/min. These values may be based on different standards or approximations. Applications: Suitable for applications requiring radial and partial axial loads, commonly found in: Belt conveyors, bucket elevators, boiler auxiliaries, dust humidifiers, machine tool spindles, automobiles, motors, and construction machinery.
Note: "ZZ" in 6208ZZ indicates that both sides are metal-sealed covers (non-contact type), effectively preventing dust ingress and retaining lubricant, suitable for medium speeds and general industrial environments.
