1205K Self-aligning Ball Bearings
The 1205K bearing is a SKF.NTN.FAG.NSK with an inner diameter of 25 mm , an outer diameter of 52 mm, a width of 15 mm. It typically uses P0 grade precision tolerances and open,ZZ,2Z,2RS type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Ceramic ball bearing especially 1205k have the following performance as low density, high strength, low friction coefficient, electrical and magnetism resistance, wear resistance, well rigidity, lubrication and maintenance free when working, it's the best choice for rollers (inner ring and outer ring are made by metal) of the hybrid construction which are used in high-speed, high accuracy and long life environments.
Compared with steel ball, 1205k ball has following advantages:
- 23%lighter than steel ball, which means less centrifugal force and less friction on the groove during high speed and acceleration.
- Smaller fiction coefficient, more freely rolling.
- Can be used at higher temperature up to 750°C
- Never rust, and can roll with out lubrication.
- More corrosion resistant than steel
- No metal contamination.
- Non-magnetic
- Electric isolation
