The FAFNIR 200DD is a compact single-row deep groove ball bearing designed primarily for radial loading while also supporting moderate axial load in both directions.

Its dimensional envelope is:

10 × 30 × 9 mm

which corresponds to the modern standard:

6200

The DD suffix is particularly important. In historical FAFNIR nomenclature:

D = Single Shield
DD = Double Shield

Therefore, the closest modern starting point for cross-reference is normally the:

6200-2Z / 6200ZZ

double-metal-shielded family rather than a rubber-sealed 6200-2RS. BDS Bearing

⚙️ Applications

• Small electric motors
• Pumps
• Fans and blowers
• Gearboxes
• Power tools
• Light conveyor systems
• Industrial instruments
• Small rollers
• Agricultural equipment
• General rotating machinery

🎯 Benefits

✔ Standard 10 × 30 × 9 mm dimensions

✔ Single-row deep groove construction

✔ Double metal shields

✔ Good grease retention

✔ Lower running friction than typical contact rubber seals

✔ Good radial-load capability

✔ Supports moderate axial load in both directions

✔ Suitable for relatively high-speed applications when operating conditions permit

✔ Modern 6200-2Z / 6200ZZ replacements widely available

FAFNIR 200DD → Modern 6200 Family

The dimensional relationship is:

FAFNIR 200DD = 10 × 30 × 9 mm

which matches:

6200

Because the FAFNIR DD suffix specifically means Double Shield, the most technically appropriate modern family to investigate first is:

6200-2Z / 6200ZZ BDS Bearing

Important: DD vs PP

Historical FAFNIR nomenclature should not be mixed indiscriminately.

For FAFNIR:

DD → Double Shield

Other FAFNIR designations, such as PP, are used for different closure constructions in some product families.

Therefore:

FAFNIR 200DD ≠ automatically FAFNIR 200PP

even though both may use the same basic 10 × 30 × 9 mm envelope.

6200-2Z vs 6200-2RS

Both commonly use:

10 × 30 × 9 mm

but closure design differs.

6200-2Z / ZZ

• Metal shields on both sides
• Lower friction
• Good grease retention
• Generally better suited to higher speed
• Helps exclude larger dust and debris

6200-2RS / 2RSH

• Rubber seals
• Better exclusion of fine dust and moisture
• Higher friction
• Usually lower allowable speed than comparable shielded versions

For the original FAFNIR 200DD, the 6200-2Z / ZZ family is therefore normally a closer constructional cross-reference than 6200-2RS.

Important Cross-Reference Consideration

Before replacing FAFNIR 200DD, verify:

• Bore = 10 mm
• OD = 30 mm
• Width = 9 mm
• Double metal shields
• Internal clearance
• Cage
• Lubricant
• Precision class
• Operating speed
• Load requirement
• Shaft fit
• Housing fit

(Always verify the original bearing marking and machine requirements before selecting SKF 6200-2Z, FAG 6200-2Z, NTN 6200ZZ, NSK 6200ZZ, MRC 200SZZ, or another replacement.)
