The MRC 209MZZ1 is a special MRC (SKF) single-row deep groove ball bearing with dimensions of approximately:

35 × 82 × 27 mm

or in inch dimensions:

1.378 × 3.226 × 1.062 in

The bearing is supplied with protection on both sides and is intended for applications where the original equipment requires this specific combination of bore, outside diameter, width, and enclosure.

The dimensions are particularly important because they are not the standard dimensions normally associated with a conventional 209 / 6209 bearing.

A standard 6209 commonly uses:

45 × 85 × 19 mm

whereas the supplied MRC 209MZZ1 specification is:

35 × 82 × 27 mm

Therefore, these bearings are not dimensionally interchangeable.

⚙️ Applications

• Legacy industrial machinery
• OEM equipment using special MRC bearing dimensions
• Electric motors
• Gearboxes
• Pumps
• Fans and blowers
• Industrial rollers
• Processing machinery
• Power-transmission equipment
• Special replacement-bearing applications

🎯 Benefits

✔ Special OEM-style dimensional configuration

✔ 35 mm nominal bore

✔ Approximately 82 mm outside diameter

✔ Approximately 27 mm overall width

✔ Single-row deep groove construction

✔ Double-side sealed protection

✔ Helps retain lubricant

✔ Helps protect the rolling elements from contamination

✔ Suitable for replacement of legacy MRC applications when dimensions match

🔁 Equivalent

Suitable replacement or cross-reference search terms include:

• MRC 209MZZ1
• MRC SKF 209MZZ1
• 1.378x3.226x1.062 Bearing
• 35x82x27 Ball Bearing
• 35 mm Bore Special Ball Bearing
• 82 mm OD Double Sealed Bearing
• Special Dimension Deep Groove Ball Bearing

Important: 209MZZ1 Is Not a Standard 6209

This is the most important point when sourcing a replacement.

MRC 209MZZ1

• Bore ≈ 35 mm
• OD ≈ 82 mm
• Width ≈ 27 mm
• Special MRC configuration

Standard 6209

• Bore = 45 mm
• OD = 85 mm
• Width = 19 mm

Therefore:

MRC 209MZZ1 ≠ Standard 6209

The difference is substantial:

• Bore differs by approximately 10 mm
• OD differs by approximately 3 mm
• Width differs by approximately 8 mm

A standard 6209 therefore cannot physically replace this special bearing in the same shaft and housing.

Inch-to-Metric Conversion

The supplied dimensions convert as follows:

1.378 in × 25.4 = 35.0012 mm

3.226 in × 25.4 = 81.9404 mm

1.062 in × 25.4 = 26.9748 mm

For practical catalog use, these can be described as approximately:

35 × 82 × 27 mm

However, for replacement selection, the original inch dimensions should also be retained because the bearing may have been designed around inch-based manufacturing dimensions.

Cross-Reference Strategy

For this bearing, searching only for:

209 bearing

or:

6209

may lead to the wrong product.

A better search strategy is:

MRC 209MZZ1 + 1.378 × 3.226 × 1.062 in

or:

MRC 209MZZ1 + 35 × 82 × 27 mm

When evaluating another brand, verify:

• Exact bore
• Exact OD
• Exact width
• Seal construction
• Internal clearance
• Cage
• Raceway geometry
• Load ratings
• Speed capability
• Lubrication
• Shaft fit
• Housing fit

(Always verify the complete 209MZZ1 dimensions and execution before selecting another MRC, SKF, NTN, NSK, FAG, or other-brand bearing as a replacement.)
