Bearing Catalog
The F6202ZZ is a flanged single-row deep groove ball bearing featuring metal shields on both sides (designated ZZ). The flange on the outer ring simplifies axial positioning — ideal when you need an exact stop or to prevent axial movement without additional retaining components. Its compact size and reliable performance make it a common choice in small motors, gearboxes, household appliances, instruments, and automation equipment.
Flanged outer ring for easy positioning
Double metal shields (ZZ) — good dust protection and low friction
High radial load capacity for its size
Low noise and smooth operation at high speed

Common uses for the F6202ZZ include:
Small electric motors and fans
Gearboxes and transmission units
Household appliances (washing machines, vacuum cleaners)
Office equipment (printers, scanners)
Robotics, automation actuators
Textile and packaging machinery
1. Verify housing bore and shaft tolerances: recommended shaft tolerance h6 for most applications.
2. Use a press-fit only on the bore (inner ring) — avoid pressing on outer ring to prevent ring distortion.
3. Ensure the flange is used as a locating surface; if the housing contains a ledge or recess, confirm clearance with flange diameter.
4. Do not pry under the lip of metal shields — shields protect seals but are thin and can be damaged.
5. For high-speed applications, check bearing runout and alignment; use appropriate lubricants if replacing grease.
Most F6202ZZ bearings are supplied pre-lubricated and sealed for life under normal operating conditions. For heavy-duty or harsh environments, consider:
Periodic inspection for noise, vibration, or temperature rise.
Replacing bearings rather than re-lubricating if shields are non-removable.
Using stainless steel variants or special coatings in corrosive environments.
Standard material: chrome bearing steel (GCr15). Alternatives and upgrades:
Stainless steel (AISI 440C) for corrosion resistance.
Ceramic balls (hybrid bearings) for reduced weight and higher RPM capability.
Contact rubber seals (RS) instead of metal shields (ZZ) when better sealing is required.
| Model | Shield/Seal | Use Case |
|---|---|---|
| F6202ZZ | Double metal shields (ZZ) + flange | Positioning + light dust protection + high speed |
| 6202-2RS | Double rubber seals (2RS) | Better sealing vs contamination, slightly higher friction |
| 6202 | No seals | For custom lubrication and lower cost |
Common part numbers and suffixes:
F6202ZZ — flanged outer ring, metal shields both sides.
F6202-2RS — flanged, rubber seals both sides (if available).
Confirm manufacturer-specific flange diameter (Df) and dynamic load ratings when ordering in bulk.
Q: What does ZZ mean on a bearing?
ZZ indicates the bearing has metal shields on both sides. These shields protect against dust and reduce contamination while allowing relatively low friction compared to rubber seals.
Q: What is the flange for?
The flange on the outer ring provides an axial locating surface, simplifying installation and preventing axial movement without separate retaining rings.
Q: Can I re-lubricate an F6202ZZ?
Many are pre-lubricated and meant for life; re-lubrication is possible if shields are removable, but in many small bearings they are not designed for easy re-greasing. Consult the manufacturer’s datasheet.
Q: What shaft tolerance should I use?
Typical recommendation is h6 for general applications. For precision/high-speed use, consult fit tables and manufacturer guidance.
Q: Is F6202ZZ interchangeable with 6202ZZ?
Dimensionally the underlying 6202 follows standard dimensions (15×35×11). The leading F indicates the flanged outer ring; interchangeability depends on whether a flange is required by the housing design.
