The MRC 206MFG is a special execution of the MRC 206M maximum-capacity radial ball bearing.

Its principal dimensions are:

30 × 62 × 16 mm

which are shared with the common modern 6206 dimensional family.

However, internally the 206M is different from a conventional 6206.

The M / Maximum Capacity design incorporates filling slots in the raceways. This allows additional balls to be installed and increases radial load-carrying capability.

The trade-off is that filling-slot bearings generally have more restricted axial-load capability than standard non-filling-slot deep groove bearings.

⚙️ Applications

• Electric motors
• Industrial gearboxes
• Pumps
• Fans and blowers
• Conveyor systems
• Industrial rollers
• Processing machinery
• Agricultural equipment
• Power-transmission systems
• Machinery with relatively high radial loads

🎯 Benefits

✔ Standard 30 × 62 × 16 mm mounting envelope

✔ Maximum-capacity filling-slot construction

✔ Increased ball complement

✔ Higher radial-load capability than a conventional deep groove bearing of similar size

✔ Single-row radial ball bearing

✔ Suitable for industrial machinery with radial-load-dominant duty

✔ Legacy MRC special execution

✔ Cross-reference possible when internal construction and suffix requirements are matched

Suitable cross-reference search candidates include:

• MRC 206MFG
• MRC 206M
• Maximum Capacity 206 Bearing
• 30x62x16 Filling-Slot Ball Bearing
• NSK BL206 family
• NTN BL206 family
• Maximum-Capacity / Max-Type 30x62x16 Ball Bearing

Important: MRC 206MFG Is Not Automatically a Standard 6206

Both bearings may share:

30 × 62 × 16 mm

but their internal construction differs.

MRC 206MFG

• Maximum-capacity design
• Filling slots
• Increased ball complement
• Designed for increased radial capacity
• Axial-load capability more restricted
• Special FG execution

Standard 6206

• Conventional Conrad-type deep groove construction
• No filling slots
• More balanced radial + moderate axial load capability
• Different load and speed characteristics

Therefore:

206MFG ≠ automatically 6206

even though the dimensional envelope is identical.

Why the Filling Slot Matters

A conventional deep groove bearing must assemble the ball complement within the continuous raceway geometry.

A filling-slot bearing adds loading notches that allow more balls to be installed.

This provides:

✔ More rolling elements
✔ Greater radial load capacity
✔ Better suitability for radial-load-dominant machinery

But it also introduces a limitation:

The filling slots interrupt part of the raceway shoulder, so substantial axial loads can bring the balls into the filling-slot region.

For this reason, a Max-Type bearing should not normally be selected for pure thrust or high axial-load service without checking the original design requirements.

Important: Preserve the “FG” Suffix

The complete part number is:

206MFG

not merely:

206M

and not:

6206

Until original MRC documentation confirms exactly what the F and G execution features represent, a replacement should preserve those details during technical review.

Before substitution, verify:

• Closure / shield arrangement
• Lubrication
• Internal clearance
• Cage
• Precision requirement
• Special grease specification, if any
• Radial load
• Axial load
• Speed
• Temperature
• Shaft fit
• Housing fit

(Always verify the original MRC 206MFG bearing and its FG execution before selecting MRC 206M, NTN BL206, NSK BL206, standard 6206, or another replacement.)
