Series 6200ZZ C3
Series 6200ZZ C3 is a group of 16 IMPA-coded items (codes 770651–770666) under Single Row Deep Groove Radial Ball Bearings in the Bearings section (IMPA 77). All of them are priced per piece.
Buying guide
The 6200 series is the light-series single-row deep groove ball bearing. This group holds the ZZ C3 version: metal shields on both sides and increased radial internal clearance, in bore sizes from 6200 upward.[1]
It is the common bearing of electric motors, pumps and fans on board. The engineer raises it against the machinery spare-parts list or when a bearing runs noisy or hot.
How to specify it
Give the full designation. In 6205, “62” is the light series and “05” the bore code: multiply by 5 for the bore in mm (25 mm). ZZ (2Z) means a shield each side; RS/2RS, DDU or VV mean rubber seals instead, and these seal codes vary by maker. Do not drop the suffixes on the requisition.[1]
Keep the clearance class. C3 is increased clearance over normal (CN, usually shown with no suffix); electric-motor bearings are almost always C3 because the inner ring expands as the motor warms and a normal-clearance bearing can seize.[1]
Rules and certificates
Boundary dimensions of radial bearings follow ISO 15:2017, which sets preferred boundary dimensions for diameter series 7, 8, 9, 0, 1, 2, 3 and 4; that is why a 6205 from different makers is dimensionally interchangeable.[2]
Questions buyers ask
- Is 6205ZZ the same as 6205-2Z?
- Yes: both mean shields on both sides. Makers use slightly different suffix conventions for the same bearing.
- Can I fit a normal-clearance bearing where C3 was fitted?
- Avoid it, especially in electric motors: C3 allows for the inner ring expanding as the machine warms; with normal clearance the bearing can seize.
